How to use Sparkolloid finings when making wine

Sparkolloid. 

It sounds like some kind of strange alien planet.

The reality is that it is a very handy fining agent for use when making wine or mead. 

Sparkolloid is a popular inorganic fining clarifier agent widely used in the winemaking industry for its remarkable ability to clarify and stabilize wines. It is known for its natural composition and its effectiveness in enhancing wine clarity.

Sparkolloid is composed of a blend of diatomaceous earth, a type of fossilized algae, and purified isinglass, a substance derived from fish bladder. This combination of natural materials creates a fining agent with excellent clarifying properties. It comes in powder form:

One of the key properties of Sparkolloid is its high adsorption capacity. It has a strong affinity for haze-causing compounds, proteins, and unwanted particles present in wine. When added to the wine, Sparkolloid attracts and binds with these substances, forming larger particles that precipitate out of the liquid, resulting in a clearer wine.

Compared to other fining agents, Sparkolloid offers several advantages. Firstly, it is a natural fining agent, appealing to winemakers who prefer to minimize the use of synthetic substances in their winemaking process. Its composition of diatomaceous earth and purified isinglass aligns with the demand for more natural and sustainable winemaking practices.

Secondly, Sparkolloid demonstrates a high level of effectiveness in achieving wine clarity. Its ability to remove haze-causing compounds, such as proteins and tannins, is particularly notable. The resulting wine exhibits improved brilliance, color stability, and reduced sedimentation.

Furthermore, Sparkolloid is relatively easy to use. It can be added directly to the wine and does not require extensive preparation or complicated procedures. Winemakers appreciate the convenience and efficiency that Sparkolloid offers in the fining process.

Overall, Sparkolloid stands out as a reliable and efficient fining agent, renowned for its natural composition, outstanding clarifying properties, and ease of use. In the next sections, we will delve into the step-by-step process of using Sparkolloid in winemaking, enabling you to harness its potential and enhance the clarity of your wines.

How Sparkolloid works

To understand the fining capabilities of Sparkolloid, it's essential to explore the science behind its mechanism of action. Sparkolloid interacts with various wine components, particularly proteins and tannins, to achieve its clarifying and stabilizing effects.

When Sparkolloid is added to the wine, its diatomaceous earth component acts as a matrix with a vast surface area. This surface area provides binding sites for the wine's proteins and tannins, which are responsible for haze formation and color instability.

Proteins, often derived from grape juice or yeast, can contribute to haze in wine. These proteins can form complexes and cause turbidity, negatively impacting the wine's visual appeal. Sparkolloid's diatomaceous earth absorbs and binds to these proteins, removing them from the wine matrix. This process is known as adsorption.

Similarly, tannins, which are natural compounds found in grape skins, seeds, and stems, can also contribute to haze formation and color instability. Sparkolloid's isinglass component interacts with these tannins, forming insoluble complexes. These complexes precipitate out of the wine, leading to improved color stability and clarity.

The combined action of Sparkolloid's diatomaceous earth and isinglass components effectively reduces the concentration of haze-causing compounds, proteins, and tannins, resulting in a clearer and more stable wine.

Furthermore, Sparkolloid also aids in the removal of suspended particles, such as sediment or colloidal materials, from the wine (parsnip?). These particles can contribute to a cloudy appearance or unpleasant texture in the final product. Sparkolloid's binding action helps agglomerate these particles into larger, more settleable forms, allowing for easier removal during racking or filtration.

By targeting proteins, tannins, and suspended particles, Sparkolloid significantly enhances wine clarity, stability, and overall sensory experience.

How to use Sparkolloid finings when making wine

When using Sparkolloid as a fining agent, it's important to determine the optimal timing and dosage for its addition. Additionally, certain factors like pH and temperature should be considered to ensure its effectiveness. 

Let's explore a step-by-step guide on incorporating Sparkolloid into the winemaking process.

1. Timing: The optimal timing for Sparkolloid addition varies depending on the specific winemaking scenario. In general, it is recommended to add Sparkolloid after fermentation is complete, and any desired aging or clarification steps have taken place. This timing ensures that the majority of yeast sediment has settled, allowing Sparkolloid to target proteins, tannins, and suspended particles more effectively.

2. Dosage: The recommended dosage of Sparkolloid can vary depending on factors such as wine style, grape variety, and the desired level of clarification. It is advisable to follow the manufacturer's instructions or consult with an experienced winemaker to determine the appropriate dosage. Typically, dosages range from 0.2 to 2 grams per gallon of wine. It's important not to exceed the recommended dosage, as excessive amounts may lead to over-fining and undesirable sensory effects.

3. Preparation: Before adding Sparkolloid to the wine, it's essential to prepare a slurry. To do this, mix the required amount of Sparkolloid with a small amount of warm water, stirring gently until it forms a smooth, lump-free paste. This step helps disperse the fining agent evenly in the wine and ensures proper interaction with the target compounds.

4. Addition: Once the Sparkolloid slurry is prepared, gently stir or mix it into the wine. It's important to distribute the slurry evenly throughout the wine to maximize contact between Sparkolloid and the haze-causing compounds. Avoid excessive agitation, as it can introduce oxygen into the wine and potentially affect its sensory qualities.

5. Settling and Aging: After adding Sparkolloid, allow the wine to settle undisturbed for a recommended period, typically around 2-3 weeks. During this time, the fining agent will work to clarify the wine by attracting and binding with the targeted compounds. Regular monitoring of the wine's clarity and sedimentation is recommended.

6. Racking or Filtration: Once the settling period is complete, carefully rack or filter the wine to separate it from the sediment and any remaining particles. Racking involves transferring the wine to a clean vessel, leaving the sediment behind. Filtration can further enhance the wine's clarity by removing smaller particles. It is important to follow proper sanitation practices during these steps to maintain the wine's quality.

Factors to Consider:

•  pH: Sparkolloid is most effective within a specific pH range. Generally, a pH range of 3.0 to 3.5 is considered optimal. If the wine's pH is outside this range, adjustments may be necessary to achieve better results. Monitoring and adjusting the pH prior to fining can improve Sparkolloid's performance.
• Temperature: Sparkolloid works best at cooler temperatures, typically between 50°F (10°C) and 70°F (21°C). Lower temperatures facilitate the settling and agglomeration of particles, aiding in the clarification process. It's recommended to store the wine at a controlled temperature during the settling period for optimal results.

Sparkolloid's impact on Wine Clarity

The use of Sparkolloid as a fining agent can have a significant impact on wine clarity and various sensory attributes. Let's evaluate its visual impact on wine clarity and brilliance, assess its effect on wine aroma (cherry?) and flavor profile, and explore the connection between wine clarity and consumer perception of quality.

Sparkolloid plays a vital role in enhancing wine clarity and brilliance. By effectively removing haze-causing compounds, proteins, and tannins, it contributes to a visually appealing wine with a crystal-clear appearance. The removal of suspended particles and sediment further adds to the wine's visual attractiveness. A clear and brilliant wine is visually enticing and often perceived as a mark of quality craftsmanship, inviting consumers to indulge in its sensory experience.

While Sparkolloid primarily focuses on improving wine clarity, it can also have subtle effects on the wine's aroma and flavor profile. By removing proteins and tannins that contribute to haze and potential off-flavors, Sparkolloid can enhance the wine's aroma and flavor clarity. It allows the true character and nuances of the wine to shine through, revealing more pronounced and distinct aromas and flavors. Additionally, the removal of sediment and suspended particles can contribute to a smoother and more refined texture, further enhancing the overall sensory experience.

Wine clarity plays a crucial role in shaping consumer perception of wine quality. A clear and visually appealing wine is often associated with meticulous winemaking practices, attention to detail, and high-quality grapes. When consumers observe a wine with excellent clarity, it creates a positive first impression, suggesting a well-crafted product. The visual aspect of wine influences expectations and anticipation, setting the stage for the sensory experience that follows. 

Therefore, achieving optimal wine clarity through the use of fining agents like Sparkolloid can positively influence consumer perception and contribute to a favorable assessment of wine quality.

Comparisons with Other Fining Agents:

When exploring fining agents for wine clarification, it's valuable to contrast Sparkolloid with other commonly used options. Let's highlight the advantages and disadvantages of Sparkolloid in comparison and provide case studies or examples showcasing its efficacy in real winemaking scenarios.

1. Bentonite: Bentonite is an inorganic fining agent widely used in winemaking. It consists of clay minerals with high adsorption properties. While both Sparkolloid and bentonite are effective in clarifying wines, there are notable differences. Sparkolloid tends to have higher adsorption capacity and can target a broader range of haze-causing compounds, including proteins and tannins. Bentonite is particularly effective in reducing unstable proteins but may have limitations in removing certain tannins. Additionally, Sparkolloid is easier to use as it forms a slurry for direct addition to wine, whereas bentonite requires prehydration and careful mixing. They do however complement each other and many wine makers will use both agents.

2. Gelatin: Gelatin, an organic fining agent derived from animal collagen, is commonly used for wine clarification. Gelatin is effective in reducing protein instability and haze formation. However, it may have limitations in removing certain tannins and may require longer settling times. Sparkolloid, with its combined diatomaceous earth and isinglass composition, offers a broader spectrum of fining capabilities, targeting both proteins and tannins more efficiently.

Advantages of Sparkolloid:

• High adsorption capacity for proteins and tannins, resulting in improved clarity.
• Natural composition appeals to winemakers preferring a more organic approach.
• Ease of use with its simple slurry preparation and direct addition to the wine.
• Demonstrated effectiveness in enhancing wine clarity and stability.

Disadvantages of Sparkolloid:

• Sparkolloid contains fish-derived isinglass, which may not be suitable for vegan winemaking practices.
• Some winemakers may find the use of inorganic fining agents less aligned with their overall winemaking philosophy.

Considerations and limitations of using Sparkolloid as a fining agent

While Sparkolloid is an effective fining agent for wine clarification, there are certain considerations and limitations that winemakers should be aware of. Let's discuss potential side effects or challenges associated with Sparkolloid usage, precautions for winemakers, and alternative fining agents for specific winemaking situations or preferences.

Potential Side Effects or Challenges:

• Over-fining: Excessive use of Sparkolloid can lead to over-fining, resulting in a loss of desirable aroma and flavor compounds. It's important to follow recommended dosage guidelines and monitor the wine closely during the settling period to avoid this issue.
• Fish Allergies: Sparkolloid contains isinglass, which is derived from fish. Winemakers should be cautious if they or their consumers have fish allergies or dietary restrictions. Alternative fining agents that are suitable for vegan winemaking practices should be considered in such cases.

Precautions for Winemakers:

• Handling: When preparing the Sparkolloid slurry, it's advisable to wear appropriate protective gear, such as gloves and goggles, as a safety precaution. Avoid inhaling the powder and minimize skin contact.
• Storage: Proper storage of Sparkolloid is crucial to maintain its effectiveness. Store it in a cool, dry place, away from moisture and direct sunlight. Follow the manufacturer's recommendations regarding storage conditions and shelf life.

It's important for winemakers to carefully evaluate their specific winemaking goals, wine characteristics, and consumer preferences when selecting a fining agent. Consulting with experienced winemakers or enologists can provide valuable insights and guidance in choosing the most suitable fining agent for a particular situation.

Sparkolloid is a reliable and effective tool for winemakers seeking to elevate their wines' visual appeal and overall sensory experience. By employing Sparkolloid as a fining agent, winemakers can unlock the full potential of their wines and deliver exceptional quality to wine enthusiasts around the world.

Lalvin D47 Wine Yeast: A Must-Have for Wine Brewers

The Vintner's Choice

Precision in the Cellar: Mastering Lalvin D47

The strain that defines elegance. A deep dive into the fermentation kinetics and sensory profile of the world's premier white wine yeast.

Welcome to the art of winemaking. Whether you’re fermenting cherry, parsnip, or a classic Chardonnay, you already know that ingredient quality shapes everything that follows. Yeast is no exception.

Among the most trusted strains used by home and professional vintners alike, the Lalvin D47 Wine Yeast stands out for its precision and performance. Originally isolated from grapes grown in the Côtes-du-Rhône region of France, this is the strain that helps transform raw juice into something layered, aromatic, and genuinely elegant.

The Gold Standard for Whites & Meads

Clean and Confident Fermentation

Lalvin D47 (Saccharomyces cerevisiae) is renowned for smooth, complete fermentation with minimal fuss. It possesses a moderate lag phase and a regular fermentation rate, which allows it to handle sugar conversion efficiently without "running hot" and stripping away volatile aromas. It consistently produces stable, dry wines without leftover sweetness, provided the nutrient conditions are met.

Its reputation shines in medium- to full-bodied whites (like Chardonnay) and lighter reds such as Pinot Noir, where structure and nuance matter most. Expect wines with crisp balance, controlled acidity, and defined flavor lines that feel intentional rather than accidental.

Aromas that Stay Alive

This yeast is a champion for expressive fruit character. During fermentation, Lalvin D47 exhibits high beta-glucosidase activity. This enzymatic action cleaves the bonds between sugars and aromatic compounds (terpenes), effectively "unlocking" flavors that would otherwise remain dormant and tasteless.

It encourages the release of complex esters that bring out fresh floral and tropical fruit notes, preserving the wine’s natural aroma profile. It is ideal when working with delicate varietals that risk losing their identity during a vigorous fermentation. With this strain, you’ll notice that even subtle notes of pear, apple, citrus, or honey retain their vibrancy through bottling and aging.

The "Danger Zone": Temperature Sensitivity

Master Vintner Warning: While D47 is adaptable, it has one critical weakness. It is highly sensitive to temperatures above 20°C (68°F).

If fermented too warm, D47 is notorious for producing measurable amounts of acetaldehyde (green apple) and fusel alcohols, which taste like harsh solvents or "rocket fuel." To unlock the "silky" texture D47 is famous for, you must maintain a cool, steady environment between 15–20°C (59–68°F). If you cannot control your fermentation temperature during a hot summer, consider a different strain like EC-1118. However, if you have a temperature-controlled chamber, D47 will reward you with unrivaled complexity.

Silky Texture & Sur Lie Aging

Good wine should feel as good as it tastes. Lalvin D47 is a high producer of polysaccharides (complex sugars) during fermentation. These compounds coat the palate, giving the wine a perceived "weight" or creaminess without adding actual sweetness.

This trait makes D47 the premier choice for Sur Lie aging (aging on the lees). When you allow the wine to rest on the yeast sediment for several months (with periodic stirring), the yeast cells break down (autolysis), releasing mannoproteins that further enhance this creamy mouthfeel and stabilize the wine's color. Combined with its ability to promote a gentle malolactic fermentation, D47 creates wines that are round, soft, and harmonious.

Brewer’s Insight: Best Practices

Hydrate Properly

Always rehydrate D47 in chlorine-free water around 35-40°C (95-104°F) for 20 minutes before pitching. This "wakes up" the cell walls, protecting the yeast from osmotic shock when it hits the sugary must.

Feed the Yeast

D47 has a medium nutrient requirement. For low-nitrogen musts (like mead or apple wine), supplement with Fermaid-O or DAP. A stressed yeast will produce sulfur (rotten egg) smells.

Rack Promptly

Unless you are intentionally doing Sur Lie aging with stirring, rack the wine off the gross lees (heavy sediment) within 30 days of fermentation finishing to maintain clarity.

Patience is Key

Wines fermented with D47 benefit immensely from time. A 6-month aging period allows the creamy texture and refined aromatics to fully emerge and integrate.

Final Thoughts

Lalvin D47 Wine Yeast isn’t just another packet on the shelf. It’s a precision tool for crafting wines with character, balance, and longevity. Whether you’re perfecting your first batch or refining your hundredth, this yeast delivers dependability and depth.

Use it for your next home winemaking adventure and experience how a small sachet can elevate the craft into something exceptional.

Beer Ingredient Storage Guide: Hops, Grains, and Yeast

Brewing Architecture: Technical Vol. V

Beer Ingredient Storage Guide Pantry

The Master's Credo:

Keep ingredients punchy. Keep oxygen out. Keep flavor in. This is how you protect the work you put into every brew day.

Seasoned homebrewers learn fast. Freshness wins. Temperature, oxygen, light, and moisture decide whether your lager crackles or your IPA fades. This guide shows smart storage moves for hops, grain, and yeast. We will use airtight containers and vacuum sealers, plus battle-tested habits from the brewhouse.

Pair these with your favorite brewing tips and your ingredients will hold their edge longer. As a Master Brewer, I view ingredients not as static supplies, but as delicate biological and chemical systems. The aromatic compounds in hops (terpenes like Myrcene and Caryophyllene) are highly volatile. Without technical intervention, your "citrus" notes undergo rapid oxidation, transforming into stale, cheesy isovaleric acid.

1

Storage Fundamentals

The Master's Core Principles

The Three Pillars of Preservation

To maintain ingredient integrity, we must combat three primary vectors of decay: thermal energy, ultraviolet radiation, and humidity. Each of these triggers specific molecular breakdowns in your raw materials.

Thermal Stability (2–10°C): Heat acts as a kinetic catalyst for lipid oxidation in malt. Even a $5^\circ C$ fluctuation can stimulate the production of stale aldehydes ($C_n H_{2n} O$). Keep ingredients cool to stall these reactions.

UV Shielding: Light triggers the cleavage of isohumulones in hops. This photochemical reaction is nearly instantaneous. Use opaque bins to prevent the skunking phenomenon.

The Moisture Barrier: Malt is "hygroscopic"—it aggressively absorbs water vapor from the atmosphere. Slack grain loses its friability, leading to a poor crush and significantly reduced mash efficiency. Target humidity levels below 45%.

2

Airtight Containers That Work

Engineering the Perfect Seal

Choosing the Right Barrier

Not all "sealed" bins are created equal. Many low-cost plastics are gas-permeable, allowing oxygen molecules to slowly diffuse through the walls. As a professional, I recommend the following materials based on their specific barrier properties.

Food-Grade Plastics

Gasket-lid HDPE bins are durable and critter-proof. They are perfect for whole base malts used within 6 months. For longer storage, ensure the gasket is silicone, which provides a superior airtight weld compared to standard foam.

Glass & Metal

Mason jars are non-porous and 100% oxygen-impermeable. They are the ideal vessel for hops and dry yeast. Stainless steel canisters are the premium choice for specialty grains, as they block both light and gas definitively.

3

Vacuum Sealing For The Win

Zero-Oxygen Engineering

Vacuum sealers strip headspace oxygen and lock in the punchy aroma profile of hops. By reducing the partial pressure of oxygen ($pO_2$), you essentially put the ingredients into a chemical "stasis." This is critical for preventing the oxidation of alpha acids into humulinic acids, which are unpleasantly bitter and non-aromatic.

Master's Tip: The "Wipe and Weld" Method

Fine dust from milled grain or hop pellets often coats the inner rim of the bag. This dust creates microscopic channels for oxygen to seep back in over time. Always wipe the seal zone with a dry, lint-free cloth before triggering the vacuum and heat-seal cycle.

Quick Targets And Tactics

Biological & Chemical Specs

Ingredient	Container	Temp	Master Move
Pellet Hops	Vac-Mylar	Freezer (-18°C)	Purge with $CO_2$. Freezer storage slows alpha-acid decay by 90%.
Base Malt	HDPE/Steel Bin	10°C (Stable)	Keep off concrete. Moisture wicking leads to "stale grain" aldehydes.
Milled Grain	Vac Bag	Fridge (4°C)	Milling exposes starches to $O_2$. Use desiccant packs to prevent clumping.
Dry Yeast	Foil/Jar	Fridge (2°C)	Reseal with tape; store in a dark jar. Rehydrate to prove viability.

Technical Deep Dives

Advanced Ingredient Protection

Hop Storage That Preserves Punch

Hops are the most fragile ingredient in the Master's Pantry. Once opened, pellets lose alpha acids and essential oils rapidly. If you store them warm, the resins oxidize into isovaleric acid—giving your beer a "dirty sock" aroma. Use Mylar bags as they provide a complete oxygen barrier that standard thin-film zipper bags lack.

The Freezer Rule: Use a dedicated chest freezer. Frost-free upright freezers cycle their internal temperature to prevent ice buildup, which causes internal condensation inside your hop bags, leading to ice crystals and terpene degradation.

Grain Storage That Stays Crisp

Whole malt kernel husks provide a natural protection for the starches inside. However, once grain is milled, the surface area increases by a factor of 1000, exposing starches and lipids to oxidation. This leads to starch retrogradation—where the starches become less soluble and harder for enzymes to convert in the mash.

Pest & Moisture Protocol: Steel cans with clamp lids block grain moths and mice. Add a food-safe desiccant canister to the bin to keep the grain below 5% moisture. If grain smells "papery" or flat, it's already past its peak integrity.

Master Brewer Pro Tips

Efficiency & Organization

• Batch-Sized Hop Kits: When you buy bulk hops, immediately split them into pre-weighed vacuum packs for specific addition times (e.g., 60m, 10m, Whirlpool). This prevents multiple oxygen exposures for the same lot.
• The $CO_2$ "Burp": If you are using Mason jars for grain or hops, use your kegging setup to inject a short burst of $CO_2$ into the jar before sealing. $CO_2$ is heavier than air and will displace the oxygen at the bottom.
• Desiccant Regeneration: Use rechargeable silica gel cans in your grain bins. When they turn pink, bake them in the oven at 120°C until they turn blue again. Dry grain is efficient grain.
• Labeling Discipline: Use a Sharpie and painter's tape. Never rely on memory. Label variety, AA%, harvest year, and the date YOU opened it. The oldest stock must be used first.

Wrap Up

Protect your inputs and your beer will pay you back. Keep it cool, dark, and dry. Track your dates and rotate like a pro. You will taste the difference in every pour.

Cheers to sharper hops, cleaner malt, and yeast that shows up ready to work.

What effect do hops have on beer?

What are hops and what do they do to beer?

Hops are what makes beer taste wonderful!

At their most basic form, hops are the cone-shaped flower of the plant known as 'Humulus lupulus'. 

Hops may be added to the beer wort to impart a bitterness which balances the sweet malt flavour of beer.

Hops can be used to create a variety of tastes and to offer unique aromas which enhance the drinking experience. 

Beer makers of the last millennium recognized that hops were a crucial element of brewing good beer. It was the Germans who were amongst the first beer makers to recognize their needs. So much so, it became the law that only hops could be used in beer as opposed to another beer flavoring such as anise (aniseed), heather and rosewood. 

The beauty of the hops plant is that its varieties give different qualities to the beer, meaning there are so many opportunities for making brewing discoveries.

The climate and location of where the hops are grown help determine these qualities but most importantly, the alpha or beta acids of the hop cause the greatest contribution. 

Hops also offer the ability to act as a stability agent, preventing spoilage of the beer (hence Indian Pale Ales shipped to India from Great Britain were heavily hopped). Its properties allow the beer yeast to thrive over any other potential contaminants.

It also helps with head retention and acts as a natural clarifier agent.

Hops also contain oils which add to the flavour. Hops can be added at different points in the brewing process and the differing temperatures will also have an effect on those oils and flavour. 

A concept of a Jedi Knight brewing beer inside the belly of a giant worm

Hop associations with certain kinds of beers 

Certain kinds of hops are commonly associated with particular styles of beer or beer from certain regions.

Here's some common examples: 

• Pilsner beers have become nearly synonymous with the four popular 'noble hops' being the varieties of hop called Terrnanger, Spalt, Hallertauer and Saaz. Saaz hops in particular are associated with the brewing of lagers, most for the aroma that has become associated with the beer. Pilsner beers are known to traditionally come from the Czech Republic.
• The English Golding hop has become the signature hops of English ale. The Fuggle hop is another popular hop used for ale. 
• America has become a home for hop production and many new varieties from old favorites have been developed. American hops are recognized and appreciated all around the world for the bold, and often intense flavors they impart to beer. American hops are often described as being citrus-like, however that's a most rudimentary description.

Hops in pellet form

What form do hops come in for brewing?

Hops are traditionally distributed as pellets, plugs or whole leaf but they now can come in cyro hop form.

What hops should I use in my beer brewing? 

It of course depends on what kind of beer you are trying to make. If you are making beer clones or following recipes, you probably want to follow what other brewers have found to work well. 

Here's a list of some common hops that are often used by home brewers and ones I have used myself:

• Cascade: This is an extremely popular American hop. Known for its floral hop trait, it is often liked to a grapefruit. Cascade is known as a versatile hop variety that is popular for bittering, finishing and dry hopping of pale ale and American-style beers.
• Czech Saaz: as mentioned a popular hop for pilsner and lager style beers. Saaz offers a delicate, mild floral aroma.
• Green Bullet offers a traditional bittering quality and hop flavour. A Kauri-like giant of the New Zealand brewing industry this hop is closely associated with the world renowned Steinlager beer. Green bullets is best considered a bittering variety typically lager beers.
• Motueka Hops: Hey, I'm a Kiwi so why not promote a second Kiwi hops? The Moteuka hops comes from the region it is grown in, being the top of the South Island of New Zealand. Very suitable for more traditional style lagers, especially the increasingly popular Bohemian Pilsener
• Golding hops are good for bittering, finishing and dry hopping a range of ales

If you are a beginner brewer looking to use hops for the first time, we feel confident enough from our experience with using these hops that you won't go wrong -  as long as you match them to your intended style of beer.

We have a fond memory of a brew which used both cascade and green bullet hops to make a loosely approximate version of Steinlager.

It was a fine brew!

And so from that, you can take that it is OK to add different hops together to get different flavours and aromas!

When do I add hops to my beer?

Typically the beer wort is boiled with hops before it is cooled down to begin the fermentation process. The timings of when to add the hops in the boil can be critical as the different timings can cause the hops to work differently on the beer.

If you are making your own wort (as is, not using a beer kit) then it's best practice to follow a tried and true recipe, at least as you start out.

You can of course become more adventurous when you have a bit of confidence in your beer making skills!

If you're at that point you'll want to understand that the process is sometimes known as the “hop schedule”. A hop schedule will list the length of time that the hops should be in the boil, not the amount of time you should wait to add the hops.

This allows you to make your timings correctly. The rough guide is the longer you boil the hops, the more bitterness they will impart. The shorter you boil them, the more flavour will be added.

If you are using a simple beer kit, you have two choices when to add hops. You may add them when you bring all the ingredients of the kit together, or you can add them near the end of the fermentation process. The choice is yours, and in our experience, there doesn't appear to be much of a difference in the end result. 

Where can I buy quality hops?

Your local brewshop will typically have a wide selection but there are online stores everywhere, we recommend NZ's Brewshop but internationally you'll have some good luck buying on Amazon.

↠ How to stop cloudy home brew from happening

Cloudy beer can suck visually, but why does it happen? I did a batch of beer and nicely conditioned it and on pouring, it came about cloudier than usual.

It looked like a wheat beer that had been mixed with sawdust.

An imperfection.

Tasted alright though, but I wondered what had caused this to happen? Usually, my brews look deliciously golden...

• Was it because I made a mistake brewing?
• Did I get the temperature wrong?
• Was my yeast off?

Well, the truth is cloudy home brew beer is a common thing and it can occur for various reasons.

First up, as you are bottling your beer, you may notice that beer can be cloudy. This is a very normal part of the process as the beer hasn’t fully become beer yet.

As you bottle, you add some form of priming sugar. The residual yeast in the bottle will feed on that sugar and carbonation war occur. As the sugars are consumed by the yeast, the yeast will fall to the bottom of the bottle and the beer will go "clear".

You’ll obviously be able to tell this has happened as your beer will not be cloudy AND there will likely be some sediment at the bottom of the beer bottle.

Leaving the beer in the fermenter a bit longer than you might usually do so gives your beer time to clear even more.

By letting the yeast do its thing for a longer time, your beer will taste better too.

Do you know what the best trick is to avoid cloudy beer is? 

Cold crashing.

Chilling your beer in a fridge at the end of fermentation will cause yeast to fall to the bottom giving you greatly improved clarity. The short version of cold crashing is that you place the whole 23 litre fermenting drum into a pretty cold fridge and you leave it for several days to allow the cold to do its thing.

You can then bottle or keg in the normal manner.

Conditioning beer is very important

A careful pour from the bottle will usually avoid stirring up the sediment which causes a cloudy glass of beer. 

This is especially so if you have got a perfect level of carbonation – an over-sugared beer means more bubbles which increases the chance of the sediment being stirred up into your pour.

If opening your beer causes the beer to go cloudy because the bubbles stir the sediment up too much, I've found cooling the beer in a fridge for 24 hours can help prevent this quite well.

You can also use finings to 'clear' your beer of unwanted proteins what can also cause cloudiness.

Cooling and refrigeration

One of the reasons why beer does go cloudy is due to improper refrigeration timings and techniques.

The process of storing beer is called laagering (sounds like lager eh?). Lagers are lagers because they are best stored cold.

Nordic Vikings learned this method years ago when they laagered their beer barrels in cold caves over the winter or something...

Refrigeration of storing beer in a cool place helps to clear beer rapidly.

The science behind this is at lower temperatures it is more difficult for the yeast, tannins and proteins in the beer to remain suspended.

Cold stored beer will clear much more rapidly than beer stored at a normal room temperature.

If you intend to lager your beer you must wait until carbonation has occurred. If you cool your beer too soon, you run the risk of disrupting the yeast from its secondary fermentation process and carbonation may not occur (or it will be very slow to do so).

Fining agents can reduce cloudiness

A number of fining agents can be added to the finished beer that will aid in clearing the beer quickly.

These agents work by attaching themselves to the yeast, tannins, and proteins to help them precipitate to the bottom of your fermenter or bottle more quickly.

Plain gelatin can be used quite well. Dissolve it in warm sterile water and add it to your fermenter a few days before bottling.

Polyclar is also a popular product to use.

I also have a sneaky suspicion that gelatin in jelly beans also works to help clear the beer.

Chill haze and the 'cold break'

You may have heard of ‘chill haze’. This is a really common cause of beer cloudiness where the wort has been boiled and the cooling process has not generated enough ‘cold break’. 

The cold break is the proteins from the beer that are precipitated to the bottom of the beer by the cold temperature.

Using a copper wort chiller allows for an effective way to get more cold break forming and thus reduces the chance of chill haze in your finished beer.

German wheat beers are often cloudy and that's just the way it is

If you are making a German style wheat beer, it is natural for a wheat beer to have an element of cloudiness.

Some beers, like German Hefeweizens, use yeasts and ingredients that make the beer cloudy no matter what you do.

So how do the big breweries avoid producing cloudy beer?

It’s a simple trick.

Commercial brewers (including craft beer breweries)  filter their beer.

From it, they take all the live yeast and basically bottle a “lifeless” product. The beer you homebrew and drink still contains live yeast so there’s a much more likelihood of a cloudy home brew happening.

Beer like Steinlager that you buy from commercial brewers (and even craft beer breweries) will have been filtered.

Another handy trick that the home brewer can do to improve their beer is to use a fining agent. 

The agent is usually a form of gelatin or moss (!) and it binds to the yeast and other particles in the beer and drags them down to the bottom of the beer to take their grave as sediment.

Sugar 

Make sure that you do not over sugar your beers. If you do, you run the risk of extra fizzy beer or gushers which can clearly upset the sediment.

A cloudy beer isn’t the end of the world but hopefully, this will give a little insight into why your beer is cloudy and how you can try to clear it up the next time that you brew.
