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.

In this discussion, we will delve into the use of Bentonite as a clarifying agent when making wine, exploring its properties, application techniques, and the impact it has on the final product's clarity and sensory attributes.

Bentonite is a clay mineral with unique properties that make it well-suited for wine clarification. It consists mainly of montmorillonite, which possesses a high surface area and a negative electrical charge. These characteristics enable Bentonite to attract and bind with positively charged particles, including proteins, haze-causing compounds, and certain polyphenols.

Bentonite is typically applied in the form of a fining agent. It can be added during different stages of winemaking, such as after fermentation or during aging, depending on the desired outcome. The dosage of Bentonite may vary based on factors like grape variety, pH levels, and the initial turbidity of the wine. It is crucial to follow recommended dosage guidelines and conduct small-scale trials to determine the optimal dosage for each specific wine.

When Bentonite is introduced into the wine, it forms a gel-like substance that settles at the bottom of the container over time. This gel acts as a binding agent, attracting and capturing suspended particles, proteins, and tannins responsible for haze formation. As the Bentonite settles, it takes along the captured particles, leaving the wine clearer and more visually appealing.

Bentonite plays a significant role in enhancing wine clarity. By removing proteins, tannins, and other haze-causing compounds, it contributes to a visually stunning and brilliantly clear wine. The removal of these substances also has an impact on the wine's sensory attributes. Bentonite can reduce astringency, bitterness, and unwanted flavors associated with certain proteins and tannins, resulting in a smoother, more balanced wine with improved aroma and flavor clarity.

While Bentonite offers many advantages, it is essential to consider certain factors and limitations. Bentonite can remove not only unwanted proteins but also desirable aroma and flavor compounds. Over-fining is a potential risk if excessive Bentonite is used, leading to a loss of desired complexity and character. Additionally, Bentonite may have limited effectiveness in reducing certain tannins and other complex compounds, requiring the consideration of alternative fining agents or techniques in specific winemaking situations.

In certain winemaking scenarios, Sparkolloid can be used in tandem with Bentonite to achieve even greater clarity and stability in wines. While Bentonite is effective in removing proteins and certain haze-causing compounds, Sparkolloid, as an additional fining agent, can target other problematic particles such as tannins. 

By combining the unique properties of both fining agents, winemakers can address a broader range of clarity concerns and ensure a more comprehensive fining process. When using Sparkolloid in conjunction with Bentonite, it is crucial to carefully adjust the dosages of each agent to maintain a balance and avoid over-fining. 

Small-scale trials and monitoring the settling process can help determine the optimal ratio and timing for the dual application. The complementary actions of Sparkolloid and Bentonite can synergistically enhance wine clarity, stability, and sensory attributes, resulting in wines of exceptional quality and visual appeal.

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.

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.
