Preparation

Selecting ripe and flavorful feijoas is crucial to ensure the best quality and taste in your feijoa wine. Here's why it's important:

Feijoas that are fully ripe will offer the best balance of flavors, sweetness, and acidity. Look for fruits that are slightly soft to the touch and have a pleasant fragrance. Avoid using overly ripe or underripe feijoas, as they may affect the overall taste of the wine.

Before beginning the winemaking process, it is essential to clean and sanitize all equipment thoroughly. This step is crucial to prevent the growth of unwanted bacteria or wild yeasts that could negatively impact the wine's flavor and quality. Follow these steps for cleaning and sanitizing your equipment:

1. Start by washing all equipment, including the fermentation vessel, airlock, siphoning tube, hydrometer, bottles, and corks, with warm water and a mild detergent. Use a brush or sponge to remove any visible dirt or residue.

2. Rinse the equipment thoroughly to ensure no detergent or soap residue remains.

3. Prepare a sanitizing solution by following the instructions provided with the chosen sanitizer. Common sanitizing agents include metabisulfite, bleach, or a commercial brewing sanitizer.

4. Submerge all equipment in the sanitizing solution, ensuring that they are fully covered. Allow them to soak for the recommended amount of time specified by the sanitizer's instructions.

5. After sanitizing, rinse the equipment with clean, cold water. Avoid touching the sanitized surfaces with your hands or any non-sanitized objects.

Now that the equipment is clean and sanitized, you can proceed with washing and preparing the feijoas for winemaking. Follow these steps:

1. Start by rinsing the feijoas under cool running water to remove any dirt or debris.

2. Once cleaned, remove the skin from the feijoas. This can be done by cutting off the stem end and gently peeling the skin away with a paring knife or your fingers. Alternatively, you can scoop out the pulp from the skin using a spoon.

3. After peeling, chop the feijoas into small pieces, roughly 1 to 2 centimeters in size. This will facilitate the extraction of flavors during the fermentation process. Remove any tough or woody parts, as they can affect the texture and taste of the wine.

Making wine or beer is like painting, most of the work is in the preparation so we strongly urge you to follow sensible santitization practices - there's nothing worse than checking on a batch or brew to find it spoiled. It's simply a waste of your time and money if you do not clean and sterilize equipment!

Fermentation

The fermentation process is where the magic happens, as the yeast converts the sugars in the feijoas into alcohol. Follow these steps to ensure a successful fermentation:


1. Mashing the feijoas: Place the chopped feijoas into a sanitized container and mash them using a sanitized utensil, such as a potato masher or a sanitized gloved hand. This step helps release the juices and flavors from the fruit.

2. Adding sugar and water to the fermentation vessel: Transfer the mashed feijoas into a sanitized fermentation vessel, then add the required amount of sugar and water. The sugar provides the necessary fuel for yeast fermentation. The amount of sugar required will depend on the desired sweetness and alcohol content of the wine. Refer to a feijoa wine recipe or use a hydrometer to measure the specific gravity and adjust the sugar accordingly.

3. Mixing the ingredients well: Stir the mixture thoroughly to dissolve the sugar and ensure even distribution of the feijoa pulp. This helps kickstart the fermentation process and promotes yeast activity.

4. Adding yeast and stirring: Sprinkle the wine yeast over the surface of the mixture. Give it a gentle stir to incorporate the yeast into the liquid. This initiates fermentation by introducing the yeast that will convert the sugars into alcohol.

5. Sealing the vessel with an airlock: Attach a sanitized airlock to the fermentation vessel according to the manufacturer's instructions. The airlock allows carbon dioxide to escape while preventing oxygen and contaminants from entering. Place the vessel in a cool, dark area with a stable temperature.

Ideal temperature and conditions for fermentation:

The ideal temperature for feijoa wine fermentation is generally between 18°C and 24°C (64°F and 75°F). Avoid exposing the fermentation vessel to extreme temperature fluctuations or direct sunlight, as these factors can affect the fermentation process and the quality of the wine. Aim for a consistent temperature throughout the fermentation period.

Monitoring the fermentation process:

During fermentation, it's important to monitor the progress regularly. Here are a few key points to keep in mind:

- Check the airlock: The airlock should show signs of fermentation within the first 24 to 48 hours, such as bubbles or movement in the airlock. This indicates that the yeast is active.

- Take hydrometer readings: Use a sanitized hydrometer to measure the specific gravity of the wine. Take readings periodically to track the fermentation progress. As fermentation continues, the specific gravity will decrease, indicating that the sugar is being converted into alcohol.

- Observe the aroma and appearance: Throughout fermentation, pay attention to any unusual odors or off-putting aromas. Additionally, monitor the color and clarity of the liquid, as these can indicate the progress of fermentation.

Duration of fermentation and signs of completion:

Feijoa wine fermentation typically lasts for around 2 to 4 weeks, but it can vary depending on various factors, such as temperature and yeast activity. Signs of completion include a stable specific gravity reading over several days, no visible fermentation activity in the airlock, and a clearer appearance. Once fermentation is complete, the wine is ready for the next steps, such as racking and aging.

What is the best yeast to use to make feijoa wine?

When making feijoa wine, it is recommended to use a wine yeast specifically formulated for fruit wines. While there are various types of wine yeast available, certain strains are better suited for fermenting fruit-based wines, including feijoa wine. Two popular choices are Lalvin EC-1118 (also known as Prise de Mousse) and Lalvin QA23.

Lalvin EC-1118 is a champagne yeast known for its ability to tolerate a wide range of temperatures and produce a clean, neutral fermentation. It has a strong fermentation capacity and is well-suited for fruit wines, including feijoa wine. This yeast can help ensure a complete fermentation and produce a dry wine with a crisp character.

Lalvin QA23 is another excellent option for making feijoa wine. It is known for its low nutrient requirements and ability to enhance fruit flavors. QA23 can contribute to the development of pleasant aromas and help preserve the natural characteristics of the feijoas. This yeast strain is often chosen for white wines and fruit wines, including those made with feijoas.

Both Lalvin EC-1118 and Lalvin QA23 are reliable choices for feijoa wine, but the final selection depends on personal preference and desired outcomes. Other wine yeast strains suitable for fruit wines may also be available, so it's worth exploring different options and consulting with local winemaking suppliers or enthusiasts for recommendations specific to your region and the available yeast strains.

Racking and Aging

Racking is an essential step in winemaking that involves transferring the wine from one vessel to another, leaving behind sediment and clarifying the wine. Here's what you need to know:

Process of racking:

1. Prepare a clean and sanitized secondary fermentation vessel. This can be another fermentation vessel or a carboy.

2. Gently siphon the feijoa wine from the primary fermentation vessel into the secondary vessel. The siphoning tube should reach near the bottom of the vessel to minimize oxygen exposure.

3. As you transfer the wine, be cautious not to disturb the sediment at the bottom. This sediment consists of yeast, fruit solids, and other particles that have settled during fermentation.

4. Once the wine has been successfully racked, attach a sanitized airlock to the secondary vessel.

Purpose of racking and its importance in clarifying the wine:

Racking serves two primary purposes: clarifying the wine and separating it from the sediment. During fermentation, solids and suspended particles settle at the bottom of the vessel, clouding the wine. Racking helps remove these impurities, resulting in a clearer and more visually appealing wine. Additionally, it reduces the risk of off-flavors caused by extended contact with the sediment.

Instructions for racking the wine and leaving behind sediment:

To rack the wine while leaving behind sediment:

1. Place the primary fermentation vessel on a stable surface and ensure it is higher than the secondary vessel.

2. Insert the sanitized siphoning tube into the wine, making sure it reaches below the surface but does not touch the sediment at the bottom.

3. Start the siphoning process by either using a gravity siphon or by gently sucking on the tube to initiate the flow. Be careful not to introduce any contaminants into the wine.

4. Direct the flow of wine into the secondary vessel, gradually raising the primary vessel if needed to maintain the siphoning process.

5. Monitor the process and stop siphoning when you notice the sediment approaching the tube's opening. This ensures that only the clarified wine is transferred.

What's the best time and way to store feijoa wine?

Aging feijoa wine allows it to develop and refine its flavors, aromas, and overall character. During this period, the wine undergoes chemical changes that contribute to its complexity and smoothness. While feijoa wine can be enjoyed relatively young, aging it can enhance its taste and texture.

The recommended aging period for feijoa wine can range from 6 months to 2 years, depending on personal preference and the wine's initial qualities. Generally, a minimum of 6 months is recommended to allow the flavors to meld and mellow. Longer aging periods can lead to further refinement and complexity.

Storage conditions for aging:

To properly age feijoa wine, consider the following storage conditions:

1. Temperature: Store the wine in a cool and stable environment, ideally between 12°C and 16°C (54°F and 61°F). Avoid temperature fluctuations, as they can affect the aging process and the wine's quality.

2. Light exposure: Keep the wine away from direct sunlight or strong artificial light, as UV rays can degrade the wine and negatively impact its flavors.

3. Humidity: Maintain a moderate level of humidity, around 60-70%, to prevent the corks from drying out and compromising the wine's seal.

4. Positioning: Store the bottles horizontally to keep the corks moist, ensuring a proper seal and minimizing the risk of oxidation.

By racking the wine and allowing it to age under appropriate conditions, you can enjoy the benefits of a clearer and more refined feijoa wine with enhanced flavors and aromas.

The maturation time for feijoa wine can vary depending on various factors, including personal preference, the wine's initial qualities, and the aging period it has already undergone. As a general guideline, it is recommended to allow the wine to mature for at least 3 to 6 months after bottling before consumption.

Making feijoa wine at home involves several steps, starting with the selection of ripe feijoas and the cleaning and sanitization of equipment. The feijoas are then prepared by removing the skin and chopping the fruit. The fermentation process begins by mashing the feijoas, adding sugar and water, and introducing yeast. The wine ferments in a controlled environment, and once fermentation is complete, it can be racked to clarify and separate it from sediment. The wine is aged in suitable conditions before being bottled and allowed to settle further. Finally, after a suitable maturation period, the feijoa wine is ready to be enjoyed.


Here are some final tips for achieving the best results:


1. Quality ingredients: Use ripe and flavorful feijoas to ensure the best taste in your wine.

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.

4. Cost-effective: By extending the shelf life of hops, vacuum sealing can help to reduce waste and save money in the long run. Brewers can buy hops in bulk and then seal them in smaller portions, which reduces the risk of spoilage and saves money on frequent trips to the store.

What are the best kind of bags to use with a vacuum sealer with hops?

When vacuum sealing hops, it's crucial to use the appropriate plastic bags that are specifically designed for food storage and vacuum sealing. Here are some of the best types of plastic bags to consider:

1. Vacuum sealer bags: These are bags specifically made for use with vacuum sealing machines. They are typically textured on one side to facilitate air extraction and have a smooth, airtight side for proper sealing. Vacuum sealer bags are often made from a combination of polyethylene (PE) and nylon (PA) materials. They are durable, puncture-resistant, and provide an excellent barrier against moisture and oxygen.

2. Embossed vacuum sealer rolls: These are rolls of plastic material used to create custom-sized bags for vacuum sealing. They work with vacuum sealer machines that have a built-in cutter to create bags of desired lengths. Embossed vacuum sealer rolls are similar to vacuum sealer bags, with one side textured for air extraction and the other side smooth for sealing. They offer flexibility in bag size and are suitable for sealing larger quantities of hops.

3. Mylar bags: Mylar bags, also known as foil bags or metalized bags, are made from a polyester film called BoPET (biaxially-oriented polyethylene terephthalate). These bags provide excellent oxygen and moisture barrier properties, making them a good option for long-term storage. Mylar bags are commonly used in the food industry for preserving freshness. However, they require heat sealing rather than vacuum sealing, so they are not suitable for use with standard vacuum sealing machines.

It's important to ensure that the plastic bags you choose are labeled as food-safe and specifically designed for vacuum sealing. They should be free from harmful chemicals and BPA. Additionally, select bags that are thick and durable to prevent punctures and leaks during storage.

When using vacuum sealer bags or rolls, follow the manufacturer's instructions for proper sealing and storage recommendations. Always leave enough headspace in the bag to accommodate the hops and allow for proper sealing. Label the bags with relevant information, such as the hop variety and date of sealing, for easy organization.

Overall, vacuum sealer bags and embossed rolls designed for use with vacuum sealing machines are the most recommended options for sealing hops, providing a reliable and effective packaging solution.

Using a vacuum sealer for hops in the context of beer brewing can have some practical considerations

Here are some important points to consider:

1. Hop pellet compatibility: Most vacuum sealers work best with solid items, such as hop pellets. Hop pellets are compressed hop cones that are commonly used in brewing. They are denser and easier to vacuum seal compared to whole cone hops, which can be bulkier and less suitable for vacuum sealing.

2. Proper packaging: It is essential to use appropriate packaging materials when vacuum sealing hops. Food-grade vacuum sealer bags or rolls are commonly used for this purpose. These bags are designed to withstand the vacuum sealing process and provide a barrier against moisture and oxygen. Ensure that the bags are sized appropriately for the amount of hops you want to seal, leaving enough headspace for effective sealing.

3. Pre-freezing considerations: Hops contain natural oils, which can cause the bags to be less airtight during the vacuum sealing process due to oil residue. To mitigate this issue, some brewers prefer to pre-freeze the hops for a short period before vacuum sealing. Freezing the hops helps to reduce the release of oils during the sealing process, leading to a tighter seal.

4. Vacuum sealing equipment: Choosing the right vacuum sealer is crucial. There are various types available, including handheld models and countertop machines. Consider factors such as budget, frequency of use, and sealing requirements when selecting a vacuum sealer. Look for models that offer adjustable sealing options and strong suction power to ensure a proper seal.

5. Storage considerations: Once the hops are vacuum sealed, it's important to store them properly. Keep the sealed bags in a cool, dark, and dry place, away from heat, sunlight, and moisture. A refrigerator or freezer can be an excellent storage option for maintaining the hops' freshness and preserving their aroma and flavor.

6. Labeling and organization: When vacuum sealing hops, it's helpful to label the bags with relevant information such as the hop variety, alpha acid percentage (if known), and date of sealing. This ensures proper organization and allows you to keep track of the hops' age and usage in your brewing process.

Remember that while vacuum sealing can help prolong the freshness of hops, it is still best to use them as fresh as possible for optimal flavor and aroma in your beer. Over time, even vacuum-sealed hops may experience some degradation in quality, so it's recommended to use them within a reasonable timeframe.

Guide to Proper Ingredient Storage: Keeping Hops, Grains, and Yeast Fresh

For seasoned homebrewers that are really getting into the swing and science of making beersies, they begin to become very cognisant that quality and freshness of ingredients play a crucial role in creating great-tasting beer. 

This ultimately leads to the understanding that proper storage of ingredients like hops, grains, and yeast is essential to maintain their freshness and preserve their flavors.

In this guide, we will explore effective techniques for storing these ingredients, including the use of airtight storage containers and vacuum sealers. By following these recommendations, you can ensure that your homebrewing ingredients remain at their best, resulting in exceptionally delicious brews.

1. Understanding Ingredient Storage Basics:

Before delving into specific storage methods, it's important to understand a few fundamentals of ingredient storage for home brewing:

Temperature Control: Keeping your ingredients stored at a cool and consistent temperature is vital for preserving their freshness. Fluctuations in temperature can lead to degradation and flavor loss. Aim for temperatures between 35°F and 50°F (2°C and 10°C), as this range helps slow down the process of oxidation and maintains the stability of the ingredients.

Protection from Light: Light exposure can be particularly harmful to hops, as it can cause them to lose their aroma and bitterness. Similarly, light can affect the quality of grains and yeast. To minimize light exposure, store your ingredients in opaque containers or in a dark area, such as a pantry or cellar (also beer does not enjoy being exposed to light).

Moisture can lead to spoilage and mold growth in ingredients like grains and yeast. Ensure your storage area is dry and free from excess humidity. Avoid storing ingredients in basements or areas prone to moisture. Additionally, use appropriate containers with airtight seals to keep ingredients dry and prevent moisture absorption.

2. Selecting Airtight Storage Containers:

Airtight storage containers are an excellent choice for storing your homebrewing ingredients. They help maintain freshness by keeping out air, light, and moisture. 

Here are some recommendations:

Food-Grade Plastic Containers: Choose containers made of food-grade plastic that are specifically designed for long-term storage. Look for containers with airtight seals and consider options with a UV-blocking feature for hop storage. Plastic containers are lightweight, durable, and provide an effective barrier against external elements.

Glass Jars: Glass jars with airtight lids can also be suitable for ingredient storage, especially for smaller quantities. Mason jars, for example, work well for storing hops. Glass containers are non-reactive and do not absorb odors or flavors, making them an excellent choice for preserving the integrity of the ingredients.

Metal Containers: For grains, consider metal containers such as stainless steel canisters or bins. Make sure they are airtight and have a seal to keep moisture out. Metal containers provide an additional layer of protection against light and can help preserve the freshness of the grains.

3. Utilizing Vacuum Sealers:

Vacuum sealers are an effective option for long-term ingredient storage, as they remove air and seal the bags tightly. Here's how to use them:

Invest in a Vacuum Sealer: Purchase a vacuum sealer specifically designed for home use. These devices come with vacuum bags or rolls, which allow you to customize the size of the bags according to your needs.

Bag Preparation: Cut the vacuum sealer bags or rolls to the desired size, leaving enough space for the ingredients. Ensure the bags are clean and dry before use to prevent contamination or moisture buildup.

Filling and Sealing: Place the ingredients in the bag, leaving some room for expansion. Insert the open end of the bag into the vacuum sealer and follow the manufacturer's instructions to remove the air and seal the bag. The vacuum sealer will create an airtight seal, removing the majority of the air from the bag and preventing oxygen exposure, which can lead to ingredient degradation.

Labeling and dating: Once the bags are sealed, it's important to label them with the type of ingredient and the date of packaging. This labeling system will help you keep track of the freshness of your ingredients and ensure you use them in a timely manner.

4. Additional Tips for Ingredient Storage:

Consider these supplementary tips to maximize ingredient freshness:

Purchase Fresh Ingredients: Start with fresh, high-quality ingredients to extend their shelf life. Check the packaging dates and opt for reputable suppliers to ensure you're working with the best possible ingredients.

Store Yeast Properly: Yeast is a sensitive ingredient that can be affected by temperature fluctuations. Check the specific storage requirements of the yeast strain you're using. In general, it's best to store yeast in the refrigerator, following the manufacturer's instructions. Keep it in a sealed container or airtight bag to prevent exposure to air and moisture.

Use Moisture Absorbing Packs: Including moisture-absorbing packs or desiccants in your storage containers can help minimize moisture buildup. These packs are designed to absorb excess moisture and maintain the dryness of the ingredients. They are particularly useful for grains, preventing spoilage and the growth of mold.

Rotate Your Stock: Practice FIFO (first in, first out) by using the oldest ingredients first and replenishing your stock regularly. By rotating your ingredients, you ensure that the freshest ingredients are used in your brews, minimizing the risk of using stale or expired ingredients.

Monitor Storage Conditions: Regularly check the storage area for any signs of issues such as moisture, pests, or temperature fluctuations. Address any problems promptly to maintain optimal ingredient freshness.

Proper storage of brewing ingredients is essential for maintaining their freshness and ensuring the quality of your homebrewed beer. By utilizing airtight storage containers and vacuum sealers, you can protect your hops, grains, and yeast from air, light, and moisture, preserving their flavors and aromas. 

Remember to follow the fundamental storage principles of temperature control, protection from light, and moisture prevention. With these storage techniques in place, you'll be well-equipped to create exceptional brews with the freshest ingredients available.

Cheers to your brewing success!

↠ 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.
