Ever wondered if brewing your own Coopers Iconic Lager could be as simple and rewarding as enjoying a perfectly chilled bottle? The truth is, with the right guidance, transforming a simple Coopers homebrew kit into a customized, delicious batch of beer is not only achievable but also incredibly cost-effective. As highlighted in the video above, diving into homebrewing Coopers Lager can lead to surprising discoveries, rich flavors, and a deep sense of satisfaction.
For many aspiring brewers, the thought of making their own beer can seem daunting. Yet, the process, especially with a quality kit like Coopers, is designed to be accessible. This post will expand on the insights and step-by-step instructions from the video, guiding you through customizing your Coopers Lager with specific enhancements, ensuring proper sanitation, and mastering the bottling process for a truly exceptional brew.
The Enduring Quality of Coopers Lager: A Story of Time and Taste
A remarkable aspect of Coopers beers, as eloquently shared in the video, is their ability to improve significantly with age. This isn’t just anecdotal; it’s a testament to the quality of the brew. A particular story stands out: a bottle of Coopers Lager, 13 years old, was recently tasted and described as “amazing.” This incredible longevity challenges common perceptions about homebrewed beer, revealing that with proper storage, a Coopers brew can evolve into something extraordinary.
Before sharing this captivating story, our host, Moussa, prudently contacted Coopers directly. Frank from Coopers confirmed that drinking 13-year-old Coopers beers poses no danger. At worst, they might oxidize and simply not taste good. This assurance is invaluable for homebrewers who might wonder about the shelf life of their creations. It means that not only can you enjoy your Coopers Lager fresh, but you can also confidently set aside a few bottles to discover how their flavors develop over months, or even years, becoming a truly unique vintage.
Customizing Your Coopers Lager: A Step-by-Step Enhancement Guide
While the Coopers kit provides an excellent foundation, the real fun in homebrewing often comes from personalizing your brew. In the video, Moussa demonstrates how to infuse a Coopers Lager with distinctive characteristics, transforming it into a beer reminiscent of commercial favorites like James Squire 150 lashes. This customization involves three key additions:
- Galaxy Hops: These Australian hops are renowned for their intensely fruity and citrusy aroma, making them perfect for infusions. Despite their high alpha percentage, up to 16%, they are used here purely for flavor and aroma, not for bitterness.
- SafAle S-04 Yeast: This specific yeast strain is a popular choice for English ales but also lends a delightful fruity character to lagers. It has a broad fermentation temperature range, typically 18 to 26 degrees Celsius, offering flexibility for homebrewers.
- Light Dry Malt: Adding half a kilo of light dry malt not only enhances the sweetness of the lager but also contributes to a richer, more stable head on the beer.
Preparing Your Brewing Environment: Sanitation is King
The cardinal rule of homebrewing is sanitation. Bacteria and wild yeasts are everywhere, invisible to the naked eye, and can quickly ruin a batch. The video meticulously demonstrates the sterilization and sanitization process for the fermenter and later, the bottles. Here’s a breakdown:
For a brand new kit, sanitization is usually sufficient. However, after your first batch, full sterilization becomes critical. Never use soap on brewing equipment, as residue can drastically affect beer flavor and fermentation. Instead, wash everything with hot water and then follow with specific cleaning agents.
Sterilization
For sterilization, chlorinated trisodium phosphate is recommended. The guideline is one teaspoon per liter of hot water. For a typical fermenter, approximately two liters of this solution should be used to thoroughly wash all surfaces, including the fermenter body, lid, and even brewing spoons. It’s a three-part system: sleeve, lid, and main body, all requiring diligent cleaning.
Sanitization
After sterilization and rinsing with cold water, sanitization is the final, crucial step. Phosphoric acid, a food-grade sanitizer, is sprayed onto all surfaces that will contact the beer. The key here is that phosphoric acid does not need to be rinsed off; it simply drips dry, leaving no harmful residue but ensuring a sterile environment.
Another popular sanitizer, often used by experienced brewers, is StellarSan or Star San. These “no-rinse” sanitizers are highly effective and widely trusted for their ability to quickly sanitize surfaces without leaving flavor-affecting residues, provided they are used at the correct dilution.
The Coopers Lager Brewing Process: From Syrup to Fermentation
With your environment impeccably clean, the actual brewing can begin. This process requires precision and patience, transforming raw ingredients into the base for your beer.
Softening the Syrup and Preparing Hops
The Coopers syrup tin needs to be softened by placing it in boiling water for approximately 20 minutes. Simultaneously, the Galaxy hops, pre-packaged in a “teabag” for infusion, are steeped in a cup of boiling water for 10 to 20 minutes to extract their aromatic compounds.
Mixing the Brew
Pour about one to two liters of boiling water into the sanitized fermenter. The softened Coopers syrup is then added, using the remaining hot water to rinse out any syrup left in the tin. Next, slowly add Coopers Enhancer Number Two, a blend of malt, dextrose, and maltodextrin. Following this, the half a kilo of light dry malt is gradually incorporated, contributing to a sweeter profile and better head retention.
Once these ingredients are mixed, tap water is added to reach the desired volume. High-quality tap water is often sufficient, providing natural oxygenation for the yeast. Brewers who make their beer from grain typically need to introduce oxygen separately, but for kit brewing, this step is usually not necessary.
Pitching the Yeast and Fermentation
Before adding the yeast, the temperature of the brew must drop. The ideal pitching temperature for SafAle S-04 yeast is between 18 and 26 degrees Celsius. Moussa’s brew was pitched at 25 degrees, a beautiful drop from an initial 26 degrees. Before pitching, a hydrometer reading is taken to determine the Original Specific Gravity (OG). Coopers typically aims for an OG of 1038, but with the added light dry malt, this modified brew registered a higher 1042, indicating a greater potential alcohol content. The sample taken for the hydrometer reading should never be returned to the fermenter; it’s best enjoyed as a pre-fermentation taste.
Just before pitching the yeast, the steeped Galaxy hops are added to the fermenter. Finally, the SafAle S-04 yeast is lightly sprinkled onto the surface of the brew and not stirred in. The lid is then securely fastened with clips. Coopers generally recommends a fermentation period of six days, but Moussa prefers eight days to allow for a more thorough settling. Throughout this period, temperature control is vital. If the temperature rises, move the fermenter to a cooler spot. If it drops too low, use a heat mat, like the effective Morgan brand heat pad, or a blanket to maintain the optimal range.
Bottling Your Coopers Lager: The Final Steps to Carbonation
After approximately eight days, once the specific gravity has stabilized for a couple of days (as confirmed by hydrometer readings), the Coopers Lager is ready for bottling. The fermentation temperature on bottling day, around 23 degrees Celsius, falls perfectly within the 18 to 26 degrees Celsius range for SafAle S-04 yeast.
Calculating Alcohol Content
Taking a final specific gravity (FG) reading is essential. This brew stabilized at 1009. Using Coopers’ chart, an OG of 1042 and an FG of 1009 translates to roughly a 4.3% potential alcohol level. During the secondary fermentation in the bottle, this will increase by about 0.5%, bringing the final alcohol content to approximately 4.8%. This calculation allows homebrewers to understand the strength of their creation.
Sterilizing and Sanitizing Bottles
Just like with the fermenter, bottles require thorough sterilization and sanitization. The video showcases a highly efficient bottle washer, imported from Italy and available from Country Brewer. This device cleans bottles better than manual washing, pumping hot water and chlorinated trisodium phosphate (one spoon per liter) to clean every surface. After a hot wash, the bottles are rinsed with cold water.
For sanitization, phosphoric acid is again used, sprayed into each bottle. Since it’s a no-rinse sanitizer, the bottles are then placed on a bottle tree, such as the Morgan’s model that holds 81 bottles (eight removable holders for 10 bottles each, plus one on top), allowing them to drip dry without reintroducing contaminants.
Filling and Carbonating
Before filling, ensure the fermenter lid is slightly loosened to release pressure. A special little bottler with a valve is used to fill the bottles from the fermenter tap. As the bottle pushes against the valve, the beer flows in. It’s normal for the first few bottles to froth up a bit; letting them overflow slightly can help manage this. It’s crucial to minimize the brew’s exposure to the environment.
Once filled, two Coopers carbonation drops are added to each 750ml or 740ml bottle (one drop for 375ml bottles). These drops facilitate the secondary fermentation process, creating the desired carbonation. The bottle caps must then be closed very tightly to prevent air from escaping, which would result in flat beer. As the fermenter empties, it will need to be tilted carefully to collect the remaining brew without disturbing the sediment at the bottom.
Enjoying Your Coopers Lager and Beyond
Your custom Coopers Iconic Lager is typically ready to drink in about three weeks. However, much like the 13-year-old lager story, patience often yields superior results. Many homebrewers, including Moussa, find that their Coopers brews taste best after two and a half to three months. To keep track of your brewing journey, it’s an excellent habit to log the type of brew, any additions made, and the date it was brewed. This provides a valuable reference for future batches and helps you replicate successes.
It’s also worth noting that Coopers beers are GMO-free and come with a “best after” date, indicating their robust quality. Homebrewing offers an incredible opportunity to experiment, refine your craft, and create unique beverages. By following meticulous practices for cleanliness, understanding your ingredients, and carefully monitoring your brew, you can consistently produce high-quality Coopers Lager that not only meets but often exceeds expectations, rivaling your favorite commercial beers.
