Those often demand much stricter temperature controls. Furthermore, Lallemand confirms it is not genetically modified. This assures purity for traditionalists. It delivers outstanding performance.
Traditional lager yeasts often pose challenges. Many produce sulfur compounds. This results in an undesirable “rotten egg” aroma. Diacetyl is another common concern. It can lead to buttery off-notes. Novalager yeast excels in this area. It produces extremely low diacetyl. Importantly, it generates no H2S (sulfur) whatsoever. This characteristic is present even during active fermentation. The result is a remarkably clean beer. This eliminates the need for long diacetyl rests. Such rests are usually crucial in traditional lager production. Brewers save valuable time and resources.
Novalager’s Performance: Outpacing Traditional Strains
The speed of Novalager yeast is truly impressive. It ferments much faster than typical lager strains. Some brewers report it even surpasses certain ale strains. The video illustrates this with clear data. At 12 degrees Celsius, Novalager completes fermentation quicker. It outperforms both Diamond lager yeast and Nottingham ale yeast. This efficiency is a huge benefit. Brewers can turn around batches much faster. This rapid action does not compromise quality. The resulting beer remains exceptionally clean. Its flavor profile is consistently excellent. This makes Novalager a top choice. It is ideal for brewers seeking efficiency.
The elimination of H2S production is another key benefit. The provided diagram vividly demonstrates this point. Novalager shows non-existent H2S levels. This contrasts with other yeast strains. Other yeasts often produce significant amounts. This trait is particularly appealing. It addresses a common pain point for lager brewers. Avoiding sulfur off-flavors is a significant advantage. This ensures a purer aroma and taste. Consequently, it elevates the overall beer quality.
The IPL Experiment: A Practical Case Study with Zamba Hops
The video showcases a specific brewing project. An India Pale Lager (IPL) was created. This beer aimed for a “New Zealand style lager.” It featured a hoppy and flavorful profile. The brewer utilized a simple grain bill. Joe White Signature Ale Malt formed the base. This was generously supplied by Bintani. Additionally, 500 grams of Munich malt were included. Another 500 grams of oats contributed to the body. This combination laid a solid foundation. It provided a rich, malty backbone. The oats also added a silky mouthfeel. These ingredients created a complex base. This supports the vibrant hop character.
Mash parameters were carefully controlled. The brewer executed a single infusion mash. It was held at 65° C (149° F) for 75 minutes. This duration ensures optimal sugar extraction. A mash out followed for 10 minutes. This occurred at 76° C. Sparging was performed with 15.5 liters of water. This process maximizes fermentable sugars. The target original gravity was 1.050. The actual result was a slightly higher 1.053. This indicates efficient sugar conversion. The brewing process was meticulous. Every step contributed to the final product. The base recipe was thoughtfully designed.
Hop Selection and Scheduling for a Distinctive IPL
The IPL received a dynamic hop treatment. Bintani supplied the chosen hops. Bitterness was established with Select Spalt hops. 25 grams were added at 60 minutes. This provides a clean, classic hop bitterness. Zamba hops were introduced late in the boil. 25 grams went in at 1 minute. A hop stand followed at 95° C. Another 25 grams of Zamba were added for 20 minutes. This technique extracts maximum aroma. It also enhances flavor compounds. Finally, a significant dry hop addition occurred. 50 grams of Zamba hops were used for dry hopping. This amplifies the tropical and fruity notes. The hop schedule was complex. It aimed for a multi-layered hop experience. The Zamba hop profile delivered unique characteristics.
The brewer chose a relatively conservative amount of Zamba. This allowed for proper evaluation. He tested these new hops carefully. Previous experiences advised against excessive initial use. Learning from past batches is key. A cautious approach helps understand hop impact. Dry hopping amplifies the aroma further. The total Zamba usage creates a complex profile. It blends bitterness with vibrant tropical notes. This yields a distinctive New Zealand style IPL. The hop choices were strategic. They built a nuanced and aromatic beer.
Novalager in Action: A Rapid Fermentation Case Study
The brewing day concluded with no-chilling. The wort was transferred to a cube. It was allowed to cool naturally overnight. The next day, 20 grams of Novalager yeast were pitched. This amount was used for a 6-gallon batch. This quantity is notably efficient. It contrasts with traditional lager yeast requirements. Brewers often use multiple packs. Sometimes, three or four packets are necessary. Novalager requires far less yeast. This is another cost and resource saving. The yeast was pitched into the fermenter. A spunding valve was then attached. This allowed for pressure fermentation. The initial fermentation temperature was set at 15°C. This slightly warmer pitch helps yeast activation. It facilitates a strong start.
The fermentation kinetics were extraordinary. By October 18th (10 PM), the starting gravity was 1.053. Just two days later, on October 20th, gravity had dropped to 1.025. This rapid progress is astounding. At this point, the temperature was bumped. It increased by 2 degrees to 16°C. This practice helps yeast finish strong. It also prevents any potential sluggishness. The final gravity was reached by October 22nd (7:02 AM). This indicates a complete fermentation. The entire process from pitching to final gravity took only four days. This timeline is unprecedented for lagers. It truly showcases Novalager’s efficiency.
Pressure fermentation played a role in this success. The spunding valve was set to 5 PSI. This moderate pressure has several benefits. It can suppress ester production. It also improves head retention. The brewer confirmed no ester issues. He stated that pressures under 15 PSI are generally safe. This method allows for faster fermentation. It often results in cleaner profiles. The use of a RAPT Pill monitored fermentation. This tool provides accurate internal temperature readings. It ensured precise control. The combination of Novalager and pressure fermentation delivered outstanding results. It produced a clean, rapid lager.
Post-Fermentation and Flavor Profile
Following primary fermentation, dry hopping occurred. The brewer pulled the fermenter from the fridge. He added 50 grams of Zamba hops. This was done using a hop bong. The hops were flushed with CO2. This technique prevents oxidation. It helps preserve hop aroma. The beer sat for a few days. This allowed hop compounds to infuse. Afterward, it was returned to the fridge. It underwent crash chilling. This process clarifies the beer. It also helps settle yeast and hop particulates. Subsequently, the beer was kegged. Remarkably, no dedicated lagering time was required. The entire brewing process, from pitch to keg, took less than a week. This rapid turnaround is a key advantage.
The final beer exhibited classic lager qualities. It possessed a desirable crispness. A characteristic dryness was also present. Importantly, there was no sulfur aroma. No other off-flavors marred the profile. The beer was clean and refreshing. This proves Novalager’s ability. It delivers quality lagers quickly. The brewer also noted observations from a conference. Two Novalager beers were tasted there. One fermented at 10 degrees. The other was fermented at 20 degrees. The 10-degree sample showed some fruitiness. This was an unexpected outcome. Typically, hotter temperatures produce more esters. This variation suggests Novalager’s versatility. It adapts well to different fermentation strategies. Brewers can experiment with temperature. This allows for diverse flavor expressions.
