The world of homebrewing is consistently evolving, and a significant advancement for lager enthusiasts has recently emerged: the NovaLager yeast. As observed in the video above, this innovative hybrid strain promises to revolutionize how lagers are brewed at home, offering unprecedented speed, cleanliness, and flexibility without compromising the classic lager profile.
Traditional lager brewing has long been associated with extended fermentation times and meticulous temperature control. However, a new era is being introduced with NovaLager, which facilitates the production of crisp, clean lagers in a fraction of the time. This yeast is quickly gaining recognition for its ability to deliver results that were previously challenging for many homebrewers.
Understanding NovaLager Yeast: A Hybrid Innovation
NovaLager yeast is not simply another bottom-fermenting strain; rather, it is described as a true hybrid lager yeast. This unique characteristic allows it to operate with a much broader temperature range than typical lager yeasts, extending from 10 to 20 degrees Celsius (50-68°F).
Imagine if a brewer could ferment a lager at temperatures closer to those used for ales, yet still achieve the desired clean profile. This becomes a reality with NovaLager. While it is not genetically modified, its enhanced performance allows for faster fermentation, often surpassing the speed of some ale strains.
Rapid Fermentation: Speeding Up Your Brewing Schedule
One of the most compelling benefits of NovaLager yeast, as highlighted in the accompanying video, is its incredible speed. It is observed that a batch of lager can be fermented in just a few days, a stark contrast to the weeks or even months typically required for traditional lager strains.
For instance, an initial gravity of 1.053 was reported to drop to 1.025 in just two days when fermented at 14 degrees Celsius. Final gravity was reached in a mere four days, meaning a finished beer could be ready for kegging or bottling in less than a week. This efficiency dramatically reduces the time commitment often associated with crafting high-quality lagers.
Eliminating Off-Flavors: The Clean Lager Experience
A common challenge with traditional lager yeasts, especially when fermented warmer or faster, is the production of undesirable off-flavors. Sulfur compounds, particularly hydrogen sulfide (H2S), often manifest as a rotten egg smell, requiring extensive lagering periods to dissipate. Diacetyl, another common byproduct, can impart a buttery or butterscotch flavor that is generally unwanted in a clean lager.
In contrast, NovaLager yeast is reported to produce virtually no sulfur whatsoever, even during active fermentation. Diagrammatic evidence presented in the video indicates nonexistent H2S production compared to other well-known strains like Diamond and Nottingham. Furthermore, exceptionally low levels of diacetyl are achieved, allowing brewers to bypass or significantly shorten traditional diacetyl rests. This means a cleaner, crisper beer with less effort and time.
Brewing with NovaLager: A Practical Example
To showcase the capabilities of NovaLager, a “New Zealand style lager” or IPL (India Pale Lager) was brewed in the video. This involved a straightforward approach, emphasizing the yeast’s performance over complex techniques. The process detailed offers a clear roadmap for homebrewers looking to experiment with this exciting new strain.
The Grain Bill and Mash Schedule
A simple yet effective grain bill was chosen for the IPL. Joe White Signature Ale Malt formed the foundation, providing a robust base. This was complemented by 500 grams of Munich malt, which adds a pleasant malty depth and complexity, and 500 grams of oats, often used to contribute to mouthfeel and head retention.
The mash was conducted at 65 degrees Celsius (149°F) for 75 minutes, a standard temperature for good fermentability and body. A mash-out step followed, lasting ten minutes at 76 degrees Celsius (169°F), which helps to halt enzymatic activity and prepare the wort for sparging. Approximately 15.5 liters of water were then used for sparging, effectively rinsing the sugars from the grain bed.
Hop Additions for a Hoppy Lager
For an IPL, a significant hop presence is expected, and the chosen schedule reflected this. Bittering was achieved with 25 grams of Select Spalt hops added at 60 minutes into the boil. Later additions included 25 grams of Saaz hops at the one-minute mark, providing aromatic qualities, and another 25 grams of Saaz for a hop stand at 95 degrees Celsius (203°F) for 20 minutes. This technique helps to extract delicate hop aromatics and flavors without excessive bitterness.
A generous dry hopping was also performed post-fermentation with 50 grams of Saaz hops. This final addition contributes a fresh, intense hop aroma, crucial for the “New Zealand style lager” character. The original gravity aimed for was 1.050, with an actual reading of 1.053 being achieved, indicating a strong starting point for fermentation.
Fermentation and Conditioning: The NovaLager Difference
The wort was no-chilled, then a 20-gram sachet of NovaLager yeast was pitched the following day. Despite the relatively small amount of yeast for a 6-gallon batch (equivalent to about 22.7 liters), its vitality and efficiency were clearly demonstrated. The fermenter was set to an initial temperature of 15 degrees Celsius, later adjusted to 14 degrees Celsius to avoid shocking the yeast and to find a balance between speed and flavor development.
Pressure fermenting was utilized with a spunding valve set to 5 PSI. This technique is often used by homebrewers to reduce ester production, although the consensus from the video narrator is that pressures below 15 PSI do not significantly impact ester profiles. The rapid fermentation meant that dry hopping could occur after only four days, directly in the conical fermenter. After a few days of dry hopping, the beer was crash-chilled and kegged. The entire process, from pitching to kegging, was completed in less than a week, underscoring the revolutionary speed of NovaLager yeast.
Embracing the Future of Lager Brewing with NovaLager
The capabilities of NovaLager yeast present an exciting opportunity for homebrewers to simplify and accelerate their lager production. Its hybrid nature ensures a clean, crisp beer without the common pitfalls of sulfur or diacetyl, even at warmer fermentation temperatures. Imagine if, after just a few days, a perfectly conditioned lager could be enjoyed, boasting all the classic qualities without the usual waiting period.
This yeast truly signifies a shift in what is possible for homebrewers. It allows for experimentation with various lager styles, from traditional pilsners to experimental IPLs, all while benefiting from a dramatically reduced turnaround time. The enthusiasm surrounding NovaLager yeast is well-founded, as it addresses many of the challenges associated with crafting exceptional lagers at home.
