SafBrew LD-20 Yeast

Brew exceptionally clean, crisp, and highly attenuated lagers with SafBrew LD-20 Yeast, an innovative lager yeast and enzyme blend developed by Fermentis for producing beers with reduced residual sugars and up to 20% fewer carbohydrates compared to the same yeast fermented without the included enzyme. Designed for brewers seeking a dry finish without sacrificing alcohol content or drinkability, this 25g packet is suitable for approximately 5-gallon batches and performs reliably across a traditional lager fermentation range.

SafBrew LD-20 combines a carefully selected lager yeast strain with a specialized enzyme system that increases fermentability by breaking down complex sugars into fermentable sugars during fermentation. This allows the yeast to achieve exceptionally high attenuation while maintaining the clean, neutral character expected from classic lager styles. The result is a highly drinkable beer with a crisp finish, minimal residual sweetness, and a balanced flavor profile that works well for light lagers, reduced-carbohydrate beers, and other recipes where dryness and refreshment are priorities.

The strain performs best between 53–68°F (12–20°C) and delivers a very high attenuation of 98–102% with high flocculation, helping produce bright, clean beer after fermentation. The integrated enzyme blend supports efficient sugar conversion throughout fermentation while preserving the smooth fermentation profile associated with quality lager yeast. This combination allows brewers to reduce carbohydrate content without compromising overall alcohol production or fermentation performance.

For best results, ferment within the recommended temperature range and follow the manufacturer's pitching and rehydration recommendations. Proper wort oxygenation and appropriate yeast nutrient additions are recommended to support healthy fermentation, particularly when targeting maximum attenuation. Standard lager fermentation practices, including adequate conditioning time, will help produce the cleanest flavor profile and optimal clarity.

Produced by Fermentis to professional brewing standards, SafBrew LD-20 is widely used by homebrewers and commercial breweries seeking dependable fermentation performance for dry, clean lager production. Its advanced yeast and enzyme formulation provides a reliable solution for brewing highly attenuated beers with reduced residual sugars while maintaining the crisp character expected from quality lager styles.
