What Are FRESH™ Strains?

Fresh strains make cleaner tasting beer that judges and beer drinkers prefer. Until now, brewers have relied on imperfect methods for reducing total diacetyl, a distracting off-flavor that can impact quality at even very low levels. Our Fresh strains are engineered to produce the ALDC enzyme inside the cell, a reliable method that’s robust to process variation. Diacetyl rests are shortened, beer is packaged sooner, fewer forced tests are required, and above all, your customers will enjoy a beer that’s so fresh and so clean.

Fresh Data: Comparing Fresh Strains with Purified ALDC

Fresh Data: Comparing Fresh Strains with Purified ALDC

To test how different yeast and ALDC treatments would impact diacetyl levels, we designed a recipe that we knew would result in high diacetyl after dry hopping. The beer was formulated with 15% maltodextrin and dry-hopped with a varietal known for its high diastatic potential. The combination of maltodextrin and diastatic activity drives significant hop creep.
