How It Works

All yeasts produce a-acetolactate during fermentation, as a result of normal metabolism. Once excreted from the cell, a-acetolactate is naturally oxidized into diacetyl before being reabsorbed into the yeast cell. At times, this reabsorption can be stalled when fermentation is less active, fermentation temperatures are low, yeast is removed too soon, or other processes are employed, leaving residual diacetyl in finished beer

Brewzyme-D is an a-acetolactate decarboxylase (ALDC) enzyme. It acts by converting the precursor a-acetolactate (the precursor to diacetyl) into acetoin, an odorless and flavorless compound.

Brewzyme-D is an enzyme that causes the direct decarboxylation of alpha acetolactate to acetoin, thus avoiding the production of Diacetyl and reducing maturation time. Brewzyme-D produced from a submerged culture of Bacillus subtilis.
