No liquefaction and saccharification step converts 100% of starch into simple fermentable glucose. A portion always remains as un-fermentable sugar — carbohydrate fragments that yeast cannot use directly, no matter how well the fermentation stage itself is run. A fermentation booster enzyme is built to close exactly this gap, and it’s often the single highest-leverage […]
Once alpha amylase has liquefied starch into shorter dextrin chains, that mash still isn’t ready for yeast. Yeast can only ferment simple sugars, and dextrins, while shorter than intact starch, are still too complex to be fermented directly. That final conversion — dextrins to glucose — is glucoamylase’s job, and it’s arguably the stage where […]
