If you're looking to brew a Brut IPA or low carb beer this 1oz package of Amylo 300 enzyme is what you need.  Amylo™ 300 can hydrolyse sequentially both exo alpha 1,4 and alpha 1,6 glycosidic linkages and can therefore be used to degrade starch polymers and maltose to glucose, for the production of high alcohol and low carbohydrate beers.  

Amylo™ 300 is recommended for use in mash conversion, or in the fermentation/maturation stages of brewing.

Mashing and Wort separation - direct addition to mash during Saccharification rest, addition to wort before kettle boiling 

Fermentation and Maturation – direct addition to cold wort enroute to fermenter, and addition to storage /matured beer before filtration. 

Use 1-2ml per 5 gallons of wort.
