Before you use it

It is a mash enzyme — boiling kills it, so it does nothing in the kettle. A 10–20 minute rest near 45 °C is the usual window; adding it to a single-infusion mash still helps but less so. Do not confuse it with AMG: this thins wort, it does not dry the beer.

Description

Breaks the β-glucan gums in oats, rye, wheat and undermodified malt that otherwise turn the mash into porridge and the lauter into a stall. Standard insurance in oatmeal stout, rye IPA and any hazy that leans on flaked oats.
