Phytase (86-126 F) – Lowers the pH of the mash. Lowering the mash pH has a number of benefits, though a Phytase rest is rarely used by modern brewers.
Debranching (95-112 F) – Helps to increase the solubility of starches resulting in increased extraction for certain malts.
Beta Glucanese (95-113F) – Breaks down the gummy heavy starches, which can help improve stability and extraction, particularly for mashes high in proteins and adjuncts such as wheat.
Pepidase (113-131F) – Produces free amino nitrogen, which can aid in fermentation.
Beta Amylase (131-150F) – Produces maltose, the main sugar fermented in beer.
Alpha Amylase (154-162F) – Produces a variety of sugars, including maltose and also some unfermentable sugars. Mashing at the higher end of this range produces more unfermentables and therefore more body in the finished beer.
