This is a "shell" recipe I use as a reminder/copied template for the typical stepped mash profiles used with the Speidel Braumeister and the effect on final product. Also useful for Grainfathers or any other programmable stepped mash system.

44 (30-52) 0-20 min.
Beta Gluconase - DO NOT SKIP for wheat beers or if many (20%) adjuncts (oats, rye, raw barley, wheat). Beta glucan can otherwise turn wort to jelly. Also, necessary if classic European malts with only moderate modification. If actually trying to use this step to lower pH >>>30 minutes.
-Deactivated at 50C
52 (50-55) 20 min.
Protease - Breaks up large proteins, decreased haze. Smaller proteins good for head and body. Many modern malts have this step completed during the malting, do not skip with very traditional old style malts. However, can also result in the loss of characteristics from modern malts where a specific protein profile is created by the malter for head retention, mouthfeel, etc ...
Peptidase - Produces free amino nitrogen, FAN can help fermentation, too much can produce off flavors. Often deactivated with kilning.
-Deactivated at 66C/72C
58 (55-60) rare step
Limit Dextrinase - For dry dry lagers, this enzyme is one reason for classic two step mashed Lagers. Will breakdown sugars not manageable by Beta and Alpha. Will remove much of the body from Dextrin malts.
-Deactivated at 60C
63 (60-65) 20-40 min.
Beta Amylase - Produces maltose. Long here means highly fermentable sugars, therefore dryer beer. Some malts with dextrin can add body even when long maltose stage is used: Carapils, DextraPils.
Low 60-61C, and long 40 min all fermentable wort resulting in dryer beer.
Higher 65C, and shorter 20 min for full body beers where many non-fermentable sugars remain in the wort.
-Deactivated at 72C
72 (68-72) 35 min.
Alpha Amylase - Produces a variety of sugars, including maltose and some unfermentable sugars.
Low for light all fermentable - 69.
Higher for full body unfermentable - 72 (increasing deactivation of Beta)
-Deactivated at 79C
Mash out 78C no more than 10 min, if sparge, no higher than 78C or risk bitterness from tannin extraction.
SINGLE TEMP WINDOW for my "SMaSTaSH" trials : 64-70
Single Malt @ Single Temp & Single Hop
Copy paste from web in Fahrenheit for non SI folks:
- 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.
