Using Amylase Enzyme Brewing. The diastatic brewing enzymes break down and convert starch the endosperm of the grain into fermentable sugars and unfermentable dextrins. Posted August 14 2012 Joe - adding some amylase enzyme to the unmalted grains will give you starch conversion just make sure to do a cereal mash for any grain that is not pre-gelatinized or flaked. I dont remember where it ended but it was low but thats what I was hoping for. When doing a cereal mash you boil the unmalted grains into a porridge to gelatinize them and free up the starches for conversion.
The addition of alpha amylase also assumes your yeast is still viable as the glucose and maltose released from its activity would still need to be fermented out otherwise your beer might actually seem sweeter from the conversion of less sweet dextrins to sweeter glucose and maltose. Brewing enzymes enable you to achieve more consistent mashing improve filtration and optimize the use of variable raw materials. Amylase enzyme brewing is a great way to step up your brewing game. Likely a bad thing. This beer is created by designing your favorite IPA and adding the Amyloglucosidase enzyme to it during the mash cycle. The enzymes will take the beer to between 85-90 attenuation.
One of the major advantages of using a heat stable α-amylase over malt is that the brewer can ensure that there is no risk of residual starch carried over from the cereal.
Brewing enzymes increase starch liquefaction and saccharification which in turn increase the production of fermentable sugars. The use of additional enzymes is common throughout the brewing industry and is greatly beneficial. Brewers usually add a malt-equivalent blend of α-amylase β-glucanase and protease at the mashing-in stage or they may choose to add enzymes. It is advisable to seek out enzymes that have beta amylase in them also -so it will work in all three situations that I have listed in this document. Ideally these should be a suitable balance of simple fermentable sugarsglucose maltose and maltotrioseand. 8 Zeilen Beta-amylase is the other mash enzyme capable of breaking down starches.
