1.030 to a flat 1.000. Hope she tastes good.
It will. The enzyme might give it funny parched dry taste but that will drop out in a week or so.1.030 to a flat 1.000. Hope she tastes good.
Dry hopped mine yesterday. 1.032 to 0.997 in a week. Didn’t have exact ingredients but went with mix of Belgian pale, German pils and flaked corn. 50/30/20%. I caught an off flavor in the yeasty gravity sample but thinking yeast is still busy cleaning up and it will be fine.
Fugging nice looking beer!!!View attachment 632353
Came out great. This is about 6 days in the keg. I cold crashed and fined with gelatin before kegging. Burst carbed at 50psi for 18 hrs then dropped to serving pressure. That off flavor was in there on days 2-3 but faded by day 4 and you have to hunt for it now. Really happy with how this came out!
I don't know. I have only used amylase enzyme.@Schlenkerla , you spec "amylase enzyme" and @Brooothru used glucoamylase
I can buy either enzyme and I'm wondering if it matters.
They appear to be the alpha vs beta amylase (amylase vs glucoamylase) but I'm not entirely certain.

The gluco will make it even drier because it will break down all of the complex sugars instead of just the 4 chain. This is what I have read anyway. The brut IPA thread suggests using the gluco specifically because of this.@Schlenkerla , you spec "amylase enzyme" and @Brooothru used glucoamylase

I normally don't secondary--is that a requirement for this recipe, or can I just add the AE at the end of primary fermentation? I use SS Brewbuckets, and generally cold crash for 3-7 days after completing primary, then keg for carbonation.
I do have spare kegs if secondary-ing is necessary. If so, is there a risk with leaving it in secondary with the AE longer than 14 days? Thinking about brewing this about a week before going on a 2.5 week vacation, and transfer/carb when I get back.
I think either should work.Hm. "Alpha Amylase Formula", what I found and got after quick search, 1lb, is 96% dextrose.
Is this the right stuff or should I have gotten the little bottle?
FTR - I'm the OP.https://byo.com/article/understanding-enzymes-homebrew-science/
“Alpha amylase is the enzyme responsible for breaking large, complex, insoluble starch molecules into smaller,soluble molecules. It is stable in hot, watery mashes and will convert starch to soluble sugars in a temperature range from 145° to 158° F. It requires calcium as a co-factor.
Beta amylase is the other mash enzyme capable of degrading starch. Through its action, it is the enzyme largely responsible for creating large amounts of fermentable sugar. It breaks starch down systematically to produce maltose.
Beta amylase is active between 131° and 149° F. But like all enzymes, its activity reaches a peak, declines, and then drops precipitously as temperature increases. The rate is also dependent on the amount of enzyme present. It takes time for all of the enzyme to be destroyed, but what is still intact works very quickly. So as the mash temperature approaches 149° F, beta amylase is operating at its fastest rate but it is also being denatured.”
So what does anybody believe they are accomplishing by adding enzymes to a secondary fermenter at room temperature? Enzymes are naturally present in the malted barley (which is why we mash around 150-155, to get a compromise temperature where these 2 enzymes function) and if you add extra enzymes, they are supposed to be used in the mash as they work at higher temperatures. I don’t know that adding enzymes to a secondary fermenter at room temperature or below accomplishes anything
