I don’t know the exact answer but I seem to agree with you.
In my current batch I added the amylase to the secondary of the first 5 gallons and primary to the second 5 gallons. The first 5 gallons took about 2 weeks to get down from 1.010 to 1.004 (where I felt it tasted good and kegged it). The second 5 gallons I just added amylase to primary on Sunday so I haven’t taken a hydro reading yet.
I’ll take one tonight and report back.
On the third 5 gallons (hooray from small grain bills that I can make 15 gallon batches!) I used a Kolsch yeast and will not be adding the amylase to primary since I am planning on harvesting the yeast. Not sure if the amylase would affect harvesting but I don’t really want to take the chance.
