Hey everyone, I am doing Charlie Pap's 1554 (1447) recipe from Micro-brewed Adventures, partial-mash, and I am concerned about some things. This is my current mash recipe:
3lb. Munich Malt
1lb. Wheat Malt
1lb. Oat Malt
1lb. Caramel 120
.5lb. Caramunich 120
According to my calcs. this would give me a Diastatic power of 43, which I know is low, but it should still be able to convert right? Also, I am planning on doing the step mash suggested in the book which is a protein rest @ 132ºF for 30min. and raising to 155ºF for 30min. My concern is that the beta-amalayse won't really do anything at 132ºF and it will be denatured too fast at 155ºF that with such a low DP there won't be enough for proper conversion. What do you all think? I can always sub some Munich for 6-row, but if I don't have to I'd rather not (since the munich extract is already 50%-ish base malt). Thanks so much for your help; this question is making me a bit crazy.
