What mash schedule did you use for your Oktoberfest? Will be doing another this fall and will be the first on the BM. How did your boil volume turn out?
I used Hfk2's Mash schedule and it turned out great.
Protein rest 15 min @52C
Beta amylase rest 35 min @ 63C
Alpha amylase rest 35 min @ 70C
Mash out 15 min @ 78C
I started with 23 liters, sparged with 1.75g, ended up with a close to 5 gallons.
