I'm interested in using the parti-gyle system for collecting second runnings for a second beer. It's really intriguing because you can get two different (though similar) kinds of beer from one brew day without a lot of extra work. I've formulated two recipes (one for the first runnings and one for the second). I estimated 60 percent efficiency for the first and 30 percent efficiency for the second. Here are my recipes for a red and a stout:

Color:
26 HCU (~14 SRM)
Bitterness: 35 IBU
OG: 1.061 FG: 1.012
Alcohol: 6.3% v/v (4.9% w/w)
Grain: 6 lb. American 2-row
.5 lb. Dextrine malt (Cara-Pils)
3 oz. American crystal 90L
3 oz. American victory
1 oz. Roasted barley
Mash: 60% efficiency
