I'm planning my first parti-gyle next month. It will be a doppelbock/alt. I've run the calculations through and they work out on paper, but this is one of those things that I have been working on so long that I can't quite see the forest for the trees any more. I want to make sure that my math is solid.
The base recipe is follows:
18 lb Munich 10
2 lb Pilsner
1/2 lb Melanoidin
1/4 lb Carafa III
I plan on making 5.25 gallons of Doppelbock and 3.25 gallons of alt. Assuming 70% efficiency, that gives me 523 gravity points to work with. I will extract approximately six gallons of wort each with both the first and second runnings. I plan on taking two gallons from the second runnings and adding them to the doppelbock; then I will do a very long boil to get down to the proper final volume. The alt will get a regular 60 minute boil.
I'm getting a OG of 1.068 for the doppelbock and 1.051 for the alt. But just looking at that, the math does not seem right. Please someone confirm this for me!
