I'll be doing a double decoction version of the Westy 12 clone on Sunday if anybody wants to cruise through. Gonna get started in the morning and be at it into the afternoon. Not sure how long it will take but definitely be at it for a while. Cheers!
My first double decoction I did last weekend added just about 4 hours to my already 4 hour brew day. Hopefully the hefeweizen turns out better then other times and if so the added 4 ish hours will be well worth it each time.
