I was listening to a Brew Strong episode the other night, and the guys were talking about decoction mashing.
I was under the impression that the decoction method used the liquid, but they were saying you boil the grain pulled from the mash.
Another impression I was under, was that we lauter to separate the mash from the grain to boil.
So if you're going to pull grain to boil a number of times for up to an hour or more each time, how is that different than leaving the spent grain in the boil kettle?
I'm not interested in doing decoctions, it's just something that occurred to me.
