Seems I recall somebody talking about this technique... what is this called?
If so, how to to prevent tannins when you are sparging the hell out of the grain? For that matter, how are you making anything when the extraction has GOT to be pretty low efficiency?
Perhaps I was just confused with what somebody was saying.
Yes, there are several really good threads here about that very technique. The simple answers to some of your questions are...
You start with a considerably large grain bill. You stop the first runnings far above the limits of tannin extraction, and you produce two beers. The first will be a big beer, maybe 1.080+ and the second may only be 1.040ish.
I did this with the 999 Barleywine and also produced a very good ESB. If you want the recipes, I can send them to you. But technique is probably more critical than recipe other than the starting grain bill.
