Do some of you continue to sparge/extract after your initial boil volume is collected and with these secondary runnings make a second brew?
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.
