So what's the least amount of boil volume anyone has used, and how did it work out?
When using extract, it seems like the only practical reason to boil at all is to extract hop bitterness, and of course sanitize the wort. But more and more people, including myself, are having good if not better results by adding significant portions of the extract at the end of the boil. So what if you only boiled the amount of wort necessary to fully isomerize the hop alpha acids, and added the bulk of the extract at the very end? (And topped up to 5 gallons, or whatever.)
I have done boils as low as 2-3 gallons before, but I want to experiment with boils in the range of 1 gallon and below. And, these would not be concentrated boils. The boil gravity will be approximately the same as the OG, i.e. 1# DME/gal water. Of course, the remaining extract would have to be raised to an appropriate temperature for sanitation purposes. (Maybe not if it was in a sealed package...)
Anybody tried this? Am I missing something important?
