I’m also typically around 16oz. 5# per bbl = (5x16) x 6.5 / 31 = 16.77 oz.12-16oz DH?? Holy shiiiii....I shoot for 7 gal of wort into my fermenter, and if I do 8oz+ DH I have issues getting a full 5 gal into the keg!
If you’re making beer you’re happy with, with 8oz, god bless you.
For those using a conical, I find that keeping a close eye on that sight glass really helps. With a small amount of pressure the hops eventually start to compact and essentially squeeze out a good amount of liquid. Drop small amounts at a time. I’ve been able to significantly reduce waste by refining process.
