I've noticed that when ever I brew a beer with more than 8oz of hops, I get less beer in the keg. How do you adjust your water volumes in relation to hops?
As a stop gap, I've used Cryo hops (which are amazing) but I want to use the new varities that aren't avalible in cryo. I'll uasually do a nice bittering charge, then toss in a lot of late additions and whirlpool - between that and dry hopping I can easily use 10oz of hops and end up with way less beer than I want.
