I'd say I easily lost 1 gallon all together. Ya, lots of trub. Then again when you're dry hopping with over 8 oz of pellets... I decided when/if I make this again, I'll dry hop with leaf hops in a bag. I'm hoping to slowly raise the bag from the beer to let as much drain out (without a lot of splashing) as possible to reduce the loss. Great beer either way! Enjoy!
