i'm brewing a "plambic" on monday and struggling with hops.
picked up 2 oz of opened, frozen and two year old hallertau and 1 oz of sealed, 4 year old pearle, also frozen.
they're now sitting in my oven at 200F and will be there for two hours.
i want to use both and toss the pearle in (1.0 oz) at 60 min and the hallertau (2.0 oz) at 15 but want to make sure my BUs are no more than about 14 (i know, high, but that's what i want)
i'm derating the acids across the board at 2/3rds... am i way off track?
