I'm trying to complete a recipe that calls for Perle Hops. But the only kind that the store has right know are whole leaf Perle hops. I've never used whole leaf hops before so I just wanted to get some thoughts on using whole leaf hops.
I'm not really sure, but from what I've picked up, whole leaf hops are better for flavoring/finishing since the lupulin glands are still in-tact. But leaf hops will soak up more of your wort (decreasing volume), and can be a little messy. If I can, I use pellets for bittering, and leaf for flavor and aroma.
I wouldn't bother making any adjustments. The bittering add could be increased by 0.1 oz. if you are deeply concerned, but flavor & aroma are fine as-is.
