My recipe calls for a 5 min .25 ounce hop addition. Since I'm dry-hopping (not in the recipe), can I just throw the extra .25 ounces into my 60 minute to up the IBUs?
Aroma hop additions end up having a fairly different character than dry hop in my experience. I'd dry hop and do the aroma hop, personally (not having any idea what your recipe is).
I've heard strong opinions both way (dry hopping negates 5 min and under additions or they don't). I agree with llarian though. I do under 5 min additions and dry hop.
