Guess I'm a little confused about IBUs. I always thought international bittering units was a measurement of bitterness- something that is quantifiable. So how can a beer with higher IBUs have less bitterness but more flavor? I agree with Denny that beer should is best enjoyed tasted and not measured, but when working with FW hopping and dry hopping (especially using a new hop) it is hard to know how much and how long. Is there a way of measuring how much flavor/aroma a hop will impart based on Alpha acid or some other metric?
