Full Sail just touches on the grapefruit, in my opinion. I just made an IPA with the largest grapefruit/citrus aroma, taste, and bittering I have ever done. For most, this would be too extreme. Grapefruit champagney in aroma - never achieved this before. Lots of hops, but centered on Nelson and Citra with large dry-hopping Amarillo and Nelson. Crazy fruity hops! And, the Rye malt addition seems to add to it all!
