Also known as Widmer Brothers Rotator IPA Series - Shaddock IPA
Commercial description
People sometimes describe the aromas and flavors of hoppy IPAs as "grapefruit." Hell, why not use some then? Widmerís brewing team used a simple IPA recipe and added a generous amount of dried grapefruit peel to the end of the boil. The aroma is a melody of citrus, with a slight spice undertone, accentuated by the use of Citra hops. The flavor is that of nice hop forward IPA with the bitterness of grapefruit.
