The version I've been brewing lately, adding 3oz orange peel and 1oz coriander at end of boil, has been a BIG hit, especially with my Bud Light drinking friends. The orange and coriander diminish the Cascades though, just an FYI.
ALSO - my last batch I added 2.5oz of Gran Marnier to the bottling bucket. Magnifique!!! Adds a such a subtle different flavor. A killer orange pale ale.
