Mikkeller started the trend (as far as I can tell) and now others are jumping on the bandwagon. There are citra hop IPA’s hitting the market from breweries like Kern River and now two other notable breweries are getting in on the action.
Bear Republic has the awesome Apex amongst other great IPA’s but the new one that caught my attention was…
ABV: 6.0% IBU: varies
Rebellion is a single hop pale ale brewed to showcase different hop varietals. Always brewed with the same malt base and IBUs, the character of the hop really shines through.
Then Terminal Gravity in tiny Enterprise, Oregon comes out with single hop DIPA’s! Using the “C” hops of Centennial, Chinook and Columbus.
Most of these are draft only so search for them.
