I just brewed up a Diamond Knot IPA inspired brew this Saturday. It used Marris Otter, Munich and Crystal 20 for the malt bill and Homegrown Galena for bittering and finished with 20minute, 5minute and flameout additions of Columbus. I originally planned to dry hop with 2 oz of Columbus but I got to thinking it may be a bit one dimensional/grapefruity. So I thought maybe I'd add a bit of interest by dry hopping with 1 oz of columbus and one once of something else. Perhaps Chinook for a little piney mojo? I've never actually tasted DK IPA and I've never dry hopped with Chinook so I'd love a little input from folks who know what they're doing. So..please give your .02 on what hops I should dry hop with. My favs in general are columbus (obviously), centennial, chinook, amarillo, cascade and simcoe. Thanks!!
