I've come across an extract with steeped grains clone recipe for a Brown Ale I really like. It calls for 1lb of Crystal 60 malt for a portion of the steeped grains. My local Homebrew Shop stocks Crystal 40 and Crystal 80, but not Crystal 60. Would it change the flavor/character of the beer much if I used 8 oz. of Crystal 40 and 8 oz. of Crystal 80?
