I am going to do an extract with specialty grains (in a mini mash) clone of Ruthless Rye. Most everything will be NB Rye extract, but I will add 8 oz. chocolate, and 4 oz. flaked barley. I need something to get conversion started. Is a half pound of two row pale enough to get some conversion? I am getting like 52L which I think should be enough. TIA.
