I have 1.5 oz each of cascade, columbus and chinook left total 4.5 oz . i am going to bitter w/ warrior. 2 oz. Wanted to flame out with the listed hops. OG should be 1065-1070 . question is that overkill for the flame out ?addition. Thanks,
Some people say too much hops give a grassy taste. Adding 4.5 oz at flame out is probably under that limit though, and if the recipe calls for it then don't worry about it. You could split them up, do half at flame out, half dry hop.
I would put 1/2 ounce of each (1.5oz total) in at 10min, flameout and dry hop. Two ounces of warrior seems high for the OG.
