Sorry if this has been done before but I can't seem to find my answers. I've been reading about people adding crystal grains and hops and stuff and steeping ect at certain times in their boil. Is this with the coopers kits and stuff. I've been brewing kits for few years now and am now adding hops and Lme but just using hops like a cup of tea. Do people boil up the kits as well. Plz explain if you can thanks
