I have never used this stuff and was wondering about it. First it seems there is no designated hop type. Another supplier listed it as Cascade but many if found from Googling it don't say. It's also a little unclear if it is best as a bittering hop addition or late. Can it be used like a dry hop? I guess it's like tar so boiling it and adding it with the water to a keg would seem to be about the only option.
Back when I first started brewing, almost twenty years ago, a friend that worked at a rather large brewery, might have had "weiser" in it's name, gave me a gallon jug of some kind of hop extract. He worked in maintenance so he really didn't know much about it. It sat on a shelf for a long time since I had not idea how to use it and I finally tossed it. Now I think I may have thrown out hundreds of dollars of stuff.
