I got this recipe from a few different sources, the main one was a recipe from a brewclub that were shown by Bill Covaleski a brewer for Victory how to make Prima. For awhile there was a shot online of the ingredient sheet, that wasnt supposed to circulate, the link to the recipe is below. Also I used replacement hops for Sladek, I got those from other clone recipes and the Victory website. Some people recommended doing a decoction mash, but I read conflicting reports on Victory's use of this technique, mash scheule below

Technically the hops are supposed to be whole leaf, but good luck finding whole leaf saaz and hallertaur hops around Humbodlt. The original recipe called for Sladek hops but I cant source these. So the subtitution is more saaz and hallertauer
