I will be doing a public brew session this Saturday. Our LHBS is also a micro-brewer (Listermann), and is hosting an outdoor summer beer festival. My club is always given space to brew and recruit at their festivals. As a return favor for these events the beer I make goes back to the brewery. They ferment it, which makes it legal, and it becomes a small batch special for their tap room. Kevin, the head brewer, wants me to do a Belgian-American IPA with Mosaic hops. I've tasted Mosaic in other people's beers, but I've never gotten my hands on any to use myself. I'm looking for recommendations on how much to use and when. (I have 4 ounces available.) The other hops available to me are Sterling and Amarillo, and it will be fermented with BSI Ardennes (Chouffe) yeast. I'll be brewing 12 gallons, and shooting for an OG in the range of 1.070. Your recommendations are greatly appreciated!
