Volume 19: Mosaic Single Hopped Rye Ale. Brewer “Spike” has an affinity towards rye malt, so this comes a no surprise. Freshly harvested from Hop Breeding Company, LLC in Yakima Valley, the hops used in Side Project 19 “Mosaic” came freshly picked from the fields of Perrault Farms, to our brewery, and into your glass. Known as hop HBC 369 before official naming in 2011, Mosaic is the daughter of Simcoe (YCR 14) and a Nugget-derived male. To get the best of all worlds from this new Humulus lupus, we used 100% Mosaic throughout the brewing process to utilize all the flavor and aroma that this world-class hop has to offer.
