Deepening our bond with Sierra Nevada Brewing Co., forged with the 2009 collaboration Life & Limb, we've brewed an East-meets-West Imperial IPA called Rhizing Bines. “We had a lot of fun brewing the original dark and roasty Life & Limb in Chico with the Grossmans and Sierra Nevada’s extended family,” says Dogfish Head President and Founder Sam Calagione. “We are very proud of the way that beer turned out. Now it’s our turn to repay that hospitality and brew a very hop-centric IPA in Milton with our pals from Chico, incorporating innovative ingredients and techniques from both breweries.” On the hot side, Rhizing Bines went through Dogfish’s signature continual-hopping process with floral and citrusy Bravo hops. On the cold side, it was dry-hopped with an experimental varietal so new it doesn’t yet have a name, just a number: Hop 644. A component of Sierra Nevada’s aroma-boosting Torpedo system made a pit-stop in Delaware for dry-hopping duty before it headed to Sierra’s new North Carolina brewery.
