and other musical genres. Camusi retired in 1998 and sold his share in the company to Grossman. In 2010, Sierra Nevada Brewing partnered with the Abbey of New Clairvaux, with the monastery beginning production of Trappist-style beers in 2011. The Abbey has not yet been sanctioned by the International Trappist Association, and therefore the monastery will not be brewing official Trappist beer. The brewery employed about 450 people in 2011. In January 2012, Sierra Nevada announced it would build a second brewing facility with an attached restaurant in Mills River, North Carolina. The LEED-Platinum-certified building opened in early 2014 on a forested tract adjacent to Asheville Regional Airport, re-using the cut-down trees as lumber both in the building and for the rainwater cisterns that flush the toilets. In 2013, the company opened the "Torpedo Room" in Berkeley, their first tasting room outside of Chico. In January 2017, Sierra Nevada issued a voluntary recall of certain 12-ounce bottles of different beers in 36 states due to a manufacturing defect that had possibly introduced chipped pieces of glass into the bottle. Influence Along with Anchor Brewing Company in San Francisco and the now-defunct New Albion Brewing Company in Sonoma, whose owners offered Grossman and Camusi early guidance in their venture, Sierra Nevada is considered one of the earliest and most influential breweries which spawned the craft beer movement of the 1980s-90s. Grossman has been dubbed a "pioneer" by fellow craft brewers in the United States. Whereas many of the newly spawned microbreweries of the 1980s went out of business, Sierra Nevada Brewing endured to become one of the largest independent brewers in the country, whose beers were noted for their "character and complexity". Grossman believed many microbrewers of the early 1980s had put out an inferior product due to lack of preparation for the financial and mechanical realities of commercial brewing, which were a "much different process" from homebrewing. For its 30th anniversary in 2010, the company released a series of collaborative beers with the assistance of those Grossman considered an early influence on his brewing: Charlie Papazian, Fred Eckhardt, Fritz Maytag (Anchor) and Jack McAuliffe (New Albion). In November 2010, Stansbury Publishing released Hops and Dreams: The Story of Sierra Nevada Brewing Co, written by California State University, Chico professor Rob Burton, who researched the company for three years. The company has claimed to be neutral on political issues, and reiterated
