Nine years after selling its first kegs, Surly Brewing Co. will be releasing a new beer commemorating the anniversary.

The Brooklyn Center, Minn.-based brewing will be releasing NEIN, an ale that is brewed with oak-smoked malt that has been fermented with Germa Hefeweizen yeast before being aged on charred oak. According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), new beer was inspired by a recent trip to Bamberg, Germany.

“Who would have thought, when we sold our first keg in 2006, that we would raise our 9th Anniversary glasses in a new brewery, restaurant and beer hall?” reads the beer label. “So much has changed in such a short time, both at Surly and across Minnesota. The state’s beer scene is exploding and we are proud to have been part of the boom. Two things, however, haven’t changed at bit — Todd’s distinctive take on beer styles and our local artists’ amazing talent. Cheers to nine years!”

Although brewing started in late 2005, Surly sold and delivered its first beer, Furious IPA (6.2 percent ABV) in February 2006.

According to the brewery, NEIN will be packaged in 750ml bottles. An email to the brewery for additional details was not immediately returned.
