After six years of partnering with Third Street Brewhouse in Minnesota for most of their bottling and production, local brewers ~21ST AMENDMENT~ have found a facility here in the Bay Area. They’re planning to open a 95,000-square-foot facility in a former Kellogg’s Cereal plant in San Leandro, which will greatly increase their capacity for bottling. They’re hoping to open the new location later this year, followed by a tasting room and retail space in 2015. The new location will also serve as the brand’s world headquarters.
