content: This tool was collected from the quality assurance lab at Anchor Brewing Company in San Francisco, California. In a 2023 oral history, Andrea DeVries, the brewery’s quality assurance manager, explained how her tools and techniques had evolved over time. She said, “The manual pipette bulbs, when I first started working here, we did everything by hand. We had the glass-blown pipettes. I still to this day, if I'm in doubt, I'll pull out a hand-blown pipette versus a pipetter any day because there's nothing like liquid going up to a line and making sure you have that measurement. The bulb in the box was literally just an old bulb that was used to push the volume in and out of the pipette.”

content: Anchor’s approach to maintaining its yeast strain for Anchor Steam Beer was unique. As DeVries explained in the same interview, “[O]pen fermentation is a fermentation process that doesn't cause a lot of stress on the yeast…We could keep producing it and producing it and producing it in generations. I can't even tell you how many generations we probably are at today, but that was so unique to understand that process and realize that most of the brewing industry today is under a condition where they have to buy yeast that's propagated, stored in stressed environments. They are unfortunately committed to purchasing yeast from a lab, because they can only get ten to twelve generations out of a yeast strain. The uniqueness of Steam Beer is we could go on forever as long as we weren't stressing the yeast out.”

content: In 1965, Fritz Maytag III purchased the historic but struggling Steam Beer Brewing Company (later, Anchor Brewing Company). With his entrepreneurial roots and zeal for science, Maytag revitalized the brewery. He perfected the brewery’s recipe for steam beer, an effervescent style that had originated in nineteenth-century San Francisco, and brewed European styles—porter, barleywine, pale ale—then unfamiliar to many Americans. As a self-taught brewer and savvy entrepreneur, Maytag inspired many who dreamed of opening their own small breweries. Historians consider Anchor Brewing Company to have been the first post-Prohibition American microbrewery. Microbreweries, brewpubs, and “craft” breweries proliferated throughout the nation in the 1970s, 1980s, and beyond. In August 2023, Sapporo USA liquidated Anchor Brewing Company.
