Profile: Sonoma Cast Stone’s Concrete Beer Tanks

Stone Concrete Beer Tank Vessel Fermenter

Sonoma Cast Stone’s concrete beer tanks were one of the most buzzed about attractions at the recent 2015 Craft Brewers Conference, and The New School was there to capture video. Portland’s Hair of the Dog Brewing is the first brewery to purchase one of these concrete tanks, said to be perfect for fermenting and aging sour beer. The latest chapter in our occasional hi-def video series Behind the Pint profiles the California-based company that has been producing these space-age, egg shaped vessels for the wine industry for years.

Why would you want to use an extremely heavy concrete tank over standard stainless steel vessels? They are said to be extra porous, good for wild yeasts and bacteria to breathe and make a home in, they keep cool and even temperatures naturally well, and–what could be a plus or minus–impart a unique minerality to the beers flavor profile. Plus they are easy to clean and you can refresh the entire vessel between batches with an acid wash. Check the video for more info.
