Wander Brewing recently increased its Barrel Project capacity by 620 gallons, after it purchased and installed a brand-new, 20-barrel foeder. This new vessel adds to Wander’s growing arsenal of more than 80 barrels.
A foeder (pronounced FOOD-er, and also spelled foedre or foudre) is a large oak vat that is often used for beers that require long-term fermentations, especially mixed-fermentation beers (i.e., beers fermented with Brettanomyces and Saccharomyces yeast strains) and mixed-fermentation sour ales (i.e., beers fermented with Brettanomyces and/or Saccharomyces, plus lactic acid bacteria such as Lactobacillus and/or Pediococcus).
Wander’s all-American-made foeder was built by St. Louis-based Foeder Crafters of America and it is made of Missouri-grown White Oak. (Many winemakers also use foeders, though they are typically made of French oak.)
