New Foeders & Casks

Keystone Fermentation Supply is proud to partner with the Romualdi Cooperage in Forli, Italy for all our large format wood vessels. A 4th generation cooper, Master Cooper Enrico Romualdi crafts each new foeder or cask by hand in the traditional coopering method of Italy. Wood for each vessel is carefully selected from a wood mill that his family has been using for generations. After sorting, the wood is then aged outdoors for a minimum of 60 months, where is it lovingly tended during it's aging process. Each stave for your vessel is milled a minimum of 55mm thick, with head staves on casks being milled even thicker, with a minimum of 65mm. Thicker staves are essential for the structural integrity and longevity of your vessel, which is why Romualdi vessels are well known among vineyards all across Italy. Following generations' of teaching, Master Cooper Romualdi then builds each foeder or cask to suit, including all stainless steel accessories and custom wood stillage. With proper care and use, your new vessel will last for a lifetime's worth of drinking!
