Variable Capacity Wine Fermenters

Wine Tanks NW variable capacity wine fermenters can be used for both oxidative and non-oxidative wine fermentation. A “variable capacity” wine fermenter is essentially an open-top wine fermenter fitted with a sliding lid that can slide up and down the tank to accommodate variable sized batches of wine or the lid can be removed so that the fermenter becomes an open-top fermenter.  During fermenting, the tank lid can be removed to give the winemaker access to the “cap” which is formed from the wine skins on the top of the tank as the wine ferments. The winemaker, using a paddle, can stir or gently punch the cap back down into the wine in the tank then replace the lid.
