Oak and Wooden Fermenters
Features
Oak and wooden wine tanks have played a key role in winemaking for centuries. These fermenters use natural wood, most often oak, to create unique conditions for wine fermentation. Oak barrels and oak foudres allow small amounts of oxygen to pass through their tight grain. This process, called micro-oxygenation, helps soften tannins and stabilize the color of the wine. Oak barrels also add flavors such as vanilla, caramel, coconut, and baking spices. The type of oak—American, French, Hungarian, or Slovenian—changes the flavor and tannin profile of the wine. New oak barrels give stronger flavors, while neutral barrels focus more on texture and less on taste. Oak foudres, which are large wooden wine tanks, offer gentle oxygen exposure and subtle flavor changes.
- Oak’s porous nature allows micro-oxygenation, which aids wine maturation.
- Oak barrels impart flavors like vanilla, coconut, and spices.
- Tannins from oak influence wine texture and aging.
- Different oak types and origins create unique wine profiles.
- Oak foudres and wooden wine tanks provide gentle, controlled oxygen exposure.

Best Uses
Winemakers often choose oak barrels and wooden wine tanks for fermenting white wines like Chardonnay. These fermenters help develop texture and mouthfeel, especially when the wine remains on lees after fermentation. Oak’s insulating properties affect fermentation temperature, which can change the wine’s flavor and structure. Red wines such as Pinot Noir and Cabernet Sauvignon also benefit from fermentation in oak barrels or oak foudres. The wood surface helps with tannin development and mouthfeel. Barrel size and shape vary by region and wine style. Burgundy uses pièces for Pinot Noir and Chardonnay, while Bordeaux and American wineries use different barrel sizes to influence the wine’s character. Oak and wooden fermenters work best for wines that need complexity, texture, and a traditional touch.
Concrete Fermentation Vessels
Features
Concrete tanks have become popular in modern wineries for their unique impact on wine quality. These vessels provide a neutral environment that does not add flavors or aromas, allowing the grape’s true character to shine. The thermal mass of concrete tanks keeps fermentation temperatures stable, which helps yeast work steadily and prevents sudden temperature changes. Porous concrete walls allow gentle oxygen exchange, a process called micro-oxygenation. This softens tannins and improves the mouthfeel of the wine. Many concrete tanks come in egg, cube, or conical shapes. Egg-shaped concrete wine tanks create a natural circulation of the wine and lees, which adds body and complexity. Concrete tanks also last a long time and resist mold and bacteria, making them a clean choice for winemakers.
Note: Concrete wine tanks offer better thermal consistency than stainless steel or wood. The slow heating and cooling protect yeast health, especially during native fermentations.
