An ‘oak vat’ is a vessel made of oak used in winemaking to ferment must. Unlike fermentation vats made of other materials, such as stainless steel, oak provides the wine with characteristics such as aromas, flavours and textures derived from the wood during fermentation.

Once the alcoholic fermentation is finished, malolactic fermentation can be carried out and the vat can be used to age the wine or it can be used to make a ‘coupage’ of wines aged in different barrels.

Our vats, like the foudres and following the philosophy of Toneleria Murua, are manufactured using the immersion system which guarantees a total absence of possible greenness and provides more volume in the mouth during fermentation.
