Abstract: Traditional vinegar production is a lengthy process which implies high operational risks and jeopardizes the organoleptic characteristics of the final product. In an effort to solve these problems without changing the traditional model, we modified the wood type and thickness of vinegar barrels. We acetified in triplicate in barrels made of acacia, cherry, chestnut, and oak and in three wood thicknesses (15, 20, and 25 mm) in two different vinegar plants. The operating volume was set at 60 L. Reducing wood thickness improved neither maximum acetification velocity or the total length of the process, and in some cases even worsened them. The process took longer in oak barrels than in other types of wood barrel in one of the vinegar plants. Therefore, the choice of wood is a parameter to be considered in the wine vinegar production.
