In states like California and Idaho, acacia oak barrels for fermenting and aging wine is becoming an increasing trend. In Europe, acacia wood barrels are commonly used for wines and now gaining traction with white wines among American winemakers. Acacia barrels for wine are appealing not because they add flavor to a wine but because they reduce it. The normal traditional oak barrels add flavors such as spicy French or American oak, yet acacia barrel wine has more texture than flavor providing a better channel of wine taste for consumers.
