This barrel is made of American White Oak and was handcrafted to hold approximately five liters. It is held together by pressure with six black steel hoops and comes with a stand, bung and a spigot. The barrel has been given a medium char inside which caramelized the sugars in the oak. The charring of the oak is what allows the barrel to age your alcohol. These barrels are perfect for mellowing and enhancing the flavors of whiskey, bourbon, rum, tequila, scotch, brandy, cognac, red wines and vinegar.
