So-called “butts” are 600-liter (160-gallon) American oak barrels used in the Jerez (Sherry) region of Spain for aging Sherry. Butts are nearly three times larger than a Bordeaux barrel, and are usually painted jet-black. Because the butts are arranged in rows four or five barrels high, and because a typical Sherry bodega has many thousands of such barrels, the visual impression is often startling. Butts are also known as botas in Jerez.
