Wine barrels, especially those made of oak, have long been used as containers in which wine is aged. Aging in oak typically imparts desirable vanilla, butter and spice flavors to wine. The size of the barrel plays a large role in determining the effects of oak on the wine by dictating the ratio of surface area to volume of wine with smaller containers having a larger impact. The most common barrels are the Bordeaux barriques style which hold 59 gallons (225 liters) followed by the Burgundy style barrel which hold 60 gallons (228 liters). Some New World wine makers use the large hogshead 79 gallon (300 liter) size.
