Traditional wooden barrels in Cutchogue Modern aluminium beer barrels - also called casks - outside the Castle Rock microbrewery in Nottingham, England For other uses, see Barrel (disambiguation). A barrel or cask is a hollow cylindrical container, traditionally made of wood staves and bound with iron hoops. Someone who makes such barrels is known as a cooper. Contemporary barrels are also made in aluminium (also called kegs) and plastic. Barrels often have a convex shape, bulging at the middle. This constant bulge makes it relatively easy to roll a well built wooden barrel on its side, changing directions with little friction. It also helps to distribute stress evenly in the material by making the container more spherical. Casks used for ale or beer are equipped with shives, spiles and keystones in their openings.

The Romans began to use barrels in the 3rd century AD, as a result of their commercial and military contacts with the Gauls, who had been making barrels for several centuries. For nearly 2,000 years barrels were the most convenient form of shipping or storage container, for those who could afford the superior price. All kinds of bulk goods, from nails to gold coins, were stored in them. Bags and most crates were cheaper, but they were not as sturdy and they were more difficult to manhandle, for the same weight. Barrels slowly lost their importance in the 20th century, with the introduction of pallet based logistics and Containerization. In the late 20th century, large steel casks began to be used in the United States for the storage of nuclear waste. This system, known as dry cask storage, has proven to be very controversial, but it is seen as the most practical of few available alternatives until a site such as the Yucca Mountain storage facility opens. Aging in barrels Wine barrels in Napa Valley, California. Main article: Aging barrel The term "Barrel" typically referes to wooden vessels that are small enough to be moved by hand. This would include up to Puncheon size (see below.) Barrels are used for the storage of liquids, to ferment wine, and to age wine (notably brandy, sherry, and port) and whiskey. Some wine is said to be fermented "in barrel," as opposed to a neutral container such as a steel or concrete tank. Wine can also be fermented in large wooden tanks, often called "open-tops", because they are open to the atmosphere. Other wooden cooperadge for storing wine or spirits is called "casks", and they are large (up to thousands of gallons) with either elliptical or round heads. Beer "Barrels" Although it is common to refer to draught beer containers of any size as barrels, this is strictly correct only if the container actually holds 36 gallons. The terms "keg" and "cask" refer to containers of any size, the distinction being that kegs are used for pasteurised beers intended to be served using external gas cylinders. Real ale and similar beers undergo part of their fermentation process in their containers, which are called casks. Casks are available in several sizes, and it is also usual to refer to "a firkin" or "a kil" (kilderkin) instead of a cask.

The tierce later became the petrol barrel. The tun originally was 256 gallons, which explains where the quarter, being 8 bushels or 64 (wine) gallons, comes from.

This measurement originated in the early Pennsylvania oil fields, and permitted both British and American merchants to refer to the same unit, which was based on the old English wine measure, the tierce. Earlier, another size of whiskey barrel was once the most common size; this was the 40 US-gallon (151.40 liters) barrel, which was of the same volume as 5 US bushels. However, by 1866 the oil barrel was standardized at 42 US-gallons. Oil has not been shipped in barrels for a very long time [3] since the introduction of oil tanker ships, but the 42-US-gallon size is still used as a unit for measurement, pricing, and in tax and regulatory codes, each 42(US)-gallon barrel making about 19½ gallons of gasoline. Disciplinary use As the expression over a barrel (i.e. vulnerably at someone's mercy) recalls, a commonly available timber barrel has been used a cheap and convenient alternative (in fact a passive pervertible) to more elaborate whipping posts and other, often more 'ritual', appararus for corporal punishment, in the private sphere or even for judicial administration of lashes to the backside (usually the posterior: for the back a straiter position as over a bench is preferred) of bend-over culprits, as the following links show still in the British 1899-1902 Boers-repression (South Africa and prisoner exile on the Bermudas, whipping naked boys as artist-illustrated) and even 1937 Ohio village marshall strapping juveniles. compare the barrel pillory or Spanish mantle Sources and External links CorPun website on various corporal punishments Crates and barrels in videogames Wikimedia Commons has media related to: ]] de:Fass Search Term: "Barrel_%28storage%29" Categories: Containers | Wine
