A barrel is a cylindrical wooden vessel, often for liquids, made of staves held together with hoops; it’s also known as a “cask” or “tun”, or (in one 16th Century grant) a “kilderkin”. In some Society examples it may be blazoned a “keg”, particularly if it has a spigot inserted. The barrel is a period charge, found in the arms of the Worshipful Company of Vintners, 1447 [Bromley & Child 253].
The barrel is fesswise by default; its “proper” tincture is brown. For related charges, see tub.
