Barrels are sturdy containers used to store and transport liquids and other materials. Traditional wooden casks are made from shaped staves held together by hoops; their curved sides help the container withstand pressure and make it easier to roll. Modern industrial barrels, often called drums, are commonly made of metal or plastic and serve different storage needs. The subjects represented here span beverage and industrial uses, including beer and oil, alongside barrels distinguished by color, material, or placement on a stand.
