The term "barrel" describes in the field of logistics the gathering together of goods or a complete cargo unit. Goods can be gathered for transport or storage into the most suitable units or linkages possible.
Brief description
The original concept of a barrel originated from a container for wine, which used to be, as it is nowadays, filled into bottles and barrels. Nowadays, when we speak of barrels (in the sense of wine production), we mean a tank or barrel filled with an indefinite amount of wine. The term is also used in the chemical and pharmaceutical industries.
