A wooden stave and barrel for the maturing or storage of alcoholic or spirit drinks, in which the internal side of the stave is machined to have at least two first channels and at least two second channels crossing with the first channels, determining a pattern of geometric elements. The elements remain submerged in the liquid contained in the barrel, providing a greater contact surface, thereby producing a greater transfer of the substances of the wood itself to the liquid. In addition, the pattern formed by the crossing channels permits a continuous and obstruction-free path for the liquid when it is extracted through one of the staves with an opening for the entry and exit of the liquid inside the barrel, thereby preventing unnecessary losses and unwanted internal residue for future reuse of the barrel.
