Barrel is crafted from six wooden planks of any type and two wooden slabs in a hollow rectangle on the crafting grid. The device offers twenty-seven inventory slots — identical to a regular chest — but with one critical advantage: the lid swings open along the top axis instead of out the front. This means a Barrel can sit flush against any wall or under any block and still be accessed, where a chest would refuse to open.

The difference matters in compact builds. Storage rooms can stack barrels into tight grids without the half-block clearance chests demand. Hidden floor stashes work because there is no opening animation interfering with above-block placement. The block also serves as the workstation of the fisherman villager profession; placing one in a village without an active fisherman recruits an unemployed villager into the role, opening trades for cooked fish, fishing rods, and emerald exchanges. Hoppers, droppers, and comparators interact identically to a regular chest.
