Barrel

Barrels are blocks found in various structures that allow you to fill an empty mug with the drink they contain. You can also craft  barrels and brew various drinks in them. They can be crafted on a normal crafting table using wood planks, iron ingots, and a bucket.

Crafting

Barrels can be placed in water by right  the water with the barrel in hand. The barrel can then be ridden, similar to a boat, but slightly slower. Barrels do not break when they hit a shore, but when broken with your hand or a tool drop a barrel.
