A Brewing Stand is a craft-able block in Minecraft used in the Brewing process to make potions.
Brewing Stands are entity Blocks that are used for Brewing Potions by the Player. They were added in Update 0.12.1. They are also a Container.
The Brewing Stand was introduced to replace the Cauldron, which was deemed "not user friendly" by the Mojang team. It can brew three potions at once with only one ingredient.
