Brewing Stand

The Brewing Stand is a block used for Brewing potions and splash potions, replacing the cauldron after the Beta 1.9 pre-release. It was revealed on September 30, 2011, when Jeb posted these 2 tweets:

Usage
A brewing Stand is required to make potions. When right-clicked, the brewing stand interface shows. The Brewing Stand interface has 4 slots. The bottom 3 slots are for glass bottles. These bottles must be filled with water or a potion. The upper slot is used to brew an ingredient into the potions below. The items which can be used as ingredients on water bottles are: Nether Wart (Awkward potion, the base for other potions), Redstone Dust, Glowstone Dust, Glistering Melon, Magma Cream or Fermented Spider Eye (Potion of Weakness). Brewing Stands will only drop as an item if mined with a pickaxe.

Trivia

 * When the first brewing stand appeared, it had an additional 2D sub-stand for bottles,(see the first picture in the gallery) but now the stands for bottles have been designed in 3D.
 * When you punch a brewing stand, it becomes darker.
