Brewing Stand

The Brewing Stand is a block used for Brewing 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
Brewing stand is used to make potions in a more simple way than the cauldron. The process starts with glass bottles, which go in the 3 lower slots. The ingredients, which in the first round can be Nether Wart (Awkward potion, the base for other potions), Redstone Dust, Glowstone Dust, or Fermented Spider Eye (Potion of Weakness), go in the upper slot.
