Brewing

Brewing is the method by which many potions are made in Minecraft. It is a function that will first be made available in Beta 1.10.(Possible 1.9) Originally potions were to be brewed in Cauldrons but Jeb later tweeted that he and Notch had come up with a different brewing method.

According to code found in the Beta 1.9 Pre-release 2, Potions are brewed by adding water to a Cauldron, and then combining ingredients. Ingredients in the correct combination would confer beneficial potion effects with no downside, or additional negative status effects. In 1.9, there will be a Brewing Stand to brew potions in.

Complete recipe list
Currently there are many ingredient combinations which result in many different potion effects. The following potions were commented by Jeb to be the "'clean' potions that don't require a lot of work."
