Potion

Potions are brewable items that confer specific effects in Minecraft. Potion effects were initially introduced in Beta 1.8. Potions are made using water and various ingredients combined in a Brewing Stand. As of Beta 1.9 Pre-release 3, potions can only have one effect. Because the data values for different potions were changed, Potions made in 1.9 Pre-release 2 will be altered if loaded into 1.9 Pre-release 3

There are 4 tiers of potion (e.g.: Speed I, Speed II, Speed III, Speed IV), but the present brewing system does not allow the production of level III or IV potions.

History
Alchemy was first hinted in July 2010, when Notch explained why redstone ore disintegrates into "dust". He states that dust will be used later in potions.

A couple months later, Notch did a Q&A session on Reddit. He was asked about Alchemy, and responded "Oh Yes! Definitely!". All of his posts in that thread are now deleted, but records can be found in other places.

Potion effects were introduced in Beta 1.8. Jeb later tweeted a screenshot showing potion durations and Glass Bottles taken from within Beta 1.9 Pre-release 2.

Originally Potions were to be brewed in Cauldrons. Jeb later tweeted that both he and Notch had come up with a different way to brew potions, which was revealed to be Brewing Stands.

In Beta 1.9 Pre-release 4, Splash potions were introduced. You can turn any potions into Splash Potions by brewing Gunpowder into a potion (even Instant Health II). It appears in a different shaped flask. Instead of drinking it, you throw it like a grenade.

Brewing
For ingredients that go into Potions, Splash Potions, and known Potion recipes see Brewing. According to Jeb there are 161 possible potion combinations in Beta 1.9 Pre-release 3, and there may be 2,653 potions in future updates.

Potions
Here is a full list of the names, effects, and damage values of potions that are currently obtainable through Brewing.

Potions have a different effect according to their damage value. By using a SMP command /give or an Inventory Editor to modify the damage value of a Water Bottle, a player can hack a potion directly into their inventory.

Base Potions
All base potions have no effect when drunk.

Primary Potions
Note, that the duration of tier II potion is always half the duration of its base potion, and the duration of extended tier I potion is 8/3 the duration of base.

Splash Potions
Note, that the base duration of splash potion is always 3/4 the duration of corresponding drinkable potion.

Unused Potions
There are 17 unused potions which all appear to be base potions. Here is a list of their names and data values:

Potion Effects
Potion effects are conferred by Potions, or alternatively through Splash Potions. As of 1.9 Pre-release 4, a player affected by a potion effect emits swirling particles the colour of the potion for the duration of the effect.

Trivia

 * Taking a potion while already under the effects of another potion does not add onto the effects time, but simply resets it. A potion effect will not "downgrade" if a lower level is activated. For example, if a player has Resistance III, drinking a potion with Resistance II will not have any effect.
 * An Instant Damage III Potion is powerful enough to instantly kill its victim(s).
 * Upon death, all potion effects are lost.
 * Using a portal to enter the Nether, the Overworld, or the End will cause potion effects to disappear.
 * A player can drink two potions quickly by switching to another potion immediately after drinking one, making it so that the second drinking animation will not be shown.
 * When you drink a potion, the animation uses the Eating animation, showing the Player "chewing" into the bottle. However, unlike the Eating animation, no bits of bottle are thrown out when a potion is drunk.
 * As of Release Candidate 2, drinking a potion or milk makes a kind of slurping sound.
 * Despite the speed bonus, a potion of swiftness, at any level, will not increase jump distance while walking.
 * There may be more than one legitimate damage value for each potion, such as how there are two kinds of Mundane Potion.
 * Hacking the game to give yourself stacked Potions surprisingly works fine; like filling a stack of bottles with water, the empty bottle will attempt to place itself in your inventory, and failing that, will throw itself onto the ground.
 * Splash potions of poison can prove useful for obtaining record discs from creepers, as they can damage the creeper enough for a skeleton to kill it, but will never kill the creeper by itself.
