Brewing

Brewing (or Alchemy) is the process of creating potions, splash potions and lingering potions by adding various ingredients to water bottles in a brewing stand.

Brewing potions
By placing one or more bottles in the lower three slots of the brewing interface, an ingredient in the upper slot, and blaze powder in the fuel slot, you can distill the ingredient into each bottle and brew potions which may be consumed to grant an effect to the player.

Every potion starts with a water bottle, made by filling a glass bottle at a water source or filled cauldron. Using blaze powder, the next step is to add a primary ingredient to create a base potion, which is usually Nether Wart, which creates an awkward potion and has no effects. By brewing a second ingredient into a base potion in the same manner, you can create a potion with a working effect. A third ingredient may be added to make the effect more intense or last longer, or turn the effect harmful. Gunpowder can be added to a potion at any stage to convert it to a splash potion, which can be thrown (or fired using a dispenser) to disperse its effect in a radius. Finally, dragon's breath can be added to a splash potion to convert it to a lingering potion, which can be used to disperse its effect in a bubble. Each brewing step takes 20 seconds.

Each blaze powder used as fuel provides 20 fuel points. It costs 1 fuel point to start brewing; this fuel point is not recovered if the brewing is halted due to removing the ingredient or the potions being brewed into.

Base Ingredients
Base ingredients are the starting point of all potions. Nether Wart is the primary ingredient added to water bottles at this stage, as it is required to make most of the potions. All other base ingredients will only allow the creation of variations of "Potion of Weakness".

Secondary Ingredients
Secondary ingredients imbue an Awkward Potion with a particular effect but do not alter potion duration or intensity. When added directly to a water bottle, any of these ingredients will produce a Mundane Potion (with the exception of fermented spider eye, which results in a potion of weakness and the golden carrot, which can't be brewed into a water bottle to make a potion).

Modifiers
Modifiers change the potion's properties. The "longer duration" and "more potent" versions of a potion can be forever interchanged.

Corrupting Effect: Fermented Spider Eyes will change a potion's base effect, often reversing it or producing a negative potion.
 * A "corrupted" potion usually does the opposite of the original potion.
 * Potions of Invisibility are considered a "corrupted" version of the Potions of Night Vision.
 * Instead of seeing at maximum brightness, you turn invisible.

Primary
All primary potions are created by brewing a single ingredient with a water bottle. All potions can be combined with gunpowder to create splash potions.

Secondary
Secondary potions are created by brewing an ingredient with a primary potion and can be combined with gunpowder to create their throwable splash potion counterparts.

Tertiary
Tertiary potions are created by brewing an ingredient with a secondary potion or another tertiary potion and can be combined with gunpowder to create their throwable splash potion counterparts.

Trivia

 * As long as at least one of the three bottom spaces is filled, the brewing will continue, and additional bottles of water or potion can be added. However, if the ingredient is removed, or the bottom 3 slots are emptied at any time during the process, the process will stop and nothing will have been brewed.
 * The three potions do not necessarily have to be the same.
 * Upgrading effect of potion that has no time parameter (i.e. Instant Health, Harming) with glowstone dust has no downsides.
 * Upgrading one of the above's level II effect using glowstone will seemingly revert it to the original (metadata-wise, this is not the case).
 * Upgrading a potion that has no level II effect (i.e. Fire Resistance, Slowness, Weakness) with redstone has no downsides.
 * Upgrading one of the above's extended potion using redstone will seemingly revert it to the original (metadata-wise, this is not the case).
 * Although Jeb said that in the 1.9 pre-release 3 there were 161 possible different potion combinations with 2,653 in the future, in the actual third pre-release only 22 different potions could be made without the use of external programs. Of those, 19 potions had one of 8 different effects.
 * The Mundane Potion made from redstone has a different metadata (64) than the mundane potion made from any other ingredient (8192). Unlike Mundane 64, Mundane 8192 can be made into a Splash Mundane Potion by adding gunpowder that is, like its base potion, without any effect.
 * There are many Potions that were left behind from 1.9 pre-releases that fill up different metadatas that otherwise cannot be brewed or obtained without a SMP server command or inventory editor. These potions include but are not limited to: Bungling Potion, Buttering Potion, Debonair Potion, Refined Potion.
 * More water can be taken to the Nether in one trip by filling water buckets, carrying a stack of glass bottles, and using a cauldron. This is because stackable glass bottles do not stack once they have been filled with water.
 * Undead mobs (zombies, skeletons, zombie pigmen, and Withers) are unaffected by splash potions of poison and regeneration, take damage from instant health splash potions, and gain health from instant damage.
 * Mixing Fermented Spider Eye with any base potion (including the ones that were left behind) will either result in a Potion of Weakness, a Potion of Invisibility, or a Potion of Slowness. The Potions of Slowness and Invisibility can only be brewed from the base potions that were left behind.
 * By modifying the item NBT using an editor or commands, it is possible to get a potion that cannot be upgraded into a splash potion.
