How to Brew Potions in Minecraft 1.21+: Recipes and Automation. The Complete Potion Guide.

Brewing provides buffs for survival and PvP: from a speed boost to full immunity to lava. To start brewing, you'll have to head to the Nether — the key ingredients and fuel only generate there. The process boils down to four stages: filling bottles with water, brewing a neutral base, adding an active effect, and enhancing it with modifiers.

Preparation

To get started you need equipment, a water source, and basic ingredients. The Brewing Stand processes up to three bottles in a single 20-second cycle.

The fuel goes into the left slot of the stand. The yellow gauge shows the remaining charges.

Step 1. Brewing the Base

Most ingredients don't work with plain water. If you add an effect directly to a Water Bottle, you'll get a Mundane Potion with no properties at all. The exception is the Fermented Spider Eye, which with water yields a Potion of Weakness.

The only correct base for useful potions is the Awkward Potion.

• Place 3× Water Bottle in the bottom slots.

• Place 1× Nether Wart in the top slot.

• Wait 20 seconds.

Step 2. Adding the Active Effect

After creating the Awkward Potion, an active ingredient that determines the effect is placed in the top slot.

Positive Effects

Negative Effects

Negative potions are created by corrupting positive ones with a Fermented Spider Eye. It inverts the base effect.

Step 3. Enhancing with Modifiers

A finished potion can be altered with modifiers. Redstone Dust and Glowstone Dust are mutually exclusive — you can't simultaneously raise a potion's level and extend its duration.

• Glowstone Dust: Boosts the effect to Level II (for example, Swiftness II gives +40% speed instead of +20%), but halves the duration.

• Redstone Dust: Extends the duration (from 3 min to 8 min, or from 1.5 min to 4 min).

• Gunpowder: Turns a regular potion into a Splash Potion. It is thrown by right-clicking and applies the effect to all creatures within a 4-block radius of the point of impact. The farther the target is from the epicenter, the shorter or weaker the effect it receives.

• Dragon's Breath: Turns a splash potion into a Lingering Potion. After it breaks, it leaves a cloud with a 3-block radius on the ground for 30 seconds. Everyone who enters the cloud receives the corresponding effect.

Tipped Arrows

Tipped arrows are crafted from a Lingering Potion . On the crafting table, place 1× Lingering Potion in the center and surround it with 8× Arrow. The output is 8 arrows with the effect. The effect of such an arrow lasts 8 times shorter than that of the base potion (a Slowness arrow will last 11 seconds).

Technical Details

The brewing process is rigidly tied to game ticks. One processing stage lasts exactly 400 game ticks (20 seconds at a stable server TPS). If you remove the ingredient from the top slot during the process, the timer instantly resets to zero. If you take out one of the bottom bottles, brewing continues for the rest.

The Brewing Stand generates a block update at the start and end of operation. A Comparator reads the stand's state and outputs a signal from 0 to 3, depending on the number of bottles in the bottom slots.

Splash potions exist as physical entities (Entity) during flight. Their flight speed adds to the player's momentum. If you throw a potion while sprinting and jumping, it will travel 30–40% farther than when thrown from a standstill.

Advanced Options: Automation

The stand has a fixed slot distribution when working with a Hopper block:

• From the top: Loads ingredients into the top slot.

• From the side: Loads bottles into the bottom slots and fuel on the left.

• From the bottom: Extracts finished items.

For potions to finish brewing, the bottom hopper must be locked with a redstone signal. A simple timer circuit:

1. Place a Hopper under the stand, connected to a chest. It is disabled via a Lever.

2. Load Water Bottle into the right hopper.

3. Load fuel into the left hopper.

4. Load Nether Wart into the top hopper.

5. After brewing finishes (after 20 seconds), you flip the lever for 1 second. The potions drop down, and the side hopper instantly refills the stand with new bottles.

For large-scale production, cascade machines are used: 3–4 Brewing Stands stacked one below another. The first brews the Awkward Potion and passes it down. The second adds Sugar, the third — Redstone Dust. This way you pull ready-made Potions of Swiftness (8 min) straight from the bottom chest.

Common Mistakes and How to Avoid Them

• Mistake 1: Trying to add Redstone Dust to a potion that already has level two (after Glowstone Dust). The game mechanically does not allow a potion to be both powerful and long-lasting. The modifier simply won't start brewing.

• Mistake 2: Trying to automate filling bottles with water via hoppers from a cauldron. Bottles aren't filled with water like ordinary items. This is done either manually (right-click on water) or with a Dispenser block aimed at a water source.

• Mistake 3: Throwing a Splash Potion of Harming into a crowd of zombies or skeletons. The Potion of Harming heals the undead, so to deal damage to these mobs use a Splash Potion of Healing.

• Mistake 4: Ignoring the fuel slot. If you don't place Blaze Powder on the left, the stand will accept the ingredients and bottles, but the brewing process won't start.

• Mistake 5: Hitting the target directly with a splash potion. The potion breaks against the mob's hitbox, the explosion's epicenter shifts, and the target receives a reduced effect. Throw the potion right at the mob's feet or at a block above its head so the radius is guaranteed to cover the target.

Conclusion

The potion system is needed for exploring complex dimensions and bosses. The Potion of Fire Resistance reduces the risks in the Nether to zero, the Potion of Weakness is a tool for getting discounts from zombie villagers, and the Potion of Slow Falling saves you during a fight with the Ender Dragon, when it tosses the player high into the air. In PvP, Splash Potions of Harming II deal fixed damage that pierces even netherite armor with Protection IV.

The downside of the system is the inability to stack bottles in the inventory. You won't be able to cram your backpack with dozens of potions. For long expeditions you should pick only the most essential ones, or switch to tipped arrows: a stack of arrows with an effect takes up only one inventory slot.
