Minecraft Vanilla Cauldron Brewing

A datapack that let's you brew potions using filled cauldrons.


To brew a potion, just throw the ingredients you would normally put in a brewing stand in a filled cauldron. Always add the blaze powder last, or it will brew a potion with whatever ingredients are in the pot. For example, to brew a Strong Splash Potion of Health, add nether wart, glistering melon, glowstone, gunpowder, and finally blaze powder.

To get the actual potion bottles, just right click on the cauldron with an empty glass bottle.

You can only fill up bottles in survival (or adventure) mode. Bottle filling won't work in creative unfortunately.

The Trade-off

The benefit of using a cauldron instead of a brewing stand is that it is much faster (and cooler). However, the trade-off is that you have to use a blaze powder per 3 potions brewed instead of the couple dozen[?] you get when using a brewing stand. But honestly, if you have a blaze farm it really doesn't matter.

It's Foolproof!

  • You can't brew a potion if there's already a potion brew in the cauldron.
  • Adding water to to a partially empty cauldron with a potion in it will dilute and destroy the contained potion.
  • You can leave a potion in a cauldron for as long as you want.
  • You only get 3 bottles per brew
  • Everything should work fine in multiplayer

Changed Recipes

  • Strength potions require a blaze rod instead of blaze powder (Example: Extended Lingering Strength ingredients: nether wart, blaze rod, redstone, gunpowder, dragon's breath, blaze powder)
  • Poison potions require rotten flesh as their main ingredient (Example: Splash Potion of Poison II: nether wart, rotten flesh, glowstone dust, gundpowder, blaze powder). NEW
  • Potions of weakness require a blaze rod and fermented spider eye (corruption of strength potion).

Custom Recipes

  • Potion of Luck uses gold ingots as its main ingredient. Not sure what this potion actually does, but you can brew it.
  • Bottle o' Experience requires emeralds as its main ingredient. Yes I added a recipe for this even though its the most useless item in game.
  • Potion of Mining requires an iron ingot as its main ingredient. This is a custom potion similar to the new Turtle Master potion. It gives you Haste and Slowness
  • Potion of Levitation uses Shulker Shell as its main ingredient. NEW
  • More custom potions will be added.


  • Download the mod above.

  • Extract the .zip file (just right click > extract, at least on Windows)

  • Open the new extracted folder and copy the "cauldronbrewing" folder

  • Go to the save folder of whatever save you want to install the mod on, and paste the "cauldronbrewing" folder in the "datapacks" folder. (minecraft > [save] > datapacks).

  • Run the /reload command in game on the world you installed it on, or just reload the world.

Feel free to make any suggestions.

Is not working for my server. Each time the datapack loads on server startup I get multiple errors, and nothing happens when I throw potion ingredients into a full cauldron (yes, adding blaze powder last). Any ideas?

The errors:
- Couldn't load function at cauldronbrewing:functions/setup.mcfunction
- Couldn't read function tag list minecraft:load from minecraft:tags/functions/load.json in data pack cauldronbrewing
Would it be possible to add functionality like in Bedrock where you can use arrows on the cauldron to make tipped arrows?

Thank you for this, by the way!

I also like the idea behind your pack! I especially like it when packs make new systems for other people to use. Such as your custom potions pack could definitely be a base for other people to make their own potions! :)

Just added installation instructions. I would also recommend redownloading it as I've updated it.
