This preview version adds an optional duration field to brewing recipes and previews for recipe alternatives.

For a few more details regarding the split and future you can look at the roadmap to 1.21!

Changes

Assets

• Added four textures for the Brewing Stand recipe book alternatives overlay.

Items

• Renamed the #minecraft:mundane_potion_additions item tag to #minecraft:mundane_potion_reagents.

Recipes

• Renamed the addition field to reagent for brewing recipes.

So if you had this:

{
  "type": "minecraft:brewing_modify",
  "addition": "minecraft:sugar",
  "base": "minecraft:awkward",
  "result": "minecraft:swiftness"
}

You now have to use this instead:

{
  "type": "minecraft:brewing_modify",
  "base": "minecraft:awkward",
  "reagent": "minecraft:sugar",
  "result": "minecraft:swiftness"
}

• Added an optional brewing_duration field to brewing recipes, which is a positive integer representing the number of ticks the recipe takes to complete.
  • Its default value is 400.

Example:

{
  "type": "minecraft:brewing_modify",
  "base": "minecraft:awkward",
  "reagent": "minecraft:sugar",
  "result": "minecraft:swiftness",
  "brewing_time": 200
}
