The Keg is the dedicated brewing block in Yeast ‘n Feast. It processes mead recipes using a custom keg recipe type, separate from the standard crafting and smelting systems. Crafting a Keg is also the entry point for the mod’s brewing advancement chain and is the registered workstation block for the Tavern Keeper villager profession.

​
Crafting the Keg

The Keg is crafted at a standard crafting table. Its recipe is visible in JEI under the keg recipe category.
Crafting your first Keg unlocks the Keg Stand advancement — the starting point for all brewing-related advancements.

​
Using the Keg

Right-click the placed Keg to open its GUI. The interface has six slots and a progress bar showing the current brew.

A recipe can use one, two, or three ingredient slots — the exact combination depends on the specific mead being brewed. The yeast and tankard slots are always required for every recipe.
1

Place the Keg

Set the Keg down anywhere you have room. It behaves like most solid utility blocks — no special orientation required.
2

Open the GUI

Right-click the Keg to open the brewing interface.
3

Fill the ingredient slots

Place the required flavour ingredients in the three ingredient slots. Check JEI (press R over the target mead) to see the exact items needed.
4

Add Yeast and a Tankard

Place Yeast in the yeast slot and a Tankard in the tankard slot. Both are required for every recipe to begin.
5

Wait for the progress bar

The Keg brews automatically once valid ingredients are loaded. The progress arrow fills from left to right. Default brew time is 7200 ticks (6 minutes); individual recipes may specify a shorter or longer time.
6

Collect the mead

When brewing completes, the finished mead appears in the output slot. Pick it up — the Keg will begin the next batch automatically if ingredients remain.

​
Recipe type and JEI integration

Keg recipes use the custom recipe type with the ID keg. This is separate from vanilla crafting, smelting, and all other recipe types. JEI displays Keg recipes in its own category, showing all six slots together.
If you are creating a datapack or a mod that adds new Keg recipes, use "type": "yeastnfeast:keg" in your recipe JSON. Required fields are ingredients (array of up to 3), yeast_slot, tankard_slot, output, and brew_time (integer, in ticks).
Example recipe JSON structure for reference:
keg_recipe_example.json
{
  "type": "yeastnfeast:keg",
  "ingredients": [
    { "item": "minecraft:honeycomb" }
  ],
  "yeast_slot": { "item": "yeastnfeast:yeast" },
  "tankard_slot": { "item": "yeastnfeast:tankard" },
  "output": { "item": "yeastnfeast:honey_mead", "count": 1 },
  "brew_time": 7200
}

​
Tavern Keeper villager

The Keg is registered as the work block for the Tavern Keeper villager profession. Placing a Keg in a village structure allows an unemployed villager to claim it and become a Tavern Keeper. Tavern Keepers trade mead-related items and brewing ingredients.

​
Tips for efficient brewing

Ingredient slots accept stacked items. Load a larger stack into each slot before leaving — the Keg will draw from the stack automatically for consecutive batches without you needing to reload it each time.
Each brew consumes one Tankard from the tankard slot. Drinking the finished mead returns an empty Tankard to your inventory, so your supply replenishes over time — but you need at least one to start.
Open JEI and search for the mead you want to brew. Press R on the result item to see the exact ingredient combination and brew time. This avoids gathering the wrong items.
The Sweet Victory, Sour Power, and Floral Finesse advancements each require brewing all meads in their category. Pick one category, gather all its ingredients together, then clear it before moving on.
