FixPotionInventory
by NloobNeon_TH
FixPotionInventory lets drinkable, splash and lingering potions stack up to 16 per inventory slot, instead of the single-potion slots vanilla Minecraft uses.
What it does
Vanilla Minecraft gives potions a stack size of one, so each bottle takes a full inventory slot. FixPotionInventory changes this mechanic so that drinkable, splash and lingering potions stack together, up to 16 in a single slot. The stack size is configurable, and the change also covers potions added by other mods, so a modded potion can stack the same way.
The mod is aimed at players whose inventories fill up with brewing results and at anyone who wants a tidier potion storage setup. It is installed on the client and the server, and the installation needs Forge or NeoForge, or Fabric, as the mod loader. Files are published for Forge only, for seven release versions across the 1.20 line, with 1.0.0 for 1.20.6 as the latest file. It is not open source, and it is released under All rights reserved.
Key features
Stackable potions
Drinkable, splash and lingering potions stack together in one inventory slot, up to 16 each.
Configurable stack size
The number of potions per slot can be changed in the configuration, so server owners can set their own limit.
Modded potion support
Potions added by other mods follow the same stacking rule as the vanilla ones.
Cleaner inventory
Brewing results take fewer slots, which leaves more room for tools, food and building blocks.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Long brewing sessions
A player who brews large batches of potions keeps them in a few slots instead of a row of single bottles.
Server inventories
Server owners who run modded potion sets can tune the stack size to match their gameplay.
Who it’s for: Players who carry many potions and server owners who want a configurable stack size for potions, including those added by other mods.
How it compares
Stacking Potions is a Forge mod for 1.18.2 – 1.19.2 that is not open source and is released under All rights reserved, and it is also client and server. Sensible Stacks is open source under the Mozilla Public License 2.0 for 1.20.1, and it is server-side only, so players join without installing it. FixPotionInventory is client and server, so it has to be installed on both sides.

What the author says
Tired of potions cluttering your inventory? This mod is the solution! By default, Minecraft potions do not stack, taking up valuable inventory slots. FixPotionInventory changes this mechanic, allowing all drinkable potions, splash potions, and lingering potions to stack up to 16.
