yafuce's Stacking Potion
by yafuce
yafuce's Stacking Potion raises the stack size of potions on Fabric, so potion items take less inventory room than in vanilla.
What it does
Vanilla potions stack to a single item, which makes carrying several of them costly in inventory space. This mod changes that limit: drinkable, splash and lingering potions can all be stacked higher, with the author's notes giving 8 for drinkable potions and 4 for splash and lingering ones. Long water breathing sessions, speed boosts for travel, Nether roof trips and many other uses become easier to plan when a few potions can be carried at once.
The mod is server-side only, so only the server needs it and players join without installing anything. It requires Fabric API and is released under the GNU General Public License v3.0 only, with source code and an issue tracker published. Its single file targets 1.21.11 for Fabric. Builds exist for the 1.21 – 1.21.11 range, and snapshot builds are not part of the Modrinth page.
Key features
Larger potion stacks
Drinkable, splash and lingering potions stack beyond their vanilla limit of one item.
Drinkable potion stacks of eight
Drinkable potions stack up to eight per slot, so a carried set takes fewer slots.
Splash and lingering stacks of four
Splash and lingering potions stack up to four per slot in the same inventory.
Light server-side change
The change runs on the server alone and adds only the stacking limit, with no new items or recipes.

Who it’s for: Server owners who want potions to take less inventory space, and players on those servers who prefer to carry a supply of potions on trips.

What the author says
The fact that potions are unstackable outweighs almost all of their benefits. As they stand, potions are just cluttering you precious inventory space.
