Auto-brewer
1 brewing stand · 42 blocks
Brews the water bottles of its bottles chest into potions of swiftness in its brewing stand: it puts in one nether wart (awkward potions), then one sugar, burns blaze powder from its fuel chest and collects every finished potion in its output chest, 1.9 potions a minute per stand.
Set up for potions of swiftness (nether wart, then sugar); another second ingredient in the sugar chest (a magma cream, a golden carrot...) brews its potion the same way. Keep the chests in order: sugar on water bottles makes useless mundane potions.
its first potion within 1 min 24 s · fits in 3×6×5
Try it
Watch a wart, then a sugar, go into the top of each brewing stand while the bottles go into its side; the finished potions drop into the output chest (the numbers over each container show what it holds).
How this design does it: One brewing stand in a 3x6x5 box: a clock (two hoppers passing 106 stones back and forth, a copper bulb remembering the direction) splits time into two halves of 42 seconds.
Build it
Download .litematic Download the design as text
The .litematic opens in Litematica (Minecraft 26.3): every block of the design in one region. The text file is the same build written as plain text, block by block.
Comes loaded with 106 stone in its containers: the download includes them; building it by hand, put them in first.

Details: how it works, measurements and properties
In depth
brews the water bottles of its bottles chest into potions of swiftness, a nether wart first and a sugar after it, burns blaze powder from its fuel chest and collects every finished potion in its output chest
How to try it
The brewer runs in the view: water bottles start in the chest tagged BOTTLES, blaze powder in FUEL, nether wart in WART and sugar in SUGAR; the machine puts one wart, then one sugar, into each brewing stand for every three bottles, and every finished potion drops into the chest at OUT. The numbers over each container show what it holds; speed it up with the bar's speed dropdown (a brew takes 20 seconds). Drag to look around, pinch or scroll to zoom.
Measurements
| metric | value | what it means |
|---|---|---|
| potions/min per stand | 1.9 | |
| first potion | by 1 min 24 s | |
| blaze powder | 1 for 8 brews | |
| hoppers awake | 9 | hoppers left unlocked at rest: each one looks for items every game tick (lag on busy servers) |
| at rest | no | whether the build comes to rest once its work is done (no: it keeps running, like an elevator's clock) |
| a | clock runs on | |
| blocks per stand | 42.0 | |
| bill | 60 iron, 3 quartz, 19 redstone | what its blocks cost to craft: iron, quartz, redstone, slime |
Notes from its designer
One brewing stand in a 3x6x5 box: a clock (two hoppers passing 106 stones back and forth, a copper bulb remembering the direction) splits time into two halves of 42 seconds. When the brewing half starts, the clock's own torch flashes under the block next to the bulb, which fires two droppers beside it: one lifts a nether wart into the hoppers over the stand, the other a sugar that takes two more hoppers and so arrives later, then waits until the wart is used up: the stand brews awkward potions, then swiftness. The bottles hopper beside the stand is unlocked only in that half and the hopper under the stand only in the other, when it takes the three potions to the output chest (a repeater keeps the bottles hopper locked a moment longer when the halves change, so a fresh bottle is never taken out unbrewed). Blaze powder goes into the stand's side from the fuel chest.
