How to Make an Auto Brewer

An auto brewer wraps a brewing stand in hoppers so water bottles, ingredients and fuel feed in and finished potions pull out on their own.

blaze powder fuels it

hoppers feed the ingredients

Hoppers drop water bottles and ingredients into a brewing stand, it brews all three at once, and a hopper underneath pulls the finished potions out. Keep it fed and it never stops.

What you need

A brewing stand

Blaze powder for fuel

Hoppers to feed and pull

Your potion ingredients

Three hoppers, three jobs

A brewing stand reads hoppers by direction. The top hopper loads the ingredient and blaze powder, the side hopper loads the three water bottles, and the bottom hopper pulls each potion out, but only once its brew is finished. Keep all three supplied and the stand brews batch after batch with no clicking.

Quick answers

What is an auto brewer in Minecraft?

It is a brewing stand wrapped in hoppers so it brews potions without you standing there clicking. Water bottles, the ingredient and the fuel are all fed in automatically, and the finished potions are pulled out the bottom, so you get a steady supply.

How does automatic brewing work?

The brewing stand has directional hopper slots. A hopper into the top loads the ingredient and fuel, a hopper into the side loads the three water bottles, and a hopper underneath pulls the bottles back out. Keep all three supplied and it brews batch after batch.

How do you feed a brewing stand with hoppers?

Point one hopper down into the top for the ingredient and blaze powder, run another into the side for the bottles, and put a third under the stand to collect. Each direction fills a different set of slots, which is what makes the whole thing automatic.

How do you only collect finished potions?

A hopper under a brewing stand will not pull a bottle until its brew is complete, so it naturally waits. For tighter control, read the stand with a comparator and only open the output once the brew progress shows done.

What can you auto brew?

Any potion, as long as you feed the right ingredient. Healing, regeneration, strength and speed are easy bulk brews; add a second stage with glowstone, redstone or gunpowder if you want stronger, longer or splash versions on the line.

Does an auto brewer work on Bedrock?

Yes. Brewing stands take hopper input and output the same way on both editions, though Bedrock timing and some slot behaviour differ slightly, so a Java layout may need a small tweak on Bedrock.

How to make a brewing stand

Craft the stand and learn the basic brews before you automate them.

Three bottles, three ingredients, no clicking

Hoppers feed the three slots separately

A brewing stand takes ingredients from the top, fuel from the side and gives bottles back out the bottom, so an automatic brewer is three hopper paths that must not cross. Getting the side hopper to carry blaze powder and nothing else is most of the build.

Timing beats detection

The stand takes a fixed time per brew, so a repeater chain set to that length is more reliable than trying to detect when the potion is finished. Designs that watch the output hopper tend to pull bottles mid brew and waste the ingredient.

Stock the wart first

Every potion chain starts with an awkward potion, so the machine burns nether wart faster than any other ingredient. A soul sand farm plot in the Nether next to the brewer is what keeps an automatic setup running instead of stopping after a chest of wart runs dry.
