How to count brewing ingredients
Choose the effect
Pick the potion you want and the calculator works backwards through the chain that makes it.
Read the ingredients
It counts the nether wart, the effect ingredient and anything a variant needs, per batch rather than per bottle.
Check the fuel
Blaze powder is counted on its own line, because one powder fuels twenty brewing operations regardless of what is in the stand.
Take the bottles
A stand holds three bottles at a time, so the glass count follows the number of batches and not the number of potions.
How It Works
Pick a potion and get its brewing chain, ingredient list and durations.

How to Use the Brewing Calculator
Select a potion from the dropdown to see the complete brewing chain from Water Bottle to finished product. The tool shows every step with the required ingredient, a visual chain diagram, and a list of all materials you need to gather before starting. Use the Copy Steps button to save the recipe as plain text. The four Trial Chambers potions, Wind Charging, Oozing, Weaving and Infestation, are in this dropdown too, each with its full chain; the potion brewing guide goes further into what those effects do.
What Each Variant Adds to the List
Every modifier is another pass through the stand: one more ingredient, one more 20 second cycle, one more line in the ingredient list above. Redstone Dust and Glowstone Dust exclude each other, because the second one thrown in replaces the first, so a batch pays for one of the two and never both. Gunpowder then makes the batch throwable and Dragon's Breath turns that throw into a lingering cloud. Counted from a Water Bottle, an amplified lingering potion is five steps and five ingredients. What those variants actually do once the bottle is drunk or thrown is set out in the guide to every potion and its variants.
Brewing Efficiency Tips
Always brew in batches of three. The brewing stand processes all three bottle slots simultaneously with a single ingredient. One piece of Blaze Powder fuels 20 brewing operations, so keep a reserve near your stand. Plan your ingredient runs around the Nether since most key ingredients (Nether Wart, Blaze Rods, Ghast Tears, Magma Cream) come from there.
Common Potion Loadouts
For general survival, carry Fire Resistance (extended) and Healing II. For PvP, the standard kit includes Strength II, Speed II, Healing II splash, and Regeneration. For End exploration, add Slow Falling (extended) to handle Shulker knockback and void drops. For Ocean Monuments, combine Water Breathing (extended) with Night Vision (extended) for full underwater capability. Every ingredient in those kits carries a namespaced ID, all of them in the block and item database, and a finished bottle can also be handed straight to a player with the command generator instead of brewed.
What the brewing stand costs you
| Slots | Three bottle slots, one ingredient slot, one fuel slot. The ingredient is consumed once no matter how many bottles are in. |
|---|---|
| Brew time | 20 seconds, or 400 ticks, per step. A three step potion is a minute of standing there. |
| Fuel | One blaze powder covers 20 brewing operations, so a stack of 64 is 1280 brews. |
| Always brew three | One ingredient serves all three slots at the same time. Brewing one bottle wastes two thirds of every ingredient. |
| The first step | Nether wart on a water bottle gives the awkward potion that nearly every useful recipe starts from. |
| Modifiers | Redstone extends, glowstone strengthens, gunpowder turns it into a splash, dragon's breath turns a splash into a lingering cloud. |
Redstone and glowstone overwrite each other. A potion is extended or amplified, never both, which is why the variant table lists them as separate rows and not as a combination.
The chains were laid next to PotionBrewing in the client files of 26.2 on 8 August 2026, the class that holds every mix a stand can make. 19 of the 23 brewable potions have a full chain here, and the 20 seconds a brew takes is the BREWING_TIME_SECONDS constant out of that same class.
Fuel and yield per batch, counted from the 19 recipes on this page
A brewing stand works on three bottles at once and burns one blaze powder every 20 operations. Counting the operations in each recipe here turns that rule into a shopping list.
operations = the steps after filling the bottles: 1 for Weakness, 2 for fifteen of the recipes, 3 for the three that corrupt an already brewed potion with a fermented spider eyepotions per blaze powder = floor(20 / operations) x 3The three expensive ones are the three brewed out of another potion: invisibility from night vision, harming from healing, slowness from swiftness. What costs the extra step is the potion underneath and not the fermented spider eye itself. Four of the nineteen recipes here use that eye, and Weakness is the fourth: there it goes straight onto a water bottle, which is why it is the shortest recipe on this page at 1 operation and 60 potions from one powder. Only when the eye lands on a potion that was already brewed does the yield of a powder fall from 30 potions to 18.
Frequently Asked Questions
Questions about brewing
Why does redstone do nothing to my potion?
Because the potion has no duration to extend. Healing and harming act instantly, so redstone has nothing to work on. Glowstone still works on them since strength is a separate property from duration.
Can I have an extended and amplified potion at once?
No. The second modifier replaces the first. Adding glowstone to an extended potion throws the extension away and leaves you with the amplified version at its short duration.
How much blaze powder should I bring?
One powder per 20 operations. A chain of three steps for three bottles is three operations, so a single blaze powder already covers six full batches, which is 18 potions of that recipe.
What does the fermented spider eye do?
It corrupts a potion into its opposite instead of building on it. That is how night vision becomes invisibility and healing becomes harming, and it is why some chains are longer than the ingredient list suggests.
