Fermented Spider Eye Recipe Tutorial (2025)

Fermented spider eyes are a highly sought-after potion ingredient in Minecraft — both Bedrock Edition and Java Edition. These ingredients are hard to find naturally, requiring a special crafting process to acquire them en masse.

This guide will cover how to craft a fermented spider eye and how to use the item in potion recipes to brew rare potions. After reading this, you can surprise your friends with all sorts of cool potion effects, such as invisibility or instant damage.

What Is Brewing In Minecraft?

Brewing is the process of creating potions with various ingredients. You need a Brewing Stand to make potions, as well as the potion’s specific ingredients.

What Is The Fermented Spider Eye in Minecraft?

The fermented spider eye is a brewing ingredient used to brew potions. What’s fun about the fermented spider eye is it generates the opposite effect of an already existing potion. For example, you can use a Potion of Healing to create a Potion of Harming, which afflicts its target with instant damage.

Are Fermented Spider Eyes Hard To Find?

In survival mode, you can only find fermented spider eyes in randomly generated chests within structures like a Desert Pyramid, a Jungle Temple, or a Woodland Mansion.

Of course, you can spawn as many fermented spider eyes as you’d like in Creative Mode.

What Is The Fermented Spider Eye Recipe?

The fermented spider eye recipe is simple, requiring a brown mushroom, sugar, and a spider eye.

However, acquiring these ingredients takes a bit of effort.

How to acquire a brown mushroom

There are a few ways to acquire brown mushrooms in Minecraft. The first is finding it in an area with low lighting — typically a cave.

While exploring the game’s generated caves, there’s a chance to find brown mushrooms. Break them with your hand or a tool to get them in your inventory.

You can also find brown mushrooms in the form of a huge mushroom. Mine them with your hand or a tool to acquire brown mushrooms.

A Mushroom Fields biome holds the most brown mushrooms, but this biome can be hard to find.

Mushroom Fields biomes are also home to mutated versions of cows called mooshrooms. Red mooshrooms spawn naturally, and turn into brown mooshrooms when struck by lightning. When this happens, you can shear a brown mooshroom to get brown mushrooms.

You might also find brown mushrooms when exploring a swamp or the Nether. Villagers may also trade brown mushrooms from time to time.

How to acquire sugar

The fastest way to acquire sugar is through sugar cane.

You can typically find sugar cane near water. Break it to gather it in your inventory, then make a crafting table.

Place the sugar cane in any square in the crafting table, turning it into sugar.

Witches may also drop sugar when you defeat them.

How to acquire spider eyes

While spider eyes have a chance at spawning in dungeon chests, it’s easier to acquire them by defeating spiders.

Spiders spawn at night when playing Easy difficulty or higher, though you can find them at any time while spelunking underground.

Sometimes, you’ll even come across a dungeon with a spider spawner. A spider spawner is an easy way to farm spider eyes.

Creating The Fermented Spider Eye

Now that you’ve acquired the three ingredients for the fermented spider eye recipe, it’s time to craft it.

Start by building a crafting table.

Interact with the crafting table to open the crafting menu. Then, arrange the ingredients in any order.

Congratulations! You’ve successfully crafted a fermented spider eye. However, this process used up your resources. You’ll need additional sugar, brown mushrooms, and normal spider eyes to craft more fermented spider eyes.

What Can I Brew With Fermented Spider Eyes?

You can brew quite a few potions with the fermented spider eye. But first, you’ll need a Brewing Stand.

You can easily find a Brewing Stand in a village, though you can also craft them.

To craft a Brewing Stand, open the crafting menu and combine a Blaze Rod with three stone of any kind.

Once you’ve crafted a Brewing Stand, you’ll need some Blaze Powder for fuel. You can acquire Blaze Powder in the Nether by defeating Blazes, picking up their dropped Blaze Rods, and breaking it down into Blaze Powder via a crafting table.

Now that you’re all set up, here are four powerful potions to brew with fermented spider eyes.

Potion of Invisibility

The Potion of Invisibility keeps you hidden from other players, though holding items in your hand can give you away. This potion requires one fermented spider eye and a Potion of Night Vision.

This potion can also hide you from mobs, but they will detect you if they get close.

Potion of Slowness

A Potion of Slowness slows players and enemies down when used, making it much harder for them to chase you. It requires a fermented spider eye, a Potion of Swiftness, or a Potion of Leaping.

Higher-level versions of this potion slow targets down even more.

Potion of Weakness

A Potion of Weakness lowers its target’s damage output. It’s made with a fermented spider eye and a basic Water Bottle.

Potion of Harming

A Potion of Harming enacts instant damage, making it super effective during player-vs-player encounters. Create this potion with one fermented spider eye and a Potion of Poison or a Potion of Healing.

Note that these basic potions only apply to those who drink them. If you want to throw these potions at targets, combine them with gunpowder to create a splash potion.

Combine potions with other items for different effects! Redstone extends a potion’s effects, while glowstone dust increases a potion’s level. Experiment to find all new effects!
