To make a Potion in Minecraft, you need these things: A Brewing Stand for brewing potions. Blaze Powder for fuelling your Brewing Stand. Glass Bottles to contain your Potions. A Water source nearby (Cauldron or Water block). Every potion starts with a Water Bottle. To make a Water Bottle, just right-click on a water source with a Glass Bottle in your hand. There are three steps to making a Potion: Make an Awkward Potion (Water Bottle + Netherwart) in the Brewing Stand. Add an effect ingredient to specify the Potion effect. (Optional) Add one or more modifier ingredients to change the nature of the Potion.
