Brewing Stands are used for creating harmful or helpful potions through the process of brewing. To make a potion, at least one glass bottle must be filled with water and added to the brewing stand. Adding a nether wart is often the next step, making an awkward potion. Many different types of potions may then be made from the awkward potion by adding other ingredients.
The player may drink the potion and get back the potion bottle, or throw the potion (if made a splash potion by adding gun powder) at another player or mob for the target to receive the potion effects (effectively destroying the bottle). Other items such as redstone or glowstone dust made be added to a completed potion to change duration or strength, respectively.
