Minecraft wiki entry for Shelters, associated text: Once you've been to the Nether and gathered some blaze rods, you can create a Brewery, which is simply a room with a brewing stand and a cauldron (however an infinite water source works just the same and doesn't run out). It is great to be able to brew some potions to prepare yourself for leaving your base. Include a chest with some potion ingredients such as sugar, redstone, blaze powder, nether wart, glowstone dust, spider eyes, magma cream, fermented spider eyes, glass bottles and a well as it is an unlimited water supply.
