The type of water used in brewing is of some importance. Well, spring and distilled waters are preferred over that which pours from the tap. You can buy these bottled or collect them from the source, so long as it’s unpolluted and free running. Rain water is ideal for use — except when gathered in smoggy areas. Tap water can be used as a last resort, but consider purchasing the bottled variety in the future.
Distilled water is used for medicinal preparations, which is fine but not for magickal operations, for it is inert. If you’re going to drink the brew (or even if you’re not), distilled water is definitely better than chlorinated, fluoridated, bacteria-filled tap water. If it’s all you have, use it.
Sea water and mineral water aren’t recommended due to their high mineral content.
