Campden Tablet: 25 tablets

Want to make a major improvement to your beer for about a penny a batch? 1/4 of a campden tablet will immediately remove all the chlorine and chloramine from 5 gallons of brew water.
While chlorine can be boiled off, chloramine cannot. If left in your brew water you can end up with a plastic/band aid flavor in your finished beer. It's the number one flaw we see at the brewoff. Isn't it worth a penny to improve your beer?
Also very useful for sanitizing in winemaking.
