Rauchbier (Awesome Atavism)

The biggest trick to making a good rauchbier is getting a clean smoke character, one in which chlorine compounds from your water don’t react with the smoky phenols to make odd flavors and aromas. To avoid this, carbon filter your water and — because carbon filtration may not remove all the chlorine compounds in your water — treat your brewing liquor with one crushed Campden tablet per 20 gallons (76 L).
