Mark Garber owner of Lancaster Homebrew explains in this video how to rack beer. Racking beer is the process of siphoning your beer off of the sediment after it has fermented. You need a way to take the beer and leave the sediment in preparation for the bottling process. As with all steps of beer brewing, sanitation is of key importance. Mark reviews the sanitation process before presenting two methods that you can use to start the siphon when you are racking beer.
