Do I need a secondary fermentor?
The longer the beer will be fermenting, the more benefit you will see from racking (transferring) your beer to a secondary fermentor. Once the heavy fermentation has ceased, a large amount of sediment accumulates on the bottom of the fermentor. The sediment can contribute to harsh flavors if it is contact with your beer for long (3 or 4 weeks) periods of time. If you rack to a secondary container, take care not to siphon every last drop because you will siphon up the sediment and it will defeat the purpose. If you are making a lager, you probably will not get satisfactory results unless you rack to a secondary.
