A syphon tube with a racking cane and sediment trap.
A syphon is needed to move beer from one vessel to another without splashing and oxidising the beer. Using a syphon to transfer beer from the fermenter to the bottling bucket means little to no oxygen is picked up by the beer which could potentially affect the taste.
The racking cane is attached to the end of the syphon so when you are transferring the beer no yeast or hop sediment is picked up. This means your beer will be clearer in the bottles and all the yeast can be left in the fermenting vessel.
This racking cane has clips to both clip the syphon to the bucket and a clip to control the flow of the syphon.
