A wooden shive bung is the most traditional option for closing off the shive in your cask ale dispensing set-up. * It performs well because as the wood takes in moisture it naturally expands to create a tighter seal. * Just insert this bung into the shive on the side of your cask until youâ€TMre ready to use your hard and soft spiles to properly vent the gas and condition your cask ale.

• Made of wood.
• Fits easily into shive of cask.
• Wood expands with moisture to help create a tight seal.
