Plastic Cask Shives with Membrane (10 Pack)

An Essential Component of Every Cask

The shive is one of the most important components of a traditional cask. Fitted into the larger opening on the top of the cask, it provides access for venting, conditioning and cellar management while maintaining a secure seal during storage and transport.

These clear plastic shives feature an integrated membrane and are designed for use with standard cask-conditioned beer systems, making them ideal for homebrewers, beer festivals, clubs and traditional real ale dispense setups.

Whether you’re filling a 4.5 Gallon BevCask or a 9 Gallon Firkin, a correctly fitted shive is essential for successful cask conditioning and serving.

What Is a Cask Shive?

A shive is the larger bung fitted into the top opening of a cask.

It creates a secure seal during filling, conditioning and transport while also providing the access point used for venting and inserting spiles during cellar preparation.

The membrane allows a cellar person or brewer to pierce the shive safely when preparing the cask for service.

How Does a Shive Work?

The shive is fitted into the designated opening on the crown of the cask.

Once beer has been conditioned and the cask is ready for service, the membrane can be pierced and a soft spile inserted to begin venting. Once the beer has reached the desired condition, a hard spile can be used to help maintain the cask during serving.

This traditional process remains at the heart of real ale dispense.

Why Is a Shive Important?

Without a properly fitted shive, a cask cannot be conditioned or managed correctly.

The shive plays several important roles:

• Seals the cask during conditioning
• Maintains pressure within the vessel
• Provides access for venting
• Allows soft and hard spiles to be used
• Supports traditional cask dispense procedures

Every cask requires a correctly fitted shive before conditioning and serving can take place.
