Description

Cask Beer CO2 Aspirator / Breather Valve

Venting lets the carbon dioxide still being produced inside a cask escape in a controlled way, so the beer settles to the right condition instead of gushing or going flat.

The supplier lists no dimensions for this item. Ask us and we will confirm the details you need rather than guess at them.

Before you order

  • Soft spile first to vent, hard spile once the bubbling has stopped
  • If pressure builds again, go back to a soft spile rather than forcing it
  • Wooden spiles are single use — porous wood cannot be sanitised

There is a fuller explanation of how to choose on the cask venting & conditioning page.

Questions about this product

What is the difference between a soft spile and a hard spile?

A soft spile is porous and lets gas escape slowly, which is what you want while the beer is still conditioning. A hard spile is solid and seals the cask, holding the remaining condition in the beer until it is served.

How long should a cask vent for?

Until the bubbling stops, which depends on the beer and how warm the cellar is. It can be a few hours or it can be two days. Time is a poor guide u2014 watch the cask, not the clock.

Can I reuse a wooden spile?

No. Wood is porous, which is exactly what makes a soft spile work, and it is also what makes it impossible to clean properly. Use a fresh one on every cask.
