How to Prepare a Pin Cask

So, you’ve got yourself a pin cask and you’re ready to serve your beer the traditional way. Here’s a step-by-step guide to get it prepped and ready to pour.

What You’ll Need

  • A pin cask of beer (usually 4.5 gallons)
  • Wooden or plastic shive (for the top opening)
  • Wooden or plastic keystone (for the front hole)
  • Spile (hard and soft)
  • Mallet or rubber hammer
  • Tap

Step 1: Fit the Shive

Insert the shive into the top hole of the cask and hammer it in firmly with the mallet. This seals the cask but gives you a spot for venting and later inserting a spile.

Step 2: Fit the Keystone

Place the keystone into the front hole of the cask and hammer it in tightly. This is where the tap will eventually go.

Step 3: Rest the Cask

Lay the cask on its side with the shive hole facing up. Ideally, do this 24–48 hours before serving to let the beer settle.

Step 4: Vent the Cask

  • Insert a soft spile into the shive to allow excess gas to escape.
  • Listen for the hiss — once it quiets down, the beer is properly vented.
  • Replace the soft spile with a hard spile to keep air from entering.

Step 5: Tap the Cask

  • When you’re ready to serve, remove the hard spile and insert the tap through the keystone with a few firm mallet strikes.
  • Beer will now flow when the tap is opened.

Step 6: Serving Tips

  • Keep the cask cool (ideally around 50–55°F).
  • Swap between hard and soft spiles as needed:
    • Soft spile → lets CO₂ escape while serving.
    • Hard spile → seals it when not pouring.
  • Drink it within a few days for the freshest pint.

Final Thoughts

in Cask ale is a beautiful thing — natural carbonation, smooth mouthfeel, and traditional character. Prepping a pin cask the right way makes all the difference, so take your time with venting and tapping. Then enjoy sharing pints with friends, the way it was meant to be.
