Fix Over-Carbonated Beers with a Spunding Valve

A Spunding Valve can assist with fixing over-carbonated beer.

  • Determine your desired pressure based on temperature and desired carbonation using a carbonation chart.  See: Balancing Your Draft System for a carbonation chart.
  • Pressurize the keg to just over your desired final pressure.
  • Attach the Spunding Valve
  • Slowly dial down the pressure until you achieve your desired pressure – More about setting pressure
  • The Spunding Valve allows excess pressure to vent until the new carbonation level is achieved.
  • You can periodically agitate the keg to fix carbonation more quickly.
