Fix Over-Carbonated Beers with a Spunding Valve

A Spunding Valve allows you to maintain a set pressure. If pressure in the vessel exceeds the set point, it is expelled. It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.

Why a Spunding Valve?

There are loads of homebrew related applications for a Spunding valve ranging from pressurized ferementation to naturally carbonating to fixing over carbonated beers and lots more.  Check out our resource post on the subject.  It’s arguably the go-to resource on the Internet on the subject

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.

Ends Today: Kegland DuoTight BlowTie Spunding Valve… $11.99!

15 PSI Duotight Blowtie Spunding Valve with Gauge

DuoTight BlowTie Spunding Valve With Gauge

More Info

From the product description, check product page for current description, price and availability:

The BlowTie is a diaphragm based adjustable spunding valve used to release pressure from kegs and other pressure vessels. It features a usable range of 4 to 15 PSI, and the diaphragm construction means it has a wider pressure range than spring based spundling valves. This unit can be easily disassembled for cleaning using a phillips head screw driver. Accuracy of the gauge is plus or minus 2 PSI.

 

A Spunding Valve allows you to ferment under pressure, naturally and precisely carbonate in the keg, fix over-carbonated beers and lots more. See: Build a Spunding Valve – for loads of information on building and using a Spunding Valve.

BowTie v1 Assembly

BlowTie v1 & v2!

This review covers both the original v1 Kegland v1 BlowTie & v2. Both are DuoTight compatible. The biggest difference is v2 has an integrated gauge, where v1 required an add-on gauge.

Kegland BlowTie v2

But first, more about DuoTight!

Kegland’s DuoTight Fittings are designed to work with EVABarrier Double Wall Tubing.  They offer quick, reliable connections, easy implementation, a variety of fitting options and feature amazing versatility.  They’re also, generally speaking, very well priced.  DuoTights are push to connect fittings and require no tubing clamps.

Canada Edition… Build a Spunding Valve! – How and Why

A Spunding Valve allows you to maintain a set pressure.  If pressure in the vessel exceeds the set point, it is expelled.  It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.

This is a version of our Spunding Valve Build that features components that are generally available in Canada.

Homebrewing Applications of a Spunding Valve

  • Pressurized fermentation.  Ferment in a 5 or 10 gallon corny keg and use your Spunding Valve instead of an airlock.  This allows you to ferment at your desired pressure.
  • Dry hop under pressure.  This allows you to dry hop earlier while reducing oxygenation.  Active yeast are more likely to metabolize oxygen that’s introduced during dry hopping during active fermentation.  Since CO2 is not exiting beer as vigorously under pressure, wanted compounds, flavors and aromas are more likely to stay in your beer under pressure.
  • Naturally and accurately carbonate beer right in the keg.
  • An airlock replacement.  Keep the valve wide open for non-pressurized fermentations.  Only do this if you have plenty of head space.  This wouldn’t make a great blow off tube.
  • Keg to keg transfers.  Use the Spunding Valve to allow excess gas to exit the receiving keg as you transfer under pressure.  Helps you achieve a slow, controlled and pressurized transfer.
  • Fix over-carbonated beers.
  • Test for keg leaks.  Pressurize your keg to serving pressure.  Put the Spunding Valve on (with the pressure set well above your serving PSI) and note the reading.  The gauge should remain steady.  If pressure drops, you know you have a keg leak.  The digital build, see below, is especially helpful for this task,  The digital gauge reads with .1 PSI resolution making pressure changes easy to spot.  It’s worth noting that this checks the entire keg including gas body o-ring.  That spot is hard to check and other way as it’s only in function when the gas QD is on.  When the gas QD is on… it’s difficult to spray and check for bubbles underneath the gas QD.  Thanks to Scott Janish for this tip!
  • As an airlock for long term aging of beers.  Airlocks can run dry over time.  A Spunding Valve will not.
  • Utilize CO2 from fermentation for flushing kegs and fermenters.
