Oxygen Free Transfer and Cold Crash Using a Spunding Valve! – Loads of Updates

homebrew oxygen free transfer

What is Cold Crashing?

Cold Crashing is chilling your beer after fermentation is complete.  Typically you want to get as close to freezing as possible, without actually freezing your beer.  These cooler temperatures cause break, yeast and trub matter to drop out of your beer.  This increases clarity, helps to hasten the conditioning process and helps you get a cleaner transfer to your serving vessel.

What is a Spunding Valve?

A Spunding Valve allows you to ferment under pressure, naturally and precisely carbonate in the keg, fix over-carbonated beers and more.  See: Build a Spunding Valve for more info.

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.

Top Content Countdown… Our 3rd Most Popular Resource Post of 2021!… 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.

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.

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.

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.
