This model is nice because it’s USB powered. USB power blocks are easy to be had. That means no manual wiring and no guessing voltage. And, generally speaking, it’s not as expensive as some of the pre-wired options out there. This also has a speed control. That could potentially be useful for stir plate projects although I have no idea if it would offer the granularity needed for that sort of project.

Build a Spunding Valve! – How and Why

June 26, 2024

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.

Install a Priming and Purging Port for Easy Homebrew Pump Operation

pump priming port

Updated: 6/18/2024

I use my March Pump to recirculate/vorlauf, transfer wort to my brew kettle, chill with a recirculating immersion chiller and transfer to my fermenter.  It works great, helps me chill down very quickly and overall, it shaves a significant amount of time off my brew day.

Losing Prime, Cavitation and Clogs

When I first started using this pump, I struggled with it.  It continually lost prime and, less often, clogged with grain material.  Disassembling the pump head is not what I consider a real time saver.  That’s no good!

Building a Dry Hopper for Corny Kegs – Dry Hop Under Pressure!

Thanks to /u/NachoTacocat on r/homebrew for this photo and build info!

Benefits of Fermenting Under Pressure + The Challenges of Dry Hopping Under Pressure

Fermenting under pressure has some great benefits. One of the challenges that using this method presents is… dry hopping. When fermenting under pressure the beer is carbonated. Adding dry hops to a fermented and carbonated beer, especially one at relatively warm fermentation temps equates to a Mentos+Diet Coke sort of situation. The hops provide lots and lots of nucleation points that can cause the beer to erupt expelling foam all over the place in the process denaturing head retaining proteins.

FermZilla fermenters from Kegland have a ready made solution called the Hop Bong. It allows you easily dry hop under pressure. Since the beer and dry hops are under pressure you don’t have foaming problems when dry hopping.

Some carbonation cap models are universal fit and some work only with gas posts.  For draft line cleaning projects to work well, at least in my opinion, the carb cap that’s used needs to be universal. As of this posting, the product page says this works with both liquid and ball lock posts.  Check the product description for current specs.
