Product details

Spunding valve is a must-have for fermenting under pressure or transferring under pressure. A Spunding Valve is used to adjust and release pressure on a pressure-capable fermenter, such as a Unitank. It can also be used to release pressure from a keg while filling or filtering. The relief valve can be adjusted to release pressure from 0-15 psi.

Pressure Fermentation
Pressure fermentation is becoming all the rage in homebrewing, across all levels and proven to significantly reduce esters and levels of diacetyl. But in order to do it accurately and safely, you need a way to release built up pressure. You'll pressurize your vessel to your desired psi, but once fermentation begins and the yeast get to work creating CO2, the pressure inside the vessel will increase. Attach a spunding valve and set it to your desired pressure, and it will blow off when it goes above the set psi and close when it's back to your desired psi.

Pressure Transfers
You may have done pressure transfers from keg to keg during filtering or after fining. While pressure transferring, it's a good idea to have a bit of head pressure in the receiving keg, especially if you're transferring beer that is already carbonated. Having a spunding valve in place will allow you to control the pressure and give you more consistent results, without losing carbonation in the process and creating a foamy mess.

Additional Uses:

  • Fix over carbonated beer.
  • Leak test Kegs.
  • Natural Carbonation in Keg.

Spunding Valves should never be used as the main prv. Every vessel that is under pressure should have a primary prv set in accordance with the manufacturer. Northern Brewer Spunding valve should only act as a secondary prv, and should only be used within the safety limits of the vessel.

Pressure fermentation

Takes a little bit of tinkering or trial and error to use correctly if you've never used one. Adjusting the desired pressure release was initially a little tricky and finicky. But does the job. Used it to make a Pilsner so far and came out great!

Arrived quick. I threw together a 'kitchen sink' ale from leftover gains and fermented at 14psi for a few weeks. Turned out really tasty and didn't have to manage temps- no off flavors at all. Highly recommended. Thanks NB.

Spunding Valve

I received my spunding valve in a timely matter and was excited to use it! I had a new corny keg to pressure test, so I decided to start there. Right away there was an issue: the pressure relief valve wasn't working properly - or at least, not in the way I would have liked. Even with the valve completely closed, it was still venting gas, and this was below 10psi! Obviously, the PRV was no good. I've dealt with Norther Brewer customer service before, and they're excellent, but I also didn't like the adjustability (or lack thereof) of the PRV, so I decided to just purchase a new PRV to replace the old one. Once I did that, the spunding valve worked like a charm. I could confidently pressure test my new corny kegs, and I'm currently fermenting a batch under pressure.

I don't think it's a bad spunding valve, but there's definitely room for improvement. Adjustability of the PRV would be my No.1 recommendation. You can, of course, replace this part pretty easily. If you do, I would recommend a diaphragm valve over the spring style. Another improvement would be stainless steel construction. Brass just doesn't want to hold up. Every time I've had to take this valve apart, there's been tiny brass shavings on the table I work over - no matter how gentle I am.

It works, but it could be better out of the box. If the stock PRV is always an issue (like mine was), then it's really a one or two star rating. I'm assuming my PRV was bad, so I gave three stars because it would still be usable out of the box, just not as good as it could be with a couple tweaks.
