I didn't appreciate all of the buzz when this this was released, but now that I have one, I totally get it! This little gizmo takes care of so much stuff and really helped simplify my setup!

Well-made gear!

I’m in the second week of a pressure fermentation on a lager ferment at room temperature, and I must admit that I am incredibly impressed by how well this maintains pressure evenly at the psi I set it to.

Best on the market!

Flipping awesome! Easy to maintain and adjust pressure. Love the CO2 post to keep applied pressure on the vessel when ramping down or cold crashing. Perfect for pressure transfers as well.

Beautiful hefty piece of stainless!!!

I’m making mead, and it turned out to be a bit impractical because it spits all the sanitizer points of the cup. But it’s an awesome prv and I’m sure it’s the right tool for plenty of folks making beer.

Good product, but ....

The PRV is well made and comes with a very prominent warning label about the risk of explosion when used improperly. However, the unit I received came with absolutely no instructions as to how to use it safely! Additionally, the gauge face was filled with a liquid (I'm assuming that it is food grade lubricant) but it did not fill the gauge face completely. Lastly, the gauge needle did not rest on the 0 peg so I'm never sure if the pressure has been completely vented.


The All-In-One PRV is fully adjustable from 0-15psi. Simply twist the top adjustment knob to increase or decrease the pressure inside your fermenter. This allows for use with everything from pressure fermenting, spunding, carbonating or even pressure transfers to kegs. Brew smarter, not harder.

Safety First, Beer Second

CO2 produced by yeast must be handled carefully, otherwise the vessel can become over pressurized, making it very dangerous. This is why a large-port robust PRV is so important. A PRV is designed to automatically vent CO2 gas from inside your fermenter at a set pressure. Since Spike fermenters are designed for 15psi, that’s what the All-In-One PRV is designed to release at. The seal and spring lifts to allow it to escape or “bubble out.”


There’s a lot of PRV options out there, but the Spike All-In-One PRV combines all those features and then some in one sleek design. It has an adjustable pressure release knob, pressure gauge, gas post, quick release plunger and sanitizer cup with drain.

Pressure and Vacuum Release

Not only does the All-In-One have an adjustable pressure release but it also has a 1psi vacuum release and quick pressure release! Done fermenting or need to bleed off pressure? Simply lightly push down on the top plunger to bleed off the desired amount of pressure from your fermenter.

Sanitizer Cup

During development, the number one request from BETA testers was to add a sanitizer cup. The sanitizer cup acts as an airlock to let gas escape but doesn’t let air back in which can cause an infection. The cup also has a built-in quick drain barb so you can quickly and easily drain the sanitizer before depressurizing so you don’t end up getting a sanitizer shower.

1.5” Universal Fitting

We’ve said it before and we’ll say it again—when it comes to safety, bigger is better! The All-In-One PRV uses a huge 1.5” TC fitting, which virtually eliminates the chances of it ever getting clogged. Many competitor PRVs have much smaller openings, which can get clogged with hops or krausen.
