Brewtools MiniUni™ Pressure Kit 2.0 - Pressure Fermentation & Serving Kit with Spunding Valve

The MiniUni™ Pressure Kit 2.0 is the upgrade that transforms any Brewtools MiniUni™ tank from an open fermenter into a full pressure fermentation and serving vessel — effectively turning your MiniUni™ into a giant, temperature-controllable corny keg. Mounted on the tank’s 4” TC top port, the kit unlocks the MiniUni™’s pressure rating for fermenting under pressure, natural carbonation through spunding, oxygen-free closed transfers, and serving beer directly from the tank — the complete modern pressure workflow from one kit.

 

What’s new in the 2.0 version is the headline: an updated polyketone housing with a 2” port sized exactly for the Brewtools 2” HopDrop kit — meaning you can dry hop under pressure without ever opening the tank. For hop-forward beers, that closes the last oxygen gap in the process: hops go in through the sealed HopDrop, CO₂ stays in, air stays out, and the aroma you paid for survives to the glass.

 

The kit is genuinely complete. The food-grade composite 4” TC pressure top carries a Brewtools-designed stainless steel mini spunding valve for dialling in fermentation pressure and carbonating naturally, an analog pressure gauge for reading the tank at a glance, and stainless steel ball lock posts for gas and liquid — so standard keg disconnects click straight on for CO₂ supply, closed transfers to kegs, or pouring through a tap. A stainless pull-type PRV gives instant manual pressure relief and doubles as the safety valve. On the collection side, the included 44mm floating ball with silicone tube and tube holder forms a floating pickup that draws clear beer from just below the surface — above the yeast and trub — so what leaves the tank is bright beer, not sediment. Prefer a fixed dip tube? Stainless M16 dip tube pipes are available separately as an alternative collection system.

 

Ferment under pressure within the tank’s rating (1.0 bar operating, 2.0 bar maximum), spund to carbonate, cold crash, and serve or transfer — all without the beer ever seeing air after pitching.
