I recently bought a 10 gallon corny keg to use as a fermenter. It is perfect to ferment lagers in because it is as tall as a standard corny so it fits nicely in my kegerator. In order to use it as a fermenter I simply connect a piece of tubing to a gas ball valve, connect that to gas in, and run that into a growler of sanitizer. It worked perfectly when I fermented my Yellow Sally Pilsner.
On Sunday I used it as my fermenter for my Wader Patch Wit. I sanitized it, racked into it, connected the gas valve to the beverage out post….wha wha what!…The next morning when I walked into the fermentation chamber (basement bathroom), the active fermentation had pumped four of the five gallons onto the floor and carpet.
Quite a mess.
Quite a big mistake.
Not one I will be making anytime soon again.
