I had been thinking about using a couple corny kegs as fermentors. Maybe even trimming up some dip tubes to be able to CO2 push finished beer out of the kegs to clean serving kegs. Here are some of the things I am concerned about.
Using the standard gas out port for my airlock set up (tubing and a water jug), may have more restriction than I am used to. A source of regular clogging perhaps?
The corny keg only holds about 5.25 gallons. This almost ensures the need to blow off every time, and as stated in part 1 cleaning that narrow a diameter tubing would be a pain each time. The fix would be 4 gallon batchs. I nice idead for experimenting with recipes, but my mash tun and boil kettle are all somewhat optimized for 10 gallon brew sessions. Do I really want to ferment in two kegs for each batch?
The stainless keg is a superior container for sure. Light, easy to move, relatively indestructable. But I'd be competing for keg fermentor space all the time vs. keg serving space.
Fermenting in Corny kegs just doesn't seem to have a enough plus sides. Am I missing any?
