Related to this, can someone remind me what the thing is called that you put on a corny gas out valve to regulate the pressure inside? Setting it to 15 PSI and then it vents when it goes over, until it goes back down to 15?
I typically ferment all of my lagers under some pressure, because I have to ferment them in cornies (not a very big fridge, only two will fit, carboys don't fit, etc). I would be very interested in seeing how fermenting under pressure at ale temps would affect ales. Perhaps a fun exbeeriment?
