Description
Built for turning around a lager in about a week: ferment at roughly 17 to 20 C under 6 to 15 PSI of spunding pressure, then cold condition for five to seven days. The head pressure suppresses esters, so the beer stays clean despite ale-range temperatures. Frees up tank time on a fast schedule.
