Lagering has always been tough. Keeping the beer at 48 degrees thru fermentation, then letting it warm up to a diactyl rest, then slowly ramping down as cold as possible to lager. The internal chiller on the Brewhemoth works great to 20 degrees below ambient, then what? This model should lower ambient 20-30 degrees! 100 foot coil of tubing surrounding the Brewhemoth, well insulated with 25 degree liquid flowing thru it. Just what the doctor ordered!
