Northern Brewer All Grain Cooler SystemWeve taken our All Grain Cooler System and added upgrades to provide the best possible brewing experience. The completely redesigned mash lauter tun features thick insulation, a large 12+ gallon capacity and the first ever integrated thermometer. The large capacity will easily handle any 5 gallon brew you can throw its way, from session beers to Imperials, and it's even large enough to accommodate 10 gallon batches up to a gravity of 1. 065.
