Introducing Immersion by BrewJacket

Immersion is the world's smallest lager fermentation device, giving brewers the ability to create world class lagers without a refrigerator. Immersion can bring your beer down to 35º F below ambient in a matter of days and hold it there for as long as it is plugged into the wall. Immersion has the same footprint as your carboy so no additional space is needed to create a lager! Now it is possible to brew a lager in your closet, bedroom, living room, or any tiny corner of your house.
