A fermentation system includes a vessel defining a chamber for holding liquids and including a lower aperture, an insulating jacket disposed around the vessel, and a cooling fluid disposed between the insulating jacket and the vessel, the cooling fluid being in fluid communication with a fluid pump. A beverage line operably couples the lower aperture with a dispensing spigot, the beverage line being wrapped around the vessel and at least partially submerged in the fluid. The system further includes a collar disposed proximate the conical bottom portion of the vessel, the collar including a gasket in abutting contact with the insulating jacket.
