a reservoir configured to hold a heat exchange fluid;
an evaporator coil arranged within the reservoir, the evaporator coil comprising:
a plurality of windings configured to circulate a coolant, and
projections extending from an exterior surface of one or more of the plurality of windings,
wherein the projections each comprise a body defining a plurality of pores configured to permit the heat exchange fluid to flow through the plurality of pores to facilitate formation of a bank of frozen heat exchange fluid on the windings and on the projections when the coolant is circulated through the plurality of windings; and
a chiller coil comprising windings arranged in the reservoir, wherein the beverage is configured to flow through the windings of the chiller coil,
wherein the windings of the chiller coil have a shape that corresponds to a shape of the reservoir, and
