A fluid cooling apparatus includes a first cooling portion have a first series of cooling elements with first cooling surfaces. A second cooling portion can have a second series of cooling elements with second cooling surfaces. The second cooling portion can be removably nested together with the first cooling portion such that the first and second cooling surfaces of respective first and second series of cooling elements can be positioned adjacent to each other with gaps therebetween to form cooling cavities for cooling fluid introduced into the cooling cavities.
