Abstract: Disclosed herein are embodiments of a temperature-regulating containment system for actively heating and/or cooling a liquid to a desired liquid temperature, and methods of making and using such a temperature-regulating containment system, whereby the temperature-regulating containment system comprises: (i) a container having an internal cavity defined by a sidewall upwardly extending from a bottom wall, the internal cavity configured to contain liquid which has a liquid temperature; (ii) a temperature regulator operatively coupled to the internal cavity, the temperature regulator configured to regulate the temperature of the internal cavity and the liquid therein; (iii) a pressurizable chamber disposed between the internal cavity and the temperature regulator; and (iv) a pressure regulator operatively coupled to the chamber, the pressure regulator configured to regulate the pressure of the chamber.
