A thermal barrier liner maintains a beverage within a container at a desired temperature. The liner may include a closed cell substrate, a base layer having gas or liquid filled microcapsules, a base layer having microencapsulated solid-liquid phase change material, or combinations thereof. In other embodiments, an integral cooling element incorporates solid/liquid phase change material. The cooling element can either be attached to the exterior of the container, the interior of the container, or free-floating within the container. Other embodiments include container holders or direct beverage holders incorporating phase change materials to control temperature of the beverages. The embodiments may further include thermochromatic ink to provide a visible color indication of temperature changes for the beverage.
