The present invention is directed to a stackable container system that includes containers and lids that are configured to allow any of the lids to be used on any of the containers. The bottom of each container interlocks with the top of each lid to allow the containers to be stacked. A handle may also be included that is configured to attach to any of the lids to form a handle for carrying a stack of the interlocked containers. The stackable container system may also include a storage container, such as a beverage bottle, for storing a stack of interlocked containers. Accordingly, each container can be used to store ingredients that are to be later combined in the storage container for consumption. The lids can be configured to be heated or cooled to provide heating or cooling to contents of the container or to the storage container in general.
