A beverage container includes a hollow container with a first reservoir and a second reservoir positioned within the hollow container, the first reservoir configured to store an aqueous beverage, the second reservoir sealingly storing one or more polymer matrices that include cannabinoid compounds, the second reservoir being configured to release the one or more polymer matrices into the aqueous beverage subsequent to the second reservoir being opened, the hollow container defining an opening through which a liquid in the hollow container is allowed to egress from the hollow container. The beverage container also includes a closure sealingly and operably coupled with the opening of the hollow container, the closure operably coupled with the second reservoir such that opening of the closure initiates opening of the second reservoir, the closure sealing the opening of the hollow container. Methods of using the beverage container and preparing a beverage containing cannabinoids are also described.
