A bottle adapter includes a connector having a containment region for holding a composition and an internal threaded portion that engages threads on a bottle neck and has an opening in fluid communication with the containment region. An upper end of the connector has an aperture that is in fluid communication with the containment region. The adapter also includes a first seal for sealing an opening in the threaded portion and a second seal for sealing the aperture. In use a removal of the first seal permits fluid communication between the containment region and fluid in the bottle, permitting the formation of a mixture. A removal of the second seal permits the mixture to be dispensed. Methods for storing a composition for subsequent mixing with a fluid and for delivering a mixture of a composition and a fluid are also addressed.
