The bottle shape is a replica of a cocktail shaker with a functional lid that doubles as a shot measurement. The stars in Starbucks logo are echoed in a reverse color band around the bottom of the bottle lid. Dark espresso replaces the traditional silver color of the “shaker” to evoke the deep, rich coffee for which Starbucks is famous.

The product itself is derived from actual Starbucks coffee (100 percent to be exact), combined with 20 percent alcohol. An informal survey of Starbucks customers and liquor store managers uncovered nothing but rave reviews for the taste of the product, regardless of whether it was mixed with coffee, other drinks or on the rocks.
