Which type of chocolate has the highest cocoa content?

Dark chocolate is distinguished by its significant cocoa content, typically ranging between 50% to 90% cocoa solids. This high level of cocoa not only contributes to a more intense chocolate flavor but also provides various health benefits associated with cocoa, such as antioxidants.

Bittersweet chocolate, while also having a higher cocoa content than milk chocolate and white chocolate, generally contains less cocoa than many varieties of dark chocolate, which is designed to emphasize the cocoa taste. Milk chocolate has even less cocoa and is sweeter due to its higher sugar and milk content. White chocolate does not contain cocoa solids at all; it is primarily made from cocoa butter, sugar, and milk solids, which is why it lacks the richness and depth of flavor found in chocolates that derive directly from cocoa.

Thus, dark chocolate stands out as the type with the highest cocoa content, making it the correct choice in this context.
