Mocha

Mocha coffee is named after the port of Mocha in Yemen. Marco Polo first brought the mocha coffee beans, which are derived from Arabica coffee beans, to Europe. It is thought that at that time, the beans tasted of chocolate. Nowadays, they don't taste of chocolate, which is presumably why the modern mocha is a mix of coffee and chocolate.

The drink in the picture is the first mocha coffee I've had where the taste of the chocolate comes through as chocolate rather than as just sweetness. The chocolate was dark and bitter, though, so I'd probably add a little sugar if I had it again.

It was in Harris and Hoole in Tesco.
