A Cafe mocha or Mocha is a variant of a caffe latte, but a
portion of chocolate is added, typically in the form of chocolate syrup. When
bought from a vending system, instant chocolate powder is used. Mocha's can
contain dark or milk chocolate.
At the simplest level, a Cafe Mocha means either adding chocolate to your coffee, or adding a shot of espresso coffee to your hot chocolate. In the latter case, the best Cafe Mocha is not made with drip-brewed coffee but rather Italian-brewed espresso.
There are many reasons why espresso is a better complement to chocolate than regular-brewed coffee. Espresso has more 'opposing' taste characteristics for a balanced but bold flavor. If you simply add chocolate to your coffee, there won't be as much flavor in the coffee that counters the chocolate and it will end up tasting like an 'off' mix of the two.
