The mocha flavored coffee is a refreshing beverage on a hot day when it is too hot to drink a normal, hot cup of coffee. However, there is no real strong pick me up like there is with traditional coffee. It tastes more like chocolate milk than any coffee, so if you like chocolate milk, you will like the mocha flavor.
I wouldn't buy it again because when I drink coffee, I want the taste and effects of coffee. (read caffeine). But maybe if you need a chocolate base for a recipe, this could be a good thing to have.
