One of my favourite chocolate bars is the Ecuador bar from the Italian Chocolatier Speciale Italia srl. This one, the fourth I have tried, a Spicy Chocolate with a cacao content of 68%, contains coffee as a flavouring (I have seen both ground coffee and espresso offered from Speciale Italia; no doubt they use their own brands in this chocolate bar). The ingredient listing is good, just cocoa paste, sugar, low fat cocoa powder, cocoa butter, coffee, instant coffee and soy lecithin (as an emulsifying agent).
How does it taste? Quite good, the underlying coffee is interesting and enhances the flavour of the chocolate. Notice, too, the plastic bag, very different than many chocolatiers, who normally use foil. I liked this almost as much as the Ecuador bar. I would definitely buy this again.
