This is one of the few chocolate bars from Green & Black's that I had not tasted yet. The espresso part comes from Arabica coffee beans, ground as fine as the cacao. This is an intense coffee flavour chocolate bar. The cacao content is at 67%. The ingredient listing is good (all save the lecithin are Organic), chocolate liquor, raw cane sugar, cocoa butter, coffee, soy lecithin (emulsifier), vanilla extract and whole milk powder.
How does it taste? Like drinking a cup of coffee. I'm exaggerating, but it is a strong coffee, or espresso, flavour, so, if you don't like coffee, then this bar is not for you (the strong flavour comes from freshly roasting the coffee beans, then grinding them so fine that the tongue can not distinguish between the chocolate and the coffee). I do like coffee, but most of the time not in a chocolate bar. This is good quality chocolate up to the standards of Green & Black's. I don't think I would get this bar again.
