This chocolate bar from the German chocolatier Trumpf has 74% cacao content and features mint flavouring. The ingredient listing looks good, cocoa mass, sugar, cocoa powder, mint crunch (sugar, cocoa butter and peppermint oil), soya lecithin and flavouring.
How did it taste? I didn't and don't care for the peppermint crunch, but this was fairly good chocolate, and I occasionally like mint with my chocolate. I don't think I would buy this bar again.
