The Belgian chocolatier Kim's Chocolates has a line of Limited Origin Selection chocolates, featuring cacao beans from a particular country (this one features beans from Costa Rica). The beans are also certified by the Rainforest Alliance, which ensures that production and farming methods are balanced against the needs of the local ecosystem and that these protect its soil, rivers and wildlife; cocoa workers also have access to proper housing, education, medical and safe working conditions. The ingredient listing is good, cocoa mass, sugar, cocoa butter and vanilla (natural flavour). The cacao content is at 71%.
How does it taste? I enjoyed this bar very much, the chocolate was very smooth and melted very well, and had almost a mousse-like texture and taste. I have not been able to locate this again (I bought it in a Chinese Supermarket) but would definitely buy and eat this again.
