Our Bar of the Week is Michel Cluizel's Vila Gracinda, a 67% dark chocolate named for the plantation on which the cacao was grown.  Vila Gracinda is located on the equatorial island of São Tomé, off the coast of west Africa, where the rich volcanic soil and marine climate have supported cocoa plantations since the early 19th century.  Dried in the sun, these beans maintain their complex aromas and give this chocolate notes of spice and herbs, liquorice and tropical fruit.
