In a 45-minute tour, you'll taste the pure flavor of cacao thanks to Claudio Corallo, an Italian-born agronomist who's made it his mission to produce the world's best chocolate. Claudio lives and grows his cocoa on the tiny island of Sao Tome e Principe -west of equatorial Africa - and he ships his single-estate-grown organic chocolate directly and exclusively to Alegio Chocolate, his store with locations in Berkeley and Palo Alto.
