Valrhona, the Rolls Royce of chocolate, has been crafting couvertures (chocolates with high cocoa content) since 1922. Hailing from France's Rhône Valley, Valrhona's wine country influence is unmistakable. The label on each Valrhona cru (single origin bar) bears the name of that bean's terroir, the most exclusive of these being the Vintage Single Origin bars, sold in limited quantities according to crop yield.
