Despite the "cheeky" reference to the steep slopes and the derrières of harvesters in the name of the vineyard, it's one of only five regional Bourgogne lieux-dits to be allowed a vineyard designation on the label. That steep slope always yields a wine of crunchy Pinot fruit and impeccable balance that Bouvier captures in a bottling that's always one of the best values in Burgundy. Sustainable farming.
