Les Castets sits just underneath Le Ban, and it marks the beginning of a swath of premier crus that form the fillet of the slope above the village itself. Produced from a miniscule 0.3-hectare parcel, it shows more richness on the palate than the Le Ban above, but with a similar vibrancy. Prudhon’s vines here are 15 years old, and they employ a modest 25% new oak, which the premier-cru density of the wine absorbs well.
