The premier cru is from a single-hectare plot, uniquely positioned above the left bank of the Serein River. Its steep, well-drained Kimmeridgian slopes and dry winds force the vines to struggle, producing wines of great concentration. The vines average 55-years old.
 

After very strict selection at harvest, grapes are pressed very gently in a pneumatic press, the must is allowed to settle naturally and is racked 12-24 hours after pressing.  Fermentation takes place in temperature-controlled, stainless steel tanks for 4-6 months, and sedimentation occurs naturally.  The wine then ages a further 6+ months on its fine lees.
