Indeed there is a regular (i.e. non-kosher) version of the Chateau Le Crock which as a possible point of interest is owned by the same family that has Chateaux Leoville Poyferre and Camensac. The family also produces Chateau Moulin RIche and Pavillon des Connetables (respectively the second and third wines of Leoville Poyferre). For ease in comparison, the tasting notes for the 2003 kosher and non-kosher edition follow.
Chateau Le Crock, St-Estephe, 2003 (Kosher Edition): Dark garnet with purple and orange reflections, full-bodied with still gripping tannins needing time to settle in. On the nose and palate blackberry, currant and black cherry fruits, those on a background of Oriental spices and olives. On the finish hints of licorice and citrus peel. Best 2009-2012. Score 89.
