The Wine Advocate says:
The 2010 Hermitage La Petite Chapelle is a better wine than nearly every Hermitage La Chapelle made under the final years of the Jaboulet family’s ownership (for example, 1993-2005). The 2010 was aged in barrel and represents one-third of the Hermitage crop (another one-third was eliminated and the final one-third went into La Chapelle). Its deep purple color is followed by notes of camphor, tar, pepper, beef blood, black currant jam and hints of new saddle leather as well as earth. This supple, rich, full, authoritative beauty should drink well for 15-20 years.
Again, Vinous rates it even higher:
Opaque ruby. Heady aromas of black and blue fruits, Indian spices and candied flowers. Stains the palate with intense cassis and blueberry flavors, picking suave floral and spice nuances with air. Shows excellent clarity and energy on the finish, which features smoothly integrated tannins and a seductive floral quality.
