In the Southern Rhône, prices, while escalating, have generally remained at fairly modest levels in the grand scheme of things. Yes, the price of Châteauneuf has risen steeply, from about $20 a bottle to over $50 in many cases, but there is one producer whose wines have always been at the very top of the scale in the South, and that would be Henri Bonneau.
This is a small estate, and the production is split between a few wines. There are potentially four labels that can be used, each signifying a better level of quality than the one it follows. They are the Henri Bonneau, the Marie Beurrier, the Reserve des Célestins, and the ultra-rare Cuvée Speciale. A 2006 Reserve des Celestins will set you back a rather modest $225 a bottle, though if you search for a Cuvée Speciale you might track down a bottle of the 1998, the last vintage released, and feel lucky you found it for less than $400 a bottle!
