On the second night, the hard tannins in the 2005 Reserve Grand Veneur Cotes du Rhone (reported on below) had mostly integrated with the deep-running fruit. It's a very nice wine with concentrated dark cherry flavors. Yet I still prefer the 2005 Grand Prieur--for its price, immediacy and breadth of fruit flavors and aromas.
Other 2005s from the Southern Rhone that I like include: Domaine Sainte Anne (lovely forward blueberry fruit but with stuffing to carry it for years); Domaine de la Janasse (similar to the Sainte Anne in many ways but more reserved at this stage); Domaine du Vieux Chene (either the Cuvee du Cappucines or the Haie au Grives); Paul Jaboulet's Parallele 45; and La Vieille Ferme Cotes du Ventoux.
I haven't bought any 2005 Chateauneufs or Gigondas, but I'm assuming that they will be very good.
