Near to Bonnieux are a couple of vinyards of interest:
Jean-pierre et Nathalie MARGAN at
Château la Canorgue
Route du Pont Julien
which specialises in organic wines. This was the Chateau which featured in a recent film 'A Good Year' . We tend to drink the white, well chilled, as an apero and
Chateau de l'Isolette
(Micheline and Luc Pinatel
Laure Pintel-Gilles and Dennis Gilles)
Route de Bonnieux 84400 Apt
which has a wider range of wines (and an outlet on the D900 main road on the western outskirts of Apt just past the Leclerc and Simply Market supermarkets).
Both Domaines are staples in local restaurants. For every day (and cheaper) drinking don't dismiss the local SYLLA co-operative which has some pretty useful Cotes de Luberon and Cotes de Ventoux wines. It too is on the main D900 next to the Simply Market.
For the best Southern Rhone wines it's necessary to go to the heartland around Gigondas and Vacqueras....about one to one and half hours from St Saturnin (go over Mt Ventoux en route if the sky is clear, superb drive).
If you're a bit pressed for time the larger villages have Caveau in their centres, with tastings, which sell the wines of most of the local producers at the same prices as the Domaines. There's one in Gigondas, another in Vacqueras and again in Beaumes de Venise and I seem to remember that both Rasteau and Chateauneuf de Pape boast one though the latter doesn't sell the product of the top Chateau, Beaucastel.
A few Domaines where we have good tastings over the years:
Rasteau: Domaine La Soumade, Domaine Bressy Masson
Vacqueras: Clos de Cazaux (english spoken by Jean-Michel Vache the proprietor)
:Domaine Le Gayan, Domaine La Fourmone, Domaine du Pesquier
CdP: Domaine de la Janasse, Domaine de Christia (tastings at Courthezon)
A good reference for Rhone wines is the Danish site www.chateauneuf.dk which has background on many Domaines and links to their internet sites. Fortunately the Danish site has an English translation, just as well as despite following 24 episodes of 'The Killing' on BBC our Danish is still not that hot!!
