Chateaux visits in St. Emilion and Right Bank?

Your question must mean the Right Bank in Bordeaux, non?
Some wine chateaux in Bordeaux, for your consideration, would be the Haut-Medoc wine communes/villages:
Margaux
St.-Julien
Pauillac
St.-Estephe
Chateau Lafite-Rothschild

Oui, the right bank of the Gironde, as opposed to the [left bank] Medoc. I'm looking for wineries that people may have visited and found particularly enjoyable - either for their ambiance, or wines, or setting, etc. For instance, areas would include: Blaye, Bourg, Fronsac, Pomerol, St. Emilion, and Côte de Castillion, among others.

I do have several guidebooks of the region, was just looking for reccos from people who have been some, and enjoyed the visit.

Just curious, why are you excluding the Haut-Medoc and Pssac-Leognan (the Left Bank)?

Hi Kent,
we're staying for one week at a house outside of St. Emilion. The five of us are wine geeks and most of us have been to other wine regions in France (Loire, Champagne, Alsace, Burgundy, and Rhone Valley) in the past. We're visiting Bordeaux for essentially the first time and were looking for suggestions. Did you have other areas or regions in mind that we should visit?

As you probably already know from your previous experience wine tasting in France, it's not the same as the typical "Napa Valley" experience.
It will help if someone in your group knows how to explain, in French, what kind of wine(s) you are wanting to taste.
And, of course, you will be expected to buy something, at least a few bottles.
Now, they will know, after you speak, that you're tourists, so they will not expect you to buy a case, but you will need to buy, at least, a few bottles, just good form in Bordeaux.

You will find the difference between Bordeaux wines, and what is available here in the US, to be interesting. The terroir is everything there, not the varietal.

Cognac, some 100km north of St. Emilion?
