It may well be one of the most traditional wine regions in France: Châteauneuf-du-Pape. Its wines are renowned for their ability to age for decades; they are dark, full and tannic. And they aren't cheap.
If you are looking for a good example of a classic, ageworthy Châteauneuf-du-Pape, Château de Beaucastel is a great example. OUA just might have some in stock, but don't expect them to come cheap. It may be a better idea to buy some in France and bring them back with you.
A number of Châteauneuf-du-Pape producers make wines that are made in a more fruitforward, accessible style. These have less structure and depth, but their great advantage is that they are more enjoyable when young. A good example of this style is the wine is Château Mont-Redon 2006. It is relatively affordable (13.900 OMR at African & Eastern), yet has a bit more to offer than your usual daily drinker. Dark coloured, with lovely dark cherries and plum, supported by a medium tannic backbone, with spices and licorice on the finish. Don't drink it too cool, as some less enjoyable green flavours come to the front. This is great with a leg of lamb. This is not a wine to age for decades, but if you have a wine fridge (and patience) you could try to save a bottle or two to drink in the coming 5 years.
Château Mont-Redon also produces a white Châteauneuf-du-Pape. Once we've tasted that wine, we will report back here.
