I picked up a bottle of the 2004 Domaine La Colombette Lledoner Pelut (Vin de Pays des Coteaux du Libron) from a local caviste at the height of summer. Even in the hottest weather I can't live without drinking red, but stick to young vigorous wines. As this has some age I resisted broaching it until cooler autumn weather.
I found it balanced and pleasantly mellow. Black cherry fruit with spice and some butch tannins that leaves the side of the palate with a warm slightly chewy but pleasant feel. Good elegant length and lovely to savour.
Does Lledoner Pelut differ from Grenache in taste and quality? One problem here is that there are relatively few Grenache or even Grenache dominated blends made in the region. Roussillon does better and famously Grenache make its vins doux naturels (Maury, Banyuls). Grenache is king in the Southern Rhone but I've tasted few in recent times. The Languedocs I am know vary in style - degrees of oak and ripeness. Grenache seems able to express terroir better than most varieties, which is to say it reveals different subtleties in different vineyards. Conclusion - I find the question more or less unanswerable.
