Among the top ten most planted varieties in the world, grenache is a black variety originally from Spain (called garnacha) and mainly grown in Spain and France. Its a drought resistant variety, early budding but late ripening and therefore suited to warm to hot climate.
What's the profile of grenache ?
red fruit flavours (strawberry, redcurrant) and notes of white pepper, aromatic herbs
Considering this profile, 100% grenache wines can lack colour intensity and some acidity to reach balance (except Château Rayas, amazing grenache wine from Châteauneuf-du-Pape). That's why grenache will often be blended with other varieties. A common example is in southern Rhône Valley (ex. AOC Châteauneuf-du-Pape, AOC Gigondas, AOC Vacqueyras), where syrah and mourvèdre are blended with grenache to provide colour intensity, acidity, tannins, black fruits aromas and extra notes of spices. More balanced, structured, concentrated and complex wines can reach higher quality levels and longer ageing potential.
Some other famous examples of wines including grenache in their blends:
Spain: DOC Priorat, DO Montsant, DOC Rioja
France: AOC Côtes-de-Provence, AOC Terrasses du Larzac, AOC Corbières, AOC Fitou, AOC Banyuls (Vins Doux Naturels)
Italy: DOC Cannonau di Sardegna (cannonau is the local name for grenache)
Barrosa Valley and McLaren Vale in Australia
