The southern Rhône sub-region has a more
Mediterranean climate with milder winters and hot summers. Drought can be a problem in the area, but limited
irrigation is permitted. The differing terroirs, together with the rugged landscape which partly protects the valleys from the
Mistral, produce
microclimates which give rise to a wide diversity of wines. A feature of the cultivation of the region is the use of large pebbles around the bases of the vines to absorb the heat of the sun during the day to keep the vines warm at night when, due to the cloudless skies, there is often a significant drop in temperature. The southern Rhône's most famous red wine is
Châteauneuf-du-Pape, a blend containing up to 19 varieties of wine grapes (ten red and nine white) as permitted by the Châteauneuf-du-Pape AOC rules. Other nearby AOC regions including
Côtes du Vivarais AOC,
Grignan-Les Adhemar AOC,
Lirac AOC,
Tavel AOC,
Vacqueyras AOC, and
Ventoux AOC may contain even more varieties in the blend.
Gigondas AOC, on the other hand, is predominantly made from
Grenache noir and has a more restricted set of permitted grapes. Depending on the specific AOC rules, grapes blended into southern Rhône reds may include Grenache, Syrah,
Mourvèdre,
Carignan and
Cinsaut. Similar wine blends globally are known as
GSM, after the first three varietals. The reds from the left bank are full bodied, rich in tannins while young, and are characterized by their aromas of prune, undergrowth, chocolate and
ripe black fruit. The right bank reds are slightly lighter and fruitier. Southern Rhône appellations: •
