The Rhone Valley is France's second-largest AOC wine producer. Almost half of the region's production is bottled under the regional Cotes du Rhone AOC, offering tremendous value and consistent quality. The region's wines have risen 64% in export value over the past decade while volume increased just 9%.

Key Regional Characteristics

  • Continental meets Mediterranean: A collision of north and south expressed in food and wine culture
  • Lyon: The culinary heart of France with more Michelin-starred restaurants than any city outside Paris
  • Granite meets sedimentary: Massif Central (west) collides with Alpine foothills (east)
  • The Mistral: The defining wind that shapes viticulture throughout the valley
The 45th parallel runs through the Rhone Valley — halfway between the equator and the pole. Paul Jaboulet Aine's wine "Parallele 45" references this latitude.

Production Trends (2009-2019)

Viticultural History

600 BCE
Phocaeans (Greeks from Asia Minor) settle Marseille and initiate formal viticulture, trading wine along the Rhone River
121 BCE
Romans arrive and plant the steep Northern Rhone slopes, converting them to terraces before developing the flatter Southern plains
1309-1376
Papal Palace moves from Rome to Avignon — seven French Popes govern the Catholic Church from France
1650
Regulations introduced to guarantee origin and quality of "Coste du Rhone" wines
1737
King Louis XV issues edict enforcing branding of all Coste du Rhone barrels with "CDR" to prevent fraud
1870s
Phylloxera arrives — Mourvedre (1/3 of Southern plantings) loses ground to Grenache and Syrah due to rootstock compatibility issues
1956
Devastating winter freeze (-15°C for three weeks with 60 mph Mistral) destroys olive and fruit trees — many farmers turn to viticulture
1990s
"Rhone Rangers" in the USA and Australian Shiraz/Viognier blends bring international attention to Rhone varieties
Pope John XXII (second of seven Avignon Popes) built a summer residence 11 mi/17.7 km north of Avignon, known as "Chateauneuf-du-Pape" (new castle of the pope). The wines were first called "Vins du Pape."

Mourvedre's Decline

Before phylloxera, Mourvedre represented one-third of Southern Rhone plantings. Finding a suitable rootstock partner took decades, allowing Grenache and Syrah to dominate. Today, Mourvedre represents only ~4% of Cotes du Rhone plantings.

Geography & Climate

Location

The Rhone Valley is situated in southeastern France, bordered by:

  • North: Lyon and Beaujolais
  • Southwest/Southeast: Languedoc and Provence
  • East: The Prealps
  • West: Mountains of the Massif Central

The Rhone River

Begins as glacial meltwater in the Swiss Alps, pours into Lake Geneva near Montreux, then travels southwest through the Jura Mountains to Lyon. There it joins the Saone and pivots southward, streaming through narrow Northern gorges before sweeping onto Southern plains toward the Mediterranean. Total drop: 6,000 ft/1,800 m over 505 mi/813 km.

Climate Comparison

Climate TypeContinental + MediterraneanMediterranean
Sunshine Hours~2,350/year2,600-2,800/year
HazardsFog, spring frost, autumn hail, snowDrought, violent storms, flooding
Ripening WindowShorter — early varieties neededLonger — late varieties possible

The Mistral is the defining climatic factor of the Rhone Valley. On April 6, 2003, it reached a record 72 mph/116 kph — only 1.25 mph less than hurricane force.

The Mistral's Effects

  • Northern Rhone: Steep slopes on narrow riverbanks intensify the moderating river effect; vines trained to stakes (echalas) on south/southeast-facing slopes to minimize wind exposure
  • Southern Rhone: Open plains expose vines to full force; sturdy vines like Grenache are trained in gobelet close to the ground and often lean south from persistent wind pressure

Climate Change Effects

  • Average temperatures increased 2.5°F/1.4°C over the last century
  • Harvest moved forward 15 days in last 26 years
  • Potential alcohol increased 0.6% while acidity dropped 0.5 g/l
  • Producers planting at higher elevations
  • Shade panels and morning misting being tested

Geology, Topography & Soils

Northern Rhone Geology

The Northern Rhone forms part of a rift valley system created when the Alps rose. The Rhone Glacier widened and deepened this valley during the last Ice Age, creating a steep gorge with gradients up to 60°.

Northern Rhone Soils

Granite Subsoils Decomposed Mica Schist Granitic Sands Occasional Limestone

Crozes-Hermitage also has pockets of galets, clay, and loess/molasse. Hermitage contains some clay and sand.

Stony soils radiate trapped heat back to vines as the sun sets, extending photosynthesis and boosting ripeness. Limestone, clay, and sandy soils (cooler) are typically planted to white varieties.

Southern Rhone Geology

The Southern Rhone's broad rocky plains were created by the Rhone Glacier and its tributaries during the last Glacial Maximum (26,500-20,000 years ago). Limestone peaks formed when the Alps pushed skyward:

  • Mont Ventoux and Luberon Massif — eastern border
  • Dentelles de Montmirail — shelter for Gigondas, Vacqueyras, Beaumes de Venise
  • Alpilles — southern horizon near Avignon

Five Principal Southern Rhone Soil Types

Galets (river stones) Garrigue (limestone) Sandstone Clay Loess/Molasse
Galets (large rounded river stones) are the signature soil of the Southern Rhone, especially Chateauneuf-du-Pape. They absorb heat during the day and radiate it back at night, aiding ripening.

Grape Varieties

Inter Rhone records 34 grape varieties planted throughout the Rhone Valley. Twenty-three may be incorporated into Cotes du Rhone AOC wines.

Northern Rhone — Red Grape

Syrah is the sole red grape of the Northern Rhone. It is reductive in nature, so care must be taken to avoid excessively gamey, barnyard notes.

Northern Rhone — White Grapes

GrapeRoleCharacteristics
ViognierAromatic, co-fermented with SyrahAdds perfume and color intensity
MarsannePrimary white blend componentHigher extract levels; also co-fermented with Syrah
RoussanneAromatic blending partnerAdds perfume to both whites and reds
When Viognier is co-fermented with Syrah, it paradoxically helps SET color (not lighten it). Viognier contains colorless compounds that hold anthocyanins in suspension, preventing them from precipitating out.

Viticulture

Northern Rhone Viticulture

Steep Slope Challenges

  • Unterraced vineyards require annual repositioning of stones that wash downhill
  • After harvest, vignerons strap buckets to their backs and cart "topsoil" back up
  • Most harvesting is manual — steep terraces impossible to machine harvest

Training Systems

Southern Rhone Viticulture

Gobelet Training

Most Southern Rhone vines are trained using the gobelet (bush vine) method. This ground-hugging system protects vines from the Mistral. Sturdy, upright canes like those of Grenache are ideal.

Harvesting

  • Vineyards can be machine or hand harvested
  • Trellised (Guyot) vines lend themselves to mechanical harvesting
  • Gobelet vines require hand harvest
  • Only Beaumes de Venise AOC mandates hand harvesting by law

Vine Spacing & Irrigation

  • Southern vines spaced more widely due to depleted soils and lack of water
  • Irrigation is not illegal but requires special permission
  • Groundwater levels dropping alarmingly

Winemaking

Northern Rhone Winemaking

White Wines

  • Most are still and dry
  • Small amount of sparkling in Saint-Peray (since 1825)
  • Typically fermented in neutral vessels; some aged in oak (rarely new)

Sweet Wines

  • Late-harvest Viognier in Condrieu is rare
  • Vin de Paille in Hermitage: Marsanne/Roussanne dried on straw mats for at least 45 days

Red Wines

  • Still and dry with vivacious acidity
  • Cornas and Hermitage most structured; Saint-Joseph and Cote Rotie more elegant
  • All except simplest wines are built to age

Aging Vessels

Beton (concrete) Inox (stainless steel) Demi-muids Foudres
It is neither typical nor traditional to age Rhone wines in small, new oak barrels — though some producers in Hermitage and Cote Rotie are doing so today.

Southern Rhone Winemaking

The Beauty of the Blend

Traditionally, Southern Rhone vineyards were planted with a mixture of different varieties. Although some vignerons still co-ferment, most now harvest and vinify each variety separately, then craft their blends.

White Wines

  • Most intended for consumption within 2-4 years
  • Fermented in neutral stainless steel or concrete
  • Some CdP whites aged in oak for greater texture and ageability

Rose Wines

  • Overwhelmingly dry and still
  • Methods: saignee, maceration, direct press

Cru AOCs
81%
Red (2019)

All vineyard area in the Northern Rhone is covered by one of eight appellations. Each is considered a cru, and all lie within the Cotes du Rhone zone of production. No Northern Rhone cru is authorized to make rose.

Right Bank (West) — Viognier's Home
Cote Rotie AOC 1940
Red Only
Right Bank

"Roasted slope" — named for the long hours of sunlight on its southeast-facing aspect. Highly-esteemed, steep slopes.

Red: Syrah [P] + up to 20% Viognier [S]

By law, up to 20% Viognier may be added to Cote Rotie reds, but in practice it typically constitutes 5% or less, if used at all. Viognier is co-planted, co-harvested, and co-fermented with Syrah. No white wine is produced.
Condrieu AOC 1940
Dry White, Sweet White
100% Viognier

Terraced vineyards on the right bank, most facing east. Medium- to full-bodied wines of moderate to low acidity. Sweet style (min 4.5%/45 g/l RS) was common in 18th-19th centuries but is rare today.

Chateau-Grillet AOC 1936
Dry White
8.6 ac / 3.5 ha — MONOPOLE

Located within the boundary of southern Condrieu. Wines aged 2+ years in oak barrels or tanks; can age 10+ years.

Chateau-Grillet is one of only TWO monopole appellations outside Burgundy (the other is Coulee de Serrant in the Loire Valley).
Right Bank (South) — 43 mi/70 km South of Condrieu
Saint-Joseph AOC 1956
Dry White, Red
37 mi / 60 km stretch

Long, narrow stretch with varying aspects. Matures more quickly than other Northern Rhone crus. Production: ~86% red, 14% white.

White: Marsanne Roussanne
Red: Syrah [P] + up to 10% Marsanne/Roussanne

Cornas AOC 1938
Red Only
100% Syrah

Steep, southeast-facing terraced slope of granite forming a natural amphitheater. Jean-Luc Colombo describes it as "an island of the south in the north."

Cornas is 100% Syrah with NO white grapes permitted (unlike other Northern Rhone reds). "Cornas" means "burned earth" in Celtic.
Saint-Peray AOC 1936
Dry White, Sparkling White
Marsanne, Roussanne

Most southerly Northern Rhone cru, but deep valley slopes make it slightly cooler. Traditional-method sparkling produced since 1825, though very little is made today.

Left Bank (East)
Hermitage AOC 1936
Dry White, Red, Vin de Paille
Left Bank

One of the oldest vineyards in France still under cultivation. Yields one of the longest-lived and most collected wines in the Rhone. Production: ~2/3 red, 1/3 white (both with similar aging potential). Up to 15% white grapes may be co-fermented with Syrah.

Hermitage Vin de Paille: Made by drying Marsanne and/or Roussanne grapes on straw mats for at least 45 days to concentrate sugars.
Crozes-Hermitage AOC 1937
Dry White, Red
Largest Northern Rhone Cru

Largest of the Northern Rhone crus with varied soils including sedimentary elements. Both reds and whites are lighter, faster-maturing versions of Hermitage. Up to 15% Marsanne/Roussanne may be co-fermented with Syrah.

Clairette de Die AOC 1942
Sparkling White, Sparkling Rose
96% of Diois

Two wines made under this appellation:

  • Clairette de Die: Traditional-method sparkling, 100% Clairette
  • Clairette de Die Methode Dioise Ancestrale: Sweet sparkling blend of Muscat and Clairette (Muscat dominates)
Most Clairette de Die production is Methode Dioise Ancestrale — a sweet sparkling wine dominated by Muscat, NOT the traditional-method 100% Clairette version.
Cremant de Die AOC 1993
Sparkling White
Traditional

Mostly Clairette with Aligote and small portion of Muscat a Petits Grains Blanc permitted.

Chatillon-en-Diois AOC 1975
Dry White, Rose, Red
Gamay [P]

Still wines in all three colors. Red and rose based on Gamay; white is a blend of Chardonnay and Aligote.

Southern Rhone Appellations

The Southern Rhone extends from Montelimar to Nimes. Unlike the north, vineyards stretch up to 50 mi/80 km away from the river.

Ventoux AOC 1973
White, Rose, Red
Largest "Other" AOC

Named after Mont Ventoux (6,273 ft/1,912 m), famous from the Tour de France. Mediterranean with Alpine influences — UNESCO Biosphere Reserve. Production: 36% rose, 50%+ red.

Luberon AOC 1988
White, Rose, Red
UNESCO Biosphere

More Provence than Rhone in profile — over 50% of production is rose. Mediterranean with strong continental influences.

Costieres de Nimes AOC 1986
White, Rose, Red
Extremely Hot

Summers regularly reach 95°F/35°C from June to August — some of the highest temperatures in France. Cold air from Petite Camargue cools nights.

Costieres de Nimes is unique in Southern Rhone: Syrah (not Grenache) is the dominant grape due to the extremely hot climate.
Clairette de Bellegarde AOC 1949
