The Cassis Appellation d’Origine Contrôlée (AOC) was the first French wine region to receive the AOC seal when the Institut National de l’Origine et de la Qualité (INAO) was established on 15 May 1936.
Archaeologists have traced Cassis’s viticultural roots back to the Greeks of Phocaea, who founded the settlement in 600 BC and planted the first vines on the banks of what is now the Bay of Cassis. The ancient Greeks introduced the Ugni Blanc grape variety, which still grows in the limestone soils of the Calanques today.
Centuries later, Roman merchants expanded the vineyards and shipped their wine in amphorae, some of which have been recovered from the seabed near the cliffs. ‘These amphorae are a tangible reminder that Cassis was already an important wine export hub in the first centuries of the Common Era,’ says Dr Hélène Bouchard, a historian at the University of Provence. ‘The continuity of viticulture here is extraordinary.’
Written evidence of the vineyards re-emerges in the Middle Ages. A notarised deed from 1381 mentions a plot of land called ‘L’Arène’ – a small area of land by the sea dedicated to growing vines. Over the next two centuries, the vines gradually crept up the slopes, harnessing the Mediterranean breezes and the thin, mineral-rich limestone soil.
A white wine revolution in the sixteenth century
While the surrounding regions of Provence were dominated by robust red wines, Cassis took a different path. By the sixteenth century, local growers had deliberately specialised in white wines, a strategic decision that would later come to define the area’s identity. The microclimate of the Calanques, salty sea air, intense sunlight and cool sea breezes, is tailor-made for white grapes.
Phylloxera, Resurrection and the Birth of the AOC
The 19^(th)-century phylloxera epidemic devastated vineyards across Europe, and Cassis was no exception. The tiny insect-borne pest annihilated the vines, leaving the hillsides barren. However, a handful of resolute growers refused to surrender. They grafted new vines onto American rootstock, which proved resistant to the pest, and simultaneously shifted the region’s focus to dry, crisp white wines.
Their perseverance paid off in 1936, when the French government officially recognised the unique character of Cassis wines by granting them the first AOC status, newly equipped with the INAO.

Numbers that speak
Today, the Cassis AOC covers 215 hectares (approximately 530 acres) and produces an average of 7,500 hectolitres (equivalent to approximately one million bottles) per year. The appellation’s regulations, last revised in 1996, stipulate that at least 60% of any vineyard’s planting must be a blend of the two flagship varieties, Marsanne and Clairette.
Marsanne, originally from the northern Rhône, thrives on the salty coastal breezes, delivering delicate white floral aromas and an ageing profile that evolves towards honeyed nuances.
Clairette, a native of Provence, flourishes on arid limestone soils, imparting fresh acidity and notes of aniseed, acacia honey and garrigue herbs, which perfume the surrounding hillsides.
The resulting blend is unmistakably Cassis: 67% of the appellation’s output is white wine, 30% rosé and a modest 3% red.
Terraced Vines, Cliffs, and the Calanques Protection
The vines of Cassis form a visual symphony of stone walls and narrow ‘restanques’ (terraced plots) against the backdrop of the deep blue Mediterranean. The vineyards form a horseshoe-shaped amphitheatre, bounded to the west by the rugged Calanque mountain range and to the east by Cap Canaille, the highest coastal cliff in France, soaring 400 metres above sea level.
In 2012, the entire AOC was incorporated into the Calanques National Park, making Cassis the only French wine region completely surrounded by a protected natural area. While this status imposes strict environmental controls, winemakers view it as an opportunity rather than a constraint.
‘We are the stewards of a landscape that is both cultural and ecological heritage,’ says Elise Rivière, the second-generation owner of Château des Calanques. ‘The national park designation forces us to adopt practices that safeguard biodiversity, from limiting pesticide use to preserving the wild herbaceous flora that contributes to our wine’s aromatic signature.’
A New Green Chapter
Over the past two decades, the planted area has increased from 180 to 215 hectares, driven by younger vintners who are keen to embrace modernisation while respecting tradition. Investments in temperature-controlled fermentation tanks, solar-powered winery facilities and precise canopy management techniques have improved quality and sustainability.
An increasing number of estates have adopted organic and biodynamic certification. According to the Syndicat, as of 2025, 62% of vineyards are cultivated without synthetic chemicals and 15% have achieved full organic status.

Challenges on the Horizon
Despite the optimistic outlook, the vineyards are under increasing pressure. Coastal urbanisation, rising sea levels and the ever-increasing heat in southern France are threatening the delicate balance that has been maintained for millennia.
The Mediterranean is warming faster than any other sea. By 2050, average summer temperatures in the Cassis basin could rise by 2–3°C, affecting grape phenology and acidity.
In response, local winemakers are experimenting with planting at higher altitudes and exploring heat-tolerant clones of Marsanne and Clairette. Some, such as Domaine de la Pointe, are trialling modest proportions of Sauvignon Blanc and Alvarinho, varieties that could preserve freshness under warmer conditions.
Cassis, the birthplace of the French AOC, is not resting on its laurels. It is weaving its ancient legacy into a sustainable future, all the while keeping the Mediterranean’s salty breeze, the limestone’s mineral kiss, and the wild herbs of the garrigue at the heart of every bottle.
