Summary

Plaimont is not a classic wine estate but a collective: the growers' cooperative based in Saint-Mont in the Gers department pools the vineyards of around 800 to 1,000 family holdings across Gascony and the foothills of the Pyrenees. With roughly 5,300 hectares it is by far the largest wine producer in South-West France. What is remarkable, though, is not the volume but the attitude: Plaimont effectively built the Saint-Mont appellation from scratch, has fought for decades to preserve almost vanished local grape varieties, and looks after one of Europe's oldest vineyard monuments with the pre-phylloxera vines of Sarragachies.

History

Plaimont's story begins in 1979 – and it begins out of an emergency. Back then Gascony was above all a supplier to the Armagnac distilleries; falling demand for brandy threatened to drag the region's viticulture down with it. Grower and cooperative manager André Dubosc persuaded the three cellars of Plaisance, Aignan and Saint-Mont to join forces. The first syllables of their names produced the coined word PL-AI-MONT.

The merger gave the small holdings market power, technical equipment and, above all, an idea: to stop delivering anonymous bulk wine and instead produce distinctive bottled wines with a clear sense of origin. The greatest success of that strategy is the recognition of Saint-Mont as an appellation in its own right, which Plaimont prepared and accompanied over decades. In 1999 the group grew further as the cooperatives of Crouseilles and Condom joined. Since 2012 Olivier Bourdet-Pees has been at the helm, a trained oenologist who had previously been the house's technical director from 2008.

Location & Terroir

The catchment area lies in the Piémont Pyrénéen, the hilly foreland of the Pyrenees between the Adour and the Armagnac country. The vineyards are spread across the departments of Gers, Landes and Pyrénées-Atlantiques – a landscape of gentle ridges, farmsteads and maize fields that has remained largely untouched by mass tourism.

Two climatic influences meet here: mild, damp Atlantic air from the west and the warm, dry foehn wind that sweeps over the Pyrenees. The result is long, sunny autumns that allow late-harvested white grapes to ripen fully without losing acidity. The soils are strikingly varied: iron-rich gravel and sand on the terraces, clay-limestone slopes in the Madiran and Pacherenc du Vic-Bilh areas. It is precisely the sandy soils that explain why individual parcels survived phylloxera in the 19th century.

Style & Philosophy

The red heart of the cooperative is Tannat, a variety with exceptionally high tannin and dark fruit. Plaimont has done much to make the once almost rustic Madiran more approachable – through careful selection, adapted extraction and ageing in wood. In Saint-Mont, Tannat is traditionally blended with Pinenc (the local name for Fer Servadou) as well as Cabernet Sauvignon and Cabernet Franc, which gives the wines spice, freshness and a finer texture.

The whites show the other face of Gascony: Gros Manseng, Petit Manseng, Petit Courbu and Arrufiac produce spicy, citrus- and exotic-fruit-driven wines in Saint-Mont and Pacherenc du Vic-Bilh – dry or, from late-harvested Petit Manseng, lusciously sweet. Colombard and Ugni Blanc give the crisp, affordable everyday whites of the Côtes de Gascogne IGP for which the region is internationally known.

The research work is defining: since 2002 Plaimont has maintained an ampelographic conservatory in which old, almost vanished local varieties are collected, identified and propagated. Some of them can now be found in wines again – an approach that attracts attention far beyond the region in the face of climate change.

Notable Sites & Wines

The most famous is the tiny parcel at Sarragachies: a never-replanted, ungrafted vineyard whose vines date from before the phylloxera catastrophe and which in 2012 became the first vineyard parcel in France to be listed as a Monument historique. Alongside Tannat and Pinenc it contains varieties that no longer exist anywhere else.

From it and from another old parcel near Saint-Mont comes the rarity Vignes Préphylloxériques, of which only a few numbered bottles are filled each year. Beside it stand the house's well-known ranges: dense Madiran reds, the Saint-Mont cuvées in red and white, the dry and sweet Pacherenc du Vic-Bilh, and the fresh whites of the Côtes de Gascogne.

Awards

In the international trade press, Plaimont is regarded as a model of how a cooperative can take quality and origin seriously, and it is regularly distinguished in wine guides and competitions. Its work on ampelographic heritage earns particular recognition: the listing of the Sarragachies vines as a historic monument and the revival of lost varieties have given Plaimont a reputation as a guardian of the genetic heritage of the French South-West.

Frequently asked questions

What exactly is Plaimont?

Plaimont is a growers' cooperative based in Saint-Mont in the Gers department, in the heart of Gascony. Around 800 to 1,000 member growers bring in their grapes from roughly 5,300 hectares. That makes Plaimont by far the largest wine producer in South-West France – and at the same time the driving force behind the Saint-Mont appellation.

What kind of wines does Plaimont make?

The range runs from powerful, tannic reds made from Tannat and Pinenc in Saint-Mont and Madiran, through dry and sweet white wines from Pacherenc du Vic-Bilh, to fresh, variety-driven everyday whites from the Côtes de Gascogne IGP made of Colombard, Ugni Blanc and Gros Manseng.

Why are Plaimont's old vines so famous?

Since 2002 Plaimont has run an ampelographic conservatory in which almost forgotten local grape varieties are secured and propagated. Best known is the ancient parcel at Sarragachies, never destroyed by phylloxera, which in 2012 became the first vineyard in France to be added to the list of Monuments historiques.

Is Plaimont a good introduction to South-West France?

Yes. Because Plaimont covers almost every style of the region and prices sit mostly in the affordable to mid range, a handful of bottles is enough to explore the full breadth of Gascony – from a light Colombard to a dense, long-lived Madiran.
