Eau de Treignac: The Purest Water in France Nobody Has Heard Of

Eau de Treignac: The Purest Water in France Nobody Has Heard Of | Food Tour de France

Eau de Treignac — the extraordinary natural mineral water from a source above a village of 1,389 people in the Corrèze — is one of the most remarkable and most overlooked food products in this entire series. Today's Food Tour de France episode finishes in Ussel, deep in the heart of the Corrèze plateau, and tells the full story of a water that filters for fifteen years through granitic sand soil in the Millevaches regional nature park before emerging from its source at a constant temperature of 9.5 degrees Celsius with a dry residue of just 20 milligrams per litre — among the lowest mineral content of any naturally occurring water in Europe. For context, Evian has a dry residue of 309 milligrams per litre. Volvic sits at 130. Treignac at 20 is in a different category entirely. And it is now being poured at the Plaza Athénée in Paris, the Negresco in Nice and the Chabichou in Courchevel.

The episode tells the full story of how Eau de Treignac came to be bottled — from the family discussion led by Michelle Sainte-Laudy in 2002 that began the process, through the eight years of work required to move from idea to commercial production, to the 3,200-metre pipeline installed by the commune of Treignac connecting the source to the bottling plant at a cost of 130,000 euros. The commune of Treignac — population 1,389 — owns the source. The municipality receives a royalty per litre. And the water's extraordinary purity — a silica content that gives it a barely perceptible mineral dryness, a gentiane note that the head sommelier at Georges Blanc's three-star restaurant described as elegant, dry and mineral in the most delicate possible sense — has made it the water of choice for some of the finest tables in France. A water that does not interfere with the flavour of food. Which in the context of French gastronomy is exactly what is required.

The Food Tour de France is a daily series running alongside the 2026 Tour de France on Fabulously Delicious — one episode for every stage start and finish. The Treignac water episode connects directly to the Évian episode earlier in the series — two French mountain waters at opposite ends of the mineral content spectrum, both finding their audience in the finest restaurants in France through the same fundamental quality of not imposing themselves on the food alongside them.
