The spring
never stopped.
A living drink from the historic Prosper spring of Ginoles-les-Bains.
The spring at Ginoles-les-Bains has run for over a century, sixteen litres a second, at a steady 23°C long after the resort around it fell silent. Prosper is what happens when you bring it back: old water, a living ferment, new life.

THE STORY
SOURCE · DISCIPLINE · REVIVAL
The spring never stopped.
In 1871, a civil engineer named Prosper Lassave bought a quiet valley two kilometres from Quillan and built a thermal resort around its water. For sixty years it was one of the most fashionable destinations in the south of France — a thousand guests a season, marble baths, a grand hotel, André Gide walking the park.

Then the world moved on. The baths closed in 1958. The estate passed through other hands — a swimming club, a workers' holiday camp, a discotheque in the old mill — and slowly fell silent. Roofs collapsed. The park went wild.

But the spring kept flowing. Sixteen litres a second, a steady 23°C, running through the channels of an empty estate for decades with no one left to drink it. It never stopped. It was just waiting.

Prosper is what it was waiting for. We didn't invent anything here. We did what fermentation does: take something the world had written off, introduce a living culture, and let it come back more alive than before. Old water. Living ferment. New life. That is the entire idea, and it fits in a bottle.
Prosper is what happens when the slowness of a mountain village meets the appetite of a city. The spring was never the property of one town, and revival doesn't stay put. Every time you raise it, you're toasting a revival that actually happened - and the next one.
Drink to Prosper.
