In the Heart of Grande Dixence-The Titans

The Titans is the name given to the men who worked on the construction of the gigantic Alpine dams. The Grande Dixence dam is one of the superlatives: the highest gravity dam in the world and the most massive in Europe. Les Titans is also the range of wines created in 2005 by Luc Sermier, oenologist at Provins, as a tribute to these formidable men.


Les Titans wines mature under extreme conditions inside a dam wall in the Swiss high mountains.

The constant low temperatures, the altitude, the low air pressure, and the high humidity make up the technical characteristics of these unique wine cellars. The ageing of the wine slows down, which gives it additional elegance, more expression, and freshness. It also benefits from an amazing storage potential.
