Science Festival with Professor Yves Coppens

Published on

Oenology and geology are linked because the soil type is crucial to determine the wines’ quality, depth and complexity. Sancerrois’ soils are of Jurassic origin: clay-limestone, argilo-siliceous or mainly limestone. During Jurassic period, which extends over 70 million years (from 205 to 135MYA), Sancerre was located in the middle of the seas. The bedrock formed during the Jurassic era is an ideal soil for the vine.

That’s why we follow the Association of Geologists of Sancerrois with whom the Bourgeois Family has set up a partnership, which organizes The Science Festival on October 4th and 5th, 2019, an event that you do not want to miss out on.

This event will be marked by the opening preview of The House of Geology. The House of Geology is sponsored by the famous paleontologist Yves Coppens who discovered the Australopithecus Lucy in 1974.  On this occasion, several scientists including Professor Yves Coppens will lead conferences.

The House of Geology is located in the old quarry that are the caves de la Mignonne in Sancerre, formed during the Oxfordian period which was dated during the Jurassic era. It will offer an immersive tour through Augmented Reality to immerse the visitor in the sea from 160 million years ago in the heart of the dinosaur era. In the same way, strange fossils, tools carved by the first men, reconstructions of different periods of life’s evolution and many other treasures will also be unveiled to the public.
