D Theory

« Let us observe our natural environment every day and we will be able to better
understand it. Because what may work here will not necessarily work elsewhere. »

Being written in the genetics of our elders, this ability to embrace change is today fully
integrated into our DNA. And it is to honor this tailored approach – applied to Crouttes-sur-
Marne by each of our wise experimenters – that we claim our D theory signature.

D as the strong marker of the flagship letter of our double surname: Dérot-Duligny. You might
see a parallel with another famous scientist, who became known for his theory of Evolution.
We too, in our own way, have developed a natural ability to adapt to our environment. That
of the panoramic terroir of the Western Marne Valley.
