Excellent Chablis is from 10–30- year-old vines grown on Kimmeridgean marl. This terrain is formed from exoguira virgula (fossilised oyster shells) and the specific gout-à-terroir is said to derive from this.

Gérard Tremblay and his wife, Hélène, oversee a domain that they inherited in a line of five generations, but which they have mostly built themselves. With 80 acres of vines under production, most of them in the best Premier Cru and Grand Cru appellations, their list of Chablis is among the most prestigious in the region. Tremblay is known locally as an accomplished wine maker. He is justly famous for his ability to draw out the typicity of distinct appellations, underlining the terroir of his vines vintage after vintage.
