Our land and its microclimate


Sauternais'area is located on the left bank of the Garonne, at 40 km upstream from Bordeaux.

This area is composed of 5 villages:

o       Sauternes, Preignac, Bommes, Fargues, all located on the right bank of Ciron. (tributary of Garonne) 

o       Barsac located on the left bank of Ciron.

Barsac, old Royal provostship, benefits from the double appellation Sauternes and Barsac.




The miracle of Sauternais

Barsac appellation benefits from a specific microclimate due to the confluence of cold waters from Ciron and those, warmer, of Garonne; this develops in autumn morning mists which let quickly place to the sun. This climatic alternation helps the development of noble rot (Botrytis Cinerea).


It is endowed with soil made  up of various strata of silica, chalk and gravel forming an harmonious entity. These strata , deposited with the passing of time, enable the wine to acquire its finess, strength and lusciousness.
