Domaine Gerard Fiou is a small family domaine in the east of the Sancerre appellation in the town of Saint Satur. There are only a handful of producers here and the soil is unique in that it has a high percentage of silex (or flint) which typically is identified with Pouilly Fumé, which lies just across the Loire river. The domaine now has just under 10 hectares, and they are in the process of converting to certified organic viticulture. Only 15% of the Sancerre appellation has these special silex soils. The terroir, coupled with the older vineyards (an average of 60 years old), gives the wines have a unique and intense mineral expression that is distinctly Sancerre. Domaine Gerard Fiou has been certified organic as of the 2023 vintage.
