Francois Cotat is in Chavignol, in the Sancerre region of France’s Loire Valley. The domaine was until about 20 years ago part of a larger domaine owned by the brothers Francois and Paul, but they retired and passed it on to their sons, who now bottle under their own names. The younger Francois makes wines in what the French call the biodynamic, or natural method, meaning the grapes are grown organically and tended and harvested by hand. Additional sugar, yeasts and sulfur dioxide are avoided during harvest. Cotat is also known for harvesting later than most of his neighbors. The domaine’s slopes are steep and chalky, which adds minerality to his cuvees.
