2015 Sancerre, Caillottes, Domaine François Cotat, Loire

An important white grape in Bordeaux and the Loire Valley that has now found fame in New Zealand and now Chile. It thrives on the gravelly soils of Bordeaux and is blended with Sémillon to produce fresh, dry, crisp  Bordeaux Blancs, as well as more prestigious Cru Classé White Graves. It is also blended with Sémillon, though in lower proportions, to produce the great sweet wines of Sauternes. It performs well in the Loire Valley and particularly on the well-drained chalky soils found in Sancerre and Pouilly-Fumé, where it produces bone dry, highly aromatic, racy wines, with grassy and sometimes smoky, gunflint-like nuances.

Francois Cotat produces idiosyncratic, complex and ageworthy Sancerres from his tiny 3 hectare estate at the heart of the prized Chavignol commune which lies on Kimmeridgian clay and Caillotte soils. Such is the steepness of the slopes (in the vineyards of Les Monts Damnés, Le Cul de Beaujeu and La Grande Côte) that cultivation is arduous and must be done entirely by hand. The grapes are late-picked for maximum flavour and in the winery, François adopts a very traditional, non-interventionist approach, barrel-fermenting the juice in old demi-muids using natural yeasts. At times, François' wines have had to be declassified to "simple" Vin de Table status due to a higher level of residual sugar or alcohol than the appellation's rules permit or simply because the local committee find them too atypical. François racks according to the phases of the moon and the wines develop with age and, in the best vintages, can be cellared for more than 50 years.
