In 1971, Jacques and Geneviève Guillerault created Domaine des Caves du Prieuré in an ancient (18th century) winery located in the village of Crézancy. Since 1995, their son Gilles has presided over the 19 hectare estate, joined by his brother-in-law Sébastien Fargette in 2001. At Guillerault – Fargette, their holdings are planted 75% to Sauvignon Blanc with the remainder planted to Pinot Noir. From a plot of Sauvignon Blanc vines comes the cuvée “Iota”. The name comes from the Greek letter “ι” and impersonates the mouthfeel after drinking the wine. After manual harvest, the wine is fermented in stainless steel vats and aged for 18 month on fermentation lees. The plot of vines, from which the “Epsilon” cuvée comes, were planted in 1972, on Kimmeridgian marl soils. This land represents a small part of the estate, which is why the term “ε”, which is used to designate small numbers, is being used to name this cuvée. The cuvée “Psi” is made from pinot noir grapes from different plots found in the villages of Reigny, Bué and Sancerre. Here the Greek letter Ψ is used, which with its three lines, represents the balance between fruit, freshness and finesse.

Gilles Guillerault and Sébastien Fargette are commited to sustainable viticulture. Natural grasses are grown between the rows and the soils are worked manually. No herbicides or pesticides are used. Each year, the harvest is brought in and carefully sorted on their sorting table before being pressed. The juice is allowed to settle by gravity before fermentation.
