Today, the winemaker François Chidaine is a leading name in Montlouis, having ushered in a new generation of talented wine-makers. In 1984, he began to work as an employee at his family's winemaking estate in Montlouis. In 1989, he set up on his own with 3 hectares of the family estate and 1.5 hectares that he purchased himself. He quickly adopted organic farming practices and began converting his entire domain to this approach in 1992, while continuing to expand (10 hectares in Montlouis in 1998). The following year, his Spanish-born wife Manuéla joined the estate, which was then converted to biodynamic practices.A new page was turned in 2002 with the leasing of vines from Prince Poniatowski's Clos Baudoin estate, which he then purchased in 2006. He was joined by his cousin Nicolas Martin, with whom the Chidaines formed a GAEC (a jointly-run agricultural partnership). Today, the estate spans 45 hectares: 22 in Montlouis-sur-Loire and 10 in Vouvray, where Chenin is the sole grape variety grown. A further 13 hectares in Touraine showcase Sauvignon, Pinot Noir, Grolleau, Cabernet Franc, Côt, and Pineau d’Aunis. In total, over 50 plots of vines are elevated to their purest expression by the estate.
François Chidaine is also the chairman of his appellation's trade union. As well as its exemplary use of biodynamics in working its vines, the estate also aims to highlight its various different soil types by producing a number of cuvées based on the specific characteristics of each vineyard. François Chidaine is obsessively rigorous in his approach to vineyard work – a characteristic he shares with Manuéla and Nicolas Martin and their entire team (numbering nearly a dozen full-time employees), whose common goal of excellence has formed them into a very closely-knit unit.François Chidaine also heads up the growers' union for the Montlouis appellation, and (along with Jacky Blot) remains a textbook example of a producer who has inspired a whole new generation of talented young winemakers from the appellation.

Les Argiles is a wine made from the Chenin Blanc grape variety. The vineyard is ploughed and nematicides and melliferous plants are sown in the rows. The only preparation used comes from animal, plant and mineral matter. The soil consists of clays and white chalk. The wine is exclusively fermented by native yeast, in demi-muids (wood, 600 litres). There is no malolactic fermentation. The resulting wine has a clear and luminous hue, with hints of lemon and white fruit on the palate and nose. Nice balance, tense and saline finish.
