The most recent official Premier Cru list was established in 1986. It names 79 vineyards covering a total surface area of about 600 hectares. Chablis winegrowers decided to reclassify these plots in order to promote only 17 of them. The vineyards in question are located on both sides of the Serein River in the communes of Chablis, Fontenay, Maligny, Chichée, La Chapelle-Vaupelteigne, Courgis, Fleys and Beines.
The 37 hectares of the Montmains climat are located on the left bank of the Serein in the commune of Chablis. Often austere when young, and marked by mineral and lemony aromas, these wines stand out for their excellent ageing potential. Gentle slopes. Kimmeridgian marl.
