Bourgeois's 2019 Sancerre Blanc d'Antan Terroir de Silex is from a vineyard first planted in 1936 on predominantly flinty soils. The nose is intense, fresh and pure in all its flintiness and dried herbal aromas. This is a really pure and mineral Sancerre, or life from stone (to quote a well-known South African Sauvignon). On the palate, this is a pure, fresh and saline, quite firm and grippy Sancerre with still a little astringent tannins but lots of purity and tension. This is definitely a wine for connoisseurs and patient wine lovers. If you like oysters, you'll like this wine too. 14% stated alcohol. Natural cork. Tasted in March 2022.
