It’s from old vines (up to 70 years), organically farmed and planted entirely in terres blanches (or the famous Kimmerigian limestone also found in Chablis) soils - the source of Sancerre’s purest, most quintessential and longest lasting wines. As one commentator explains:
Kimmeridgian Limestone imbues wines with exceptional density and structure, as well as the ability to age for decades.
It's frankly amazing that the soil is filled with fossilized oysters and other marine life, and that there's often a flavor in these wines that reminds us of the sea.
Sancerre from Kimmerigian sites) tend to be the longest-lived wines from the region and among the longest- lived Sauvignon Blancs in the world.
We’ve had a lot of great Sancerres lately, but aside from the amazing 2018 Grand Chemarin from Jean-Max Roger (2 cases left, at $44.99), this is the richest, purest, finest and most delicious I can remember. And a steal at $29.99.
