I stumbled upon a bottle of Legrand-Latour Eocene in a shop in Reims after an employee from Laherte Freres said this was one of his current favorite Champagnes. My husband and I drank it over the span of a day in and out of our hotel, and were blown away by it's incredibly mineral and savory style! The type of wine you just wanted to keep coming back to. We came home to find out is now being imported to the U.S. and were excited to continue exploring this domaine! Legrand-Latour is a very geologically focused estate that in 2004 began digging to search for fossilized shells. They ended up doing an excavation of a mile long, 300 meter deep hand carved cave to help document and preserve sea creatures from 45 million years ago, this is now open as a museum. 
From a winemaking standpoint the family had always sold to the co-op until their son returned to the vineyards, and began changing the conventional farming practices to organic, and after 5 years in 2017 he decided to quit the co-op and bottle his own wines. The names of each wine come from the different geological strata since he believes that geology plays the biggest role in determining the wines identity. Today we have three different cuvees to offer from them, Eocene, Ypresien, and Lutetien.
