Natural winemaking at Domaine Vacheron is second nature. Taking care of the soil, and in turn the vine, is of the utmost importance to the family. Vines have been cared for biodynamically since the early 2000s, and the estate is certified in both organic and biodynamic practices. No synthetic materials whatsoever are used in the vineyards; the family makes its own organic compost. Yields are naturally low.

Harvest is exclusively by hand. Grapes are fermented on indigenous yeasts in a combination of stainless-steel or cement tanks and wooden, open-top fermenters. Wines are aged either in large oak cask or French oak barrels, depending on the cru and the vintage, and are bottled unfiltered, according to the lunar cycle.

Sourced from hillside vineyards around the town of Sancerre, with a mix of chalk and flint (silex) soils. About 20% of the blend is wine from a selection of single-vineyard plots, which gives more complexity (also some wood influence, as the domaine’s single-vineyard Sancerre Blanc wines are aged in larger wooden casks).
