This is a wonderful quaffing wine in the heat of summer, with fresh, fruity notes. Labbé’s white Jacquère is as good (with less Alc) than a vast majority of Sancerres and tastes similarly and replaces them at a fraction of the Sancerre price.
The grape they grow is Jacquère. (The Abymes made by Labbé is 100% Jacquère, but the appellation tolerates 10% of other grape varieties). The soil is argilo/calcaire with some 2 inch stones which were left as debris of an avalanche from the Alps.
They de-bud in the spring to limit the yields. This is something that no-one does at this price level (too labour intensive).They let grass grow in the rows between the vines to force the roots to go deeper for nourishment and soak up the terroir tastes of the subsoil. Vinification practices preserve both varietal typicity and freshness - the cellar temperature is controlled, and fermentation occurs through indigenous yeasts in non-reactive tanks/foudres.
