Former head winemaker of Jean-Marc Morey in Chassagne-Montrachet, Jean-François Gavenat has become one of the most talented winemakers in the Jura since he took over his family domain in 1998. His vineyard spans 13 hectares and includes many different grape varieties. Gavenat has a natural and biodynamic approach (without certification) and produces some single vineyard wines (the domain boasts 50 different cuvées). The vines are relatively old and meticulously cared for. The yields are low and the vinifcations gentle. Some of the reds are matured in amphorae are of a very high quality ; Gavenat has recently got involved in negociant activity. This domain has played an important part in increasing the popularity of wines from the Jura. Production is small and the wines are prized by wine lovers all over.

Les Chalasses Marnes Bleues is produced from the Savagnin Vert grape and matured in demi-muid barrels, and is ullaged (not oxidised). The result is a wine of great freshness, with mango and pineapple aromas enhanced with chalky notes. The palate is a perfect balance between richness and tautness, with impressive length.
