Jean-Marc's winemaking is marked by meticulous attention to detail: careful adjustments like the selective choice of coopers and their wood, as well as blending wines from vines of varying ages, contribute to a range of superb wines. For his premier cru and other wines, Jean-Marc utilizes approximately 15% new barrels, whereas the grand crus receive 30% new Alliers oak. The resulting wines are typically highly concentrated and available in limited quantities, striking a balance between the robust flavors of older vines and the vibrant qualities of younger wines, ensuring richness and strength without being overwhelming.
