In accordance with biodynamic principles, all fruit is hand harvested from vines up to forty years of age. A patented Mistral® apparatus removes the leaf material and infertile berries from the vineyard, providing cleaner bunches. A luxurious cepage of Cabernet Sauvignon and Franc, Malbec, Merlot and Petit Verdot, the grapes are carefully sorted before fermentation to indigenous yeasts and malolactic bacteria. No acid or cultured yeasts are added, achieving a wine with a sense of place through a completely natural process. Components are separately vinified before being treated to nineteen months maturation in a selection of new and seasoned French oak barriques.
