Harvested from the Domaine du Mas Blancs oldest Grenache vines, the Banyuls Collection 1978 is a special subset of its Banyuls Vieilles Vignes. Hand-harvested and trodden by foot, it was fermented in cement tank with native yeasts and aged in 650-liter oak demi-muids for 10 years. A single 225-liter barrel was then diverted from bottling and set aside for continued elevage as part of the estates library of its most important wines. Dubbed Collection, only three vintages have been previously released to the public.
