Biodynamic. Together with its sister-in-arms Cuvée Edmond, Dix-Neuf is the antithesis of modern, ‘textbook’ Sancerre. This jaw-dropping Sancerre is drawn from the oldest vines in the Moussière vineyard (approximately 100 years of age), cropped at Grand Cru Burgundy-level yields (in fact the lower end of this range). The wine was fermented and raised in 2,000-litre, tronconique wooden tanks for 12 months before a spell in steel on lees. Only 500 cases per year get to see the light of day.
