This is a wine from The Jura region of France. Traditionally they may be aged oxidatively and be somewhat funky. It is an intentional style not a wine flaw.
100% Chardonnay. A brilliant old-vines Chardonnay grown in clay/limestone soils. Very low yields. The wine is raised in demi-muids without any intervention and without and addition of SO2, for around 2 years. During this time the casks are topped off (ouillé) to avoid oxidation. Bottled without fining or filtering. 14% alcohol.
