100% Pineau d'Aunis. Pineau d'Aunis is an historical black grape of the Touraine--in the same family with Menu Pineau and its more sophisticated cousin Pineau de la Loire, aka Chenin Blanc--but is a rare bird even here in its native Loire. The Puzelats source tiny quantities of it, mainly from neighbor vigneronne Valérie Forgues, who organically tends and hand harvests her hundred-plus-year-old vines. 2015 was their first vintage of this bottling. Typical of Tue-Boeuf reds, the fruit goes as whole clusters into huge oak vats for a spontaneous fermentation, which is a semi-carbonic maceration with a closed top for around 10 to 14 days. The clusters are pressed and the wine finishes with a non-carbonic, open top fermentation in vat. The Pineau is aged for about 8 months in used Burgundy barrels; it is bottled without fining or filtration and with little to no sulfur. It is classified as Vin de France.
