The Jura counterpart to Pineau des Charentes and Floc de Gascogne, Macvin du Jura is a vin de liqueur, a sweet and powerful blend of two-thirds grape juice and one-third Marc du Jura (pomace brandy) that is aged up to 30 months in casks. Macvin comes in white, pink and red varieties (usually the first) and, despite having been around since at least the 14th century, was granted its own AOC only in 1991. Locals serve it chilled as an aperitif, with desserts or after dinner mixed with marc (usually one part Macvin to two parts marc).

Macvin du Jura, Jean Bourdy ($47.00, 3 btls/case, La QV)
A rare rosé Macvin. Strawberry, fruit cake and dried spice (caraway, clove, cinnamon). Sweetness balanced by acidity and spice. Lingers long. Excellent. (Buy again? Yes.)

Macvin Rouge, Pinot Noir, André et Mireille Tissot ($39.25, 6 btls/case, Les Vins Alain Bélanger)
Deep red. Candied cherry on steroids, spice and an undernote of dried blood. Dense, fruity sweetness lifted by acid and alcohol. Marathon finish. Fascinating. (Buy again? Yes.)

Stéphane Tissot suggests chocolate as a pairing for his red Macvin. At the tastings, it was successfully served with squares of Valrhona Guanaja bittersweet chocolate. Further research conducted a few days later found it an unbeatable match with a selection of exquisite chocolate, hazlenut, pistachio and raspberry pastries from Olivier Potier.
