An agreeable small wine town, Arbois is renowned for its excellent rosé wine, the rare and heady vin jaune, and the even more exclusive vin de paille wherein the practice of allowing the grapes to dry on beds of straw helped put Louis Pasteur on the trail of bacteria. Pasteur’s father moved his family to Arbois from Dole, and the scientist returned often to the creeper-clad Maison de Louis Pasteur, rue de Courcelles, now a museum.

The heart of town is place de la Liberté, lined with fine old houses and arcaded shops. One of the main local winemakers, Henri Marie, has an outpost here offering dégustations, and the S.I. has a list of other welcoming viniculteurs. The fine Romanesque Eglise de Saint-Just has a special winemaker’s window surrounded by a halo of golden-yellow glass the colour of vin jaune.
