France's palest red comes from one of its smallest great regions. Poulsard — thin-skinned, quick to fade — gives a wine so translucent it is routinely mistaken for rosé, and forgotten by nobody who understands it: redcurrant, rose hip, a smoky whisper, served cool. Arbois has history to match the colour: the decree of May 1936 made it France's first AOC.
This is also Pasteur's town. He grew up in Arbois, kept a vineyard nearby, and used its wines in the experiments that founded modern microbiology — fermentation and spoilage explained from a Jura cellar. The grape he knew still rules the local reds, unfashionably pale through every era that demanded darkness, and now prized for exactly that.
