Arbois AOCannual, the first Sunday of September, falling with the feast of Saint Just, patron of the parish; the 2026 edition ran 5 and 6 September1 day
A harvest offering documented at Arbois since 1665. White and black grapes are fixed in alternating bands on a straw frame to make one large bunch, which is carried through the town and presented in the church.
Pours: Arbois whites, Trousseau, Poulsard, Vin jaune
Tip: Admission is free. Since 1922 a grape crown has been built alongside the Biou itself, and the whole thing is the file France has put to UNESCO for the intangible heritage list, with the committee sitting late in 2026.
Arbois AOCannual, on a Sunday in late September; the 2026 edition started at 10h on 27 September1 day
Vadans is one of the twelve Arbois communes and keeps its own Biou, a procession built round the same grape offering as Arbois but on a village scale, with the bunch carried from the Place de la Liberte.
Pours: Arbois whites, Trousseau, Poulsard
Tip: No date rule is published for this one, so check the commune listing rather than assuming the Arbois Sunday. It usually falls three weeks after Arbois, which makes a two-Biou September trip possible.
Polignyannual, around Saint Michael's day on 29 September; the 2026 edition was listed for 4 October1 day
Instituted in 1901 by an Arbois grower who had settled in Montholier. Two moulds shape the bunch, four men carry it to the church, and it stays on show for a week or more before the grapes are given away.
Pours: Cotes du Jura whites, Cotes du Jura reds
Tip: Montholier worked close to 100 hectares of vine in 1870 and has almost none left, so this is a procession kept up by a village that no longer really grows wine. The team running it has said openly that it needs younger members.
