Arrouya noir is a red French wine grape variety grown in the Jurançon region of Southwest France.
The variety also shares some similarities in morphology with Cabernet Franc and until the late 19th century was often confused for the Loire and Bordeaux wine grape, especially in the Basses-Pyrénées and Hautes-Pyrénées region.
[1] Up until the late 19th century, plantings of Arrouya noir among vineyards in the foothills of the Pyrénées were misidentified as Cabernet Franc.
[1] Arrouya noir is a late-ripening grape variety that can be very vigorous and high yielding if not kept in check by winter pruning and late season green harvesting.
It's late-ripening nature means that it can be very sensitive to the conditions of a vintage and may not reach full physiological ripeness every year.
