2018 PerSe, Inseparable, Gualtallary, Mendoza, Argentina

Known as Auxerrois in Cahors, Cot in the Loire and Malbeck in Argentina, this grape has undergone a mini renaissance in the last decade, largely fuelled by its success in South America. It used to be a staple component of the Bordeaux Blend, but it never recovered fully from the 1956 frosts and its plantings there have fallen by 75% as growers have replaced it with more fashionable, and crucially, more durable grapes.
