What is "barbaroux"

Barbaroux (also known as Grec rouge) is a pink-skinned French wine grape variety grown in south eastern France. It is a permitted variety in the appellation d'origine contrôlée wine of Cassis in Provence as well as in the Ajaccio region of Corsica. While it is sometimes known under the synonym "Barbarossa", DNA profiling has shown the Barbaroux grown in Provence is distinct from the Barbarossa vines grown in Liguria and Piedmont and is likely unrelated to all Italian Barbaross vines. There is also debate among ampelographers about whether the Barbaroux vines in Provence and Corsica are the same grape or separate Vitis vinifera varieties.
