Tibouren or Rossese di Dolceacqua is a red French wine grape variety that is primarily grown in Provence and Liguria but originated in Greece and possibly even the Middle East. Intensely aromatic, with an earthy bouquet that wine expert Jancis Robinson describes as garrigue, Tibouren is often used in the production of rosés.
While the unique aroma and character of the wines produced by Tibouren are valued by producers, it is not a widely planted variety. This is due, in part, to the viticultural issues of the grape's sensitivity to coulure and tendency to produce highly irregular yields from vintage to vintage. The wines produced from Rossese are a local specialty found around Dolceacqua.
While Tibouren today is almost exclusively associated with the Provence wine region, French ampelographer Pierre Galet suspects that the grape probably has Greek origins or possibly Middle Eastern. Galet's theory derives from the uniquely shaped leaves of the Tibouren vine, which include deeply incised lobes that are usually seen in Vitis families of the Middle East. He speculates that over the evolution of the grape its ancestor vines were brought to Greece and from there it was probably introduced to France by the Ancient Greeks at their settlement in Marseilles.
