Two ancient Lebanese white grape varieties — Merwah and Obaideh — are among the most historically significant and scientifically interesting in the Middle Eastern viticultural zone:
Merwah (Arabic: مروة): a white variety with documented cultivation in the Mount Lebanon area for at least several centuries. DNA profiling by Lacombe et al. (2007, published in Theoretical and Applied Genetics) established that Merwah is genetically very close to the French variety Chardonnay — close enough that the relationship may be parent-offspring or the sharing of a common recent ancestor. The implication is significant: Chardonnay (the world's most planted white wine grape) may have a Lebanese ancestor, or Merwah and Chardonnay may share parentage through an ancient variety that no longer exists in pure form.
Obaideh (Arabic: عبيدة): similarly ancient, grown alongside Merwah on the terraced limestone slopes of Mount Lebanon. DNA analysis has identified Obaideh's genetic proximity to Semillon (the primary white variety of Sauternes and Hunter Valley). The same parentage hypothesis applies.
These genetic relationships — if confirmed as direct — would mean that two of the world's most important international white wine varieties have their ultimate origins in the ancient Lebanese/Levantine viticultural zone that the Phoenicians cultivated and spread across the Mediterranean. The wine culture that began in Lebanon may have contributed not just to the spread of viticulture but to the genetic foundation of the varieties that dominate global wine production today.
This research was conducted by the Institut National de Recherche Agronomique (INRA) at Domaine de l'Époisses, 21110 Bretenière, France, in collaboration with Lebanese researchers. The Lebanese viticulture genetic research is ongoing.
The wine-Islam dynamic in Lebanon
Lebanon is a country with a Muslim majority (approximately 54% of the population, roughly equally divided between Sunni and Shia communities) and significant Christian minorities (Maronite Catholic, Greek Orthodox, Greek Catholic, Armenian, and others — collectively approximately 40%). The wine industry is conducted primarily within Christian communities, though it operates under general Lebanese law which does not prohibit alcohol production or sale.
Lebanese wine has historically been produced by Christian families and communities, and the major wine estates (Château Musar — Hochar family, Maronite; Château Ksara — founded by Jesuits; Château Kefraya — de Bustros family, Greek Catholic; Massaya — Ghosn and Brunschwig families) reflect this pattern. The alcohol industry is legal, regulated, and coexists with the Muslim population in the pluralistic Lebanese social framework, though it occupies a culturally specific space within Lebanese society.
