Château Ksara, founded by the Jesuits in 1857, is Lebanon’s oldest ‘modern’ winery and the producer that laid the foundations of the current Lebanese wine industry. With vineyards located in the Bekaa Valley at 1,000–1,600 meters, it produces 3 million bottles annually, many of which are aged in the famous 2-kilometer, Roman-era caves that run under the winery. Committed to sustainability, Château Ksara is planting indigenous varieties at higher altitudes for enhanced terroir expression. Bee hives support biodiversity, while solar panels, insulated tanks, and underground ageing improve energy efficiency. Château Ksara blends tradition with innovation, ensuring its legacy as a leader in Lebanese winemaking.
