Chateau Ksara is Lebanon's oldest winery. Its traditions can be traced back to 1857 when a group of Jesuit monks acquired the property. The Jesuits applied their knowledge of science and agriculture to plant French vines as well as developing two kilometres of Roman caves that proved ideal for the storage of wine. The Jesuits sold the winery to its current owners in 1973. Ksara is now the most modern winery in the region as well as the largest producer in the country. Their annual production is over 2.8 million bottles and they sell their wines in more than 40 countries worldwide. Chateau Ksara is certified ISO 9001 and ISO 2200.00 for its viticulture, production and sales guaranteeing quality and consistency year on year.
