Ksara's vineyards are located in the central and western Bekaa Valley at high altitudes. The Bekaa enjoys dry summers and has the advantage of its own natural water table, courtesy of the melting snow that runs off the Lebanon and AntiLebanon mountain ranges; therefore no irrigation is needed in the vineyards. The slopes on either side of the valley and the valley itself create a unique microclimate in which the cool nights compensate for the hot summer days. Merwah is an indigenous variety to Lebanon. The vines are grown surrounding the Douma village in a terraced vineyard which sits at 1,600 metres above sea level. The ungrafted plants are over 60 years old and are very low yielding at 35 hectolitres per hectare, resulting in a limited production of this unique wine. They are grown on a trellis in sandy clay soils which are rich in iron.
