Bulgaria is one of the biggest producers of rose oil in the world. The reason hidden in the high qualities of the Bulgarian Kazanluk rose, a special type, which was cultivated in the country after many years of production and development. The Bulgarian roses are inheritors of the so called Damascena rose that was brought in the country ages ago. The rose oil is called "the liquid gold" of Bulgaria and used mainly for the making of perfumes, chocolates, liqueur and jam. The rose oil is three times more expensive than the gold. One kilogram rose oil is extracted from 3,000 kg of roses, which means that for one gramme of rose oil more than 1300 rose blossoms should be used! The Valley of Roses (Kazanlak region) is one of the biggest producers of rose oil in the world. The conditions in Kazanlak proved to be more favourable for the cultivation of the rose than those in its own country of origin - Tunisia.
