Somewhere between the Balkans and the Sredna Gora mountain ranges in Central Bulgaria lies what is known as the Valley of Roses. The picturesque valley is surrounded by a number of old-fashioned towns where people have been planting, picking and processing roses for over 300 years. There is something about the climate of the area that creates the optimal conditions for what is considered to be some of the best rose essential oil in the world. Every year between May and June, the skilled harvesters wake up at dawn to carefully pick the roses while the petals are still covered in the morning dew. Each rose has 30 petals, and it takes 4000kg of rose petals to produce 1kg of 100% pure distilled rose essential oil.
