The bag is a tribute to all the pickers who get up before dawn to work in rose fields every morning from mid May to mid June. They gently pick the petals by hand, at that early hour the petals are protected by dew which prevents their perfume from evaporation. After that the petals must be processed through steam distillation within 24 hours to create the best quality and quantity of oil. It takes about 4,000 kilograms of rose petals to produce one kilogram of rose oil which makes Rose Absolute oil amongst the most expensive perfume ingredient in the world.
