In perfumery, barley offers warm, cereal notes with coumarinic and torrefied characteristics. Its top note has a fruity, rum-like character, making it ideal for supporting red fruit compositions. It is especially useful in gourmand fragrances thanks to its roasted facets that add depth and warmth.
Barley is one of the most widely cultivated cereals globally. In 2017, its production was estimated at 150 million tons, making it the fourth most cultivated crop in the world after rice, corn, and wheat. It serves as the primary raw material for malt production (note that malt is not a plant, but a processing method for cereal grains to separate sugars).
Botanically, barley belongs to the grass family (Gramineae) and the genus Hordeum.
