Yuzu is a citrus fruit native to East Asia, particularly popular in Japan, Korea, and parts of China. It resembles a small grapefruit with an uneven skin, and can range in color from yellow to green depending on its ripeness. Yuzu is noted for its unique aroma and flavor, which distinguish it from other citrus fruits.
The scent profile of yuzu is complex and highly aromatic. It combines elements of lime, lemon, mandarin, and grapefruit. Yuzu's fragrance is tart and bright, with distinct floral notes and a hint of pine, making it markedly invigorating. The aroma is often described as refreshing, zesty, and slightly herbaceous, which is why it's frequently used in perfumery and aromatherapy to impart a clean, citrusy, uplifting scent.
