Red chili is a spicy note that adds heat, texture, and aromatic energy to a fragrance. It may feel sweet, dry, peppery, resinous, herbal, smoky, or slightly medicinal depending on the material. In perfumery, spices create contrast, deepen the heart, and help bridge fresh top notes with warm woody or amber bases. Red chili pairs especially well with citrus, rose, tobacco, vanilla, oud, sandalwood, patchouli, leather, and balsamic resins.
