Vanilla fragrances are often associated with sweet, nostalgic notes, but vanilla’s scent is complex, featuring balsamic, woody, and bitter tones. Vanillin provides the characteristic sweetness, but vanilla is also used in woody, spicy, and oriental perfumes. Native to Mexico and now produced in Madagascar, Indonesia, and China, vanilla’s aroma varies by region: Tahitian is fruity and floral, Bourbon is intense with high vanillin, Indonesian has a smoky note, and Mexican is woody. Vanilla is a key ingredient in many perfumes, known for its versatility and rich, diverse scent profile.
