The Brazilian tonka bean, derived from the seeds of the Dipteryx odorata tree native to South America, particularly Brazil, is a prized ingredient in perfumery and flavoring. The outer shell of the tonka bean is wrinkled, and inside lies the aromatic seed which, when dried, exudes a captivating scent and flavor. Its fragrance is complex, characterized by a sweet, warm base that blends notes of vanilla and almond, with hints of spicy cinnamon, cloves, and a touch of cherry. This rich, intoxicating aroma also carries undertones of tobacco and caramel, giving it a deep, creamy, balsamic quality.
Tonka beans contain coumarin, a natural compound that contributes to their distinctive hay-like, freshly cut grass aroma. In perfumery, tonka beans are often used to provide depth and persistency to fragrances, often found in the gourmand and oriental families where they add a sensual, smooth finish. The scent of tonka bean pairs particularly well with vanilla, amber, and sandalwood, making it a popular choice in the base notes of many fine fragrances for a lasting impression.
