Tonka bean is a warm, intoxicating scent that’s often compared to vanilla. Both are popular and enticing base notes for some of our favorite candle scents, but many people think the smell of tonka bean is more complex and interesting, as is the story behind this humble legume.
The tonka bean may not be a household name like vanilla, but it shares an enticing, temptingly sweet scent reminiscent of everyone’s favorite baking spice With its rich, vanilla-like fragrance complimented by almond undertones, this tropical bean has made its mark as a captivating ingredient
While vanilla originates from an orchid fruit, the tonka bean comes from a tree native to South America. The seed of the Dipteryx odorata tree, tonka beans grow in pods similar to vanilla beans. They thrive in the warm, humid climate of the Venezuelan rainforests.
Tonka beans go by many names, like “Dutch vanilla” and “butter vanilla” for their addicting creamy vanilla notes. Their scientific name comes from the Greek words dipteros (“two-winged”) and odoratus (“fragrant”).
The beans are small, hard, and black on the outside when dried. When split open, an enticing aroma wafts from the wrinkled, brown-black interior.
This bean has an ancient history as a coveted fragrance and flavoring. The indigenous Tupi people of Brazil first used tonka beans to scent clothing and blankets. European colonizers brought them back home in the 1500s prizing them as a precious spice.
Could Tonka Bean Be a Vanilla Dupe?
With its signature vanilla bouquet, it’s no wonder tonka bean was used as an adulterant and substitute for precious vanilla in the 19th century. When vanilla prices skyrocketed worldwide, tonka beans provided a more affordable alternative to satisfy the craze for the vanilla flavor.
Baked goods, confections, and perfumes could all be made with tonka instead of vanilla. Some dishonest vendors even went so far as to secretly blend small amounts of tonka into their vanilla extracts and powders to increase profits.
Does tonka bean smell and taste like vanilla? With its sweet, creamy, vanilla notes, tonka is undeniably similar. But side-by-side, their scents present distinct differences.
Tonka Bean’s Distinct Aroma: vanilla’s Richer, Sweeter Cousin
Tonka bean features a more full-bodied, sugary vanilla fragrance than vanilla pods themselves. The tonka aroma feels almost syrupy, like a vanilla bean drenched in caramel. Its vanilla tones are smooth and mellow.
Rather than a sharp, singular vanillin smell like pure vanilla extract, tonka bean has extra layers. Almond, cinnamon, clove, and honey play off the vanilla notes, adding warmth and depth. The vanilla is more buttery in tonka, almost like toffee or frosting.
Tonka also has a uniquely sweet tobacco character. In fact, tonka bean contains the aromatic compound coumarin. This gives tonka a subtle cinnamon cookie-like scent, as coumarin is also present in cinnamon cassia. Coumarin adds a cotton candy cloud to the tonka aroma.
The Secret Ingredient: Tonka Bean’s Magical Coumarin
Coumarin is the key ingredient that sets tonka beans apart from vanilla. Along with its sweet, edible notes, coumarin also lends itself perfectly to perfumes.
It provides excellent fragrance fixative properties to hold scent. Tonka quickly became a trendy perfume additive in the late 19th century. Coumarin became essential for its rich, sweet aromatic qualities.
However, later safety concerns over liver toxicity led to regulations around coumarin. While food regulations vary worldwide, most limit the allowed coumarin content. This restricts, but doesn’t eliminate tonka bean’s use as a flavoring.
In perfumery, coumarin remains an integral component of classic fragrances like Guerlain’s Shalimar. Thanks to its unparalleled fragrance abilities, its carefully measured use continues in fine perfumes today.
Indulging in Tonka Bean’s Distinctive Aroma and Flavor
Tonka bean brings its own complexity to any recipe. With an exceptionally sweet, spicy, and nutty tropical aroma, it’s ideal for pairing with fruits, spices, chocolate, caramel, and vanilla. It also complements coffee, red wine, and liquors.
The beans can be chopped or grated to release their precious oils and fragrance. Look for them with vanilla beans in the spice aisle or gourmet stores. Tonka extract and syrup allow for easy use in drinks and baked goods.
Some delicious ways to enjoy tonka beans:
- Black tea infused with tonka bean slivers and warming spices like cinnamon
- Crème brûlée topped with grated tonka bean and orange zest

Cultivating Responsible Enjoyment of Precious Tonka Beans
With its captivating scent and flavor, it’s not surprising that tonka beans were overharvested in the past. Their wild habitat diminished drastically, demonstrating the importance of sustainable practices.
Many organizations now work directly with indigenous harvesters in the Amazon to encourage responsible tonka bean cultivation. This maintains the plants and tree cover needed to support these ecosystems.
When sourcing tonka beans, look for fair trade and sustainably wild-harvested. Tonka beans can also be harvested from responsibly managed agricultural areas. Prioritizing social and environmental welfare helps preserve tonka beans for generations to come.
Tonka Bean: A Bean to Treasure
While the tonka bean may not be as famous as vanilla, it’s just as worthy of being treasured, savored, and enjoyed responsibly. With its transporting tropical aroma and rich complexity, tonka bean brings its own special enchantment.
Rather than just an imitation of vanilla, this exotic bean has carved out its own niche. There’s simply no substitute for the tonka bean’s singular creamy, amaretto-like decadence. It fills any recipe with a touch of luxury, nostalgia, and wanderlust.
With its sumptuous vanilla-caramel notes edged with spices and florals, the tonka bean remains unmatched. Next time you want to add something special to a dish, reach for the tonka beans and enjoy their magic.
Where Does Its Scent Come From?
Tonka beans are seeds from the tree Dipteryx odorata, which is also known as “cumaru,” “kumaru,” or “Brazilian teak.” After the fruits are harvested, the seeds are removed, dried, and cured, which produces these black, wrinkled beans that are smooth and brown on the inside.
The essence of tonka bean is derived from coumarin. When tonka beans are dried and cured in rum, small colorless crystals of coumarin can be extracted.
While coumarin has a bitter taste, it smells pleasantly sweet and aromatic. Coumarin gives tonka bean its sweet odor resembling that of vanilla. At the same time, it also gives off a herbaceous scent reminiscent of freshly mown hay.
Other plants, like lavender, strawberries, apricots, vanilla, cinnamon, and sweet clover, also have small amounts of coumarin. So even if you’ve never smelled tonka bean before, you might think the smell is kind of familiar.
What Does Tonka Bean Smell Like?
Tonka bean has a pleasant, natural smell that is a mix of sweet, spicy, nutty, herbaceous, and woody.
Its scent is complex and sweet like vanilla, with enticing notes of spices and tobacco. It can be warm, inviting, and even seductive at times, depending on how it’s mixed with other scents.
Most can agree that the smell of tonka bean itself is distinctively multifaceted. We like to think of tonka bean as an intoxicating mix of:
- Softly sweet and milky smooth
- A subtle spiciness with hints of cinnamon and nutmeg
- Warm and herbaceous, like a summer meadow
- Slightly nutty, like toasted almonds
- A tart accent of wild cherry
If one were to compare it to vanilla, the smell of tonka bean is not as overpoweringly sugary. Instead of being creamy and sweet, tonka bean has a more neutral sweet tone with hints of almond, cherry, cinnamon spice, and sweet hay.
Tobacco bean comes from both the Fougère (Ferns) and Amber families, which are two of the six main fragrance families. For example, woody and herbaceous Fougère scents are based on the coumarin accord that comes from tonka beans. On the other hand, because it smells like vanilla, it is at the heart of many rich and exotic amber scents.
Tonka bean is a base note used in some of our favorite high-end candle scents, like Home and Josephine. It has a rich, warm, and deep scent.
