Coffee Aroma Kit Guide: Bottles 10 to 18 Explained

Ever sniffed a coffee and caught something sweet like vanilla—or sharp like blackcurrant—but couldn’t quite place it? The Le Nez du Café aroma kit (bottles 10–18) helps you identify those elusive scents that pros use to evaluate coffee. Whether you’re cupping at home or training your palate, these reference aromas let you name what you’re actually smelling.

In bottles 10 to 18, you’ll find 9 key aromas that frequently appear in specialty coffee—from creamy vanilla to tangy blackcurrant and bright citrus. Each has a specific origin, chemical compound, and typical coffee expression. Below is a clear breakdown of each one.

10. Vanilla – Sweet, Warm, and Bean-Derived

Vanilla is a sweet, buttery, and resinous aroma from orchid pods. Its key compound is vanillin, found as crystals on the bean’s surface. In coffee, it adds body, smoothness, and balances other aromas—especially in high-quality Arabica. It shows up in Brazilian, Kenyan, Salvadoran, and Papua New Guinean coffees, often lending a soft, exotic richness.

11. Tea-Rose / Redcurrant Jelly – Floral and Tart

This aroma comes from β-damascenone, a compound in Bulgarian roses and some coffees. It smells like Turkish rose or redcurrant jam and appears more in Arabica than Robusta, especially in wet aromas. It’s notable in Salvadoran Pacamara and Guatemalan coffees, often blending with jasmine notes.

12. Coffee Blossom – Delicate and Jasmine-Like

The scent of coffee flowers resembles orange blossom or soft jasmine. Though often too faint to catch, it’s present in top coffees. You might sense it in Colombian, Venezuelan, Guatemalan, Ethiopian Harrar, and Indonesian or Papua New Guinean beans—subtle but adding floral depth.

13. Coffee Pulp – Fermented and Wine-Like

This aroma comes from fermenting coffee fruit off the beans. It gives off winey, volatile acidity—key in washed processing. Caused by compounds like 2-methyl and 3-methyl butanoate, it’s vital for coffee aroma but can turn sour if overdone. It’s prominent yet refined in well-processed Colombian and Kenyan coffees.

14. Blackcurrant-like – Fruity with Sulfur Notes

This bizarrely vibrant aroma resembles blackcurrant, sometimes with herbal or sulfur undertones. Linked to 3-mercapto-3-methylbutyl formate, it’s a hallmark of great coffees. It shows in dry aromas of both Arabica and Robusta, and lingers in the cup. Found in Hawaiian Kona, Kenyan Kitalé, Jamaican Blue Mountain, and Costa Rican beans.

15. Lemon – Bright and Citrusy

Lemon aroma comes from terpenes and aldehydes in the peel. In coffee, it adds freshness, elegance, and vibrancy through compounds like 1,1,3-trimethyl cyclohexane. It’s often more noticeable in the cup than the nose. Prominent in Kenyan AA, Colombian Caldas, Guatemalan, and Papua New Guinean Sigri coffees.

16. Apricot – Stone Fruit Elegance

This rich, sweet scent ranges from fresh to dried apricot. Created by compounds like benzaldehyde and linalool, it gives coffee a refined, high-quality feel. Subtle but distinctive, it’s a marker of excellence—best sensed in Ethiopian Sidamo.

17. Apple – Crisp and Fermented

The smell of freshly peeled apple, with slight fermentation notes, mirrors compounds also in coffee. It’s a common background fruit note, especially in Central American and Colombian coffees, and blends naturally with coffee pulp. Also detectable in fresh Haitian coffees.

18. Fresh Butter – Creamy and Smooth

This aroma stems largely from diacetyl (butanedione), giving a melted butter impression. It’s a hallmark of quality Arabica, enhancing mouthfeel and aroma. Especially strong in wet aromas and twice as noticeable in Arabica vs Robusta. Present in Costa Rican, Colombian, Puerto Rican, and select Brazilian and Kenyan coffees.
