Coffee scented candles are lovely on a grey November morning. But coffee has another job in the fragrance world. Perfume counters often hand you a little jar of coffee beans. The idea is that a sniff "resets" your nose between scents. It sounds clever. When researchers actually tested it, the coffee beans did no better than plain air. Here is what the study found, and what to do instead.
Coffee scented candles and the coffee bean myth
In 2011, a team led by Alexis Grosofsky tested the coffee bean trick. Their paper appeared in the journal Perceptual and Motor Skills.
Students smelled three fragrances over and over and rated them. Then each person sniffed coffee beans, a lemon slice or plain air. After that, they had to pick out a new scent from a set of four.
The coffee beans did not help. People who sniffed coffee did no better than those who sniffed lemon or just air. It was a small study, so it is not the last word. But nobody has shown the beans do anything special.
So why does the coffee bean trick feel like it works?
Coffee is strong and very different from perfume. It grabs your attention for a moment. That feels like a reset. In truth, your nose is simply getting a short break, and plain air gives you that too.
A candle coffee scent is a strong one
That strength is why coffee works well in a candle. A candle coffee scent is rich and roasted, and it carries across a room. It often sits with notes (the separate smells in a blend) like vanilla, caramel or nuts. These soften the bitter edge.
The flip side is that coffee can drown out softer scents nearby. If you burn a coffee candle in the kitchen, keep floral or fresh candles for another room.
How to compare candles and fragrances properly
Trying to choose between candles and fragrances in one go? After a few sniffs, they start to blur together. The fix is simple, and it is free.
- Smell no more than three scents at once
- Step outside or open a window between rounds
- Come back a little later and smell again
- Trust the one you still want to smell
Quick answers
Do coffee beans reset your sense of smell?
No good evidence says they do. In a 2011 study, people who sniffed coffee beans picked out a new scent no better than people who sniffed plain air or lemon.
How do you test candle scents without getting confused?
Smell a few at a time, then take a break in fresh air. Smell them unlit first. Coming back later gives your nose a fairer second go than any jar of beans.
Our 2026 Advent Calendar makes this easy. One door a day means one tealight a day, with a full night in between. No beans needed. Twelve fragrances, from Christmas Shortbread to Candy Cane, each get a fair hearing.
