Have you ever wondered why coffee tastes intensely bitter to some people but not to others? A recent study by Northwestern University and QIMR Berghofer Medical Research Institute reveals that genetics play a significant role in our perception of coffee’s bitterness. Researchers found that individuals with a heightened sensitivity to caffeine’s bitterness—due to genetic variations—are more likely to enjoy and consume coffee. Surprisingly, rather than deterring them, this bitterness reinforces their preference for coffee, linking taste to its stimulating effects. This groundbreaking discovery helps explain why our coffee experience varies so much.
