Why does coffee make us addicted to chocolate?

While the scientists did not observe any alterations in smell, they did highlight changes in taste. "When people were tested after drinking coffee, they became more sensitive to sweetness and less to bitterness ," explains Professor Alexander Wieck.
To rule out the possibility that the caffeine in coffee could be a factor, the researchers repeated the experiment using decaffeinated coffee. With the same result. "It's probably the bitter substances in coffee that create this effect," the author says. "This may explain our desire for a piece of chocolate with our coffee. Its much milder taste reduces the bitterness of the coffee, enhancing the sweetness," he continues. These results should ultimately provide a better understanding of how our taste buds work.
