Coffee Affectation

Coffee alters the taste of foods eaten contemporaneously. Caffeine has nothing to do with it.

Sense of smell remains unaffected by coffee. But people “became more sensitive to sweetness, and less sensitive to bitterness,” reports flavor researcher Alexander Fjældstad. “It’s probably some of the bitter substances in the coffee that create this effect. This may explain that if you enjoy a piece of dark chocolate with your coffee, its taste is much milder, because the bitterness is downplayed and the sweetness is enhanced.”
