Is coffee a heterogeneous mixture

Coffee is a complex mixture of hundreds of different compounds, including acids, essential oils, alkaloids, and phenolic compounds. While all these compounds contribute to coffee’s unique flavor, aroma, and body, they also make coffee a heterogeneous mixture. The different compounds in coffee are not evenly distributed throughout the mixture.

Instead, they tend to segregate into different layers. The lightest and most volatile compounds, like the essential oils, are found in the upper layers of the mixture, while the heavier and more dense compounds, like the alkaloids, are found in the lower layers. This segregation of different compounds is what gives coffee its unique flavor profile.

When you take a sip of coffee, you’re not tasting all of the different compounds in the mixture. Instead, you’re only tasting the compounds that are in the upper layers of the mixture. So, is coffee a heterogeneous mixture?
