Espresso is coffee of Italian origin, brewed by forcing a small amount of nearly boiling water under pressure through finely ground coffee beans. Espresso is generally thicker than coffee brewed by other methods, has a higher concentration of suspended and dissolved solids, and has crema on top.
𝗗𝗔𝗥𝗞 𝗥𝗢𝗔𝗦𝗧 𝗖𝗢𝗙𝗙𝗘𝗘:
Dark roast coffee beans stay on the roasting machine for a longer time or at a higher temperature. This means the beans will lose more moisture, making them less dense, less caffeinated, and more single-note in flavor. Dark roast coffees taste how you think coffee tastes, reminiscent of an old-school diner cup, or what your parents make in the drip machine at home. And since the beans are roasted long enough to develop their oils and bring them to the surface, the body of your coffee will be thicker.
