Medium roast coffee is a brown color and rarely has an oily surface. These coffees have a medium acidity and body, as well as a rounded flavor profile. Roasting to this level also preserves many of the unique flavors of the coffee’s origin, but it also begins to reach into the deep caramel sweetness of a longer roast. As a result, these coffees are balanced, well rounded, and are slightly darker and sweeter. Some of those bright notes of a light roast may be eliminated, but it’s a trade-off for balance.
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.
