French Roast is the darkest roast level and is characterized by a bold, intense, and smoky flavor with a slightly bitter aftertaste. The beans are roasted to the point of almost being burnt, which gives them a distinct smoky flavor and a full-bodied texture. The high roasting temperature reduces the acidity and enhances the body, making French Roast coffee a good choice for those who prefer a strong, full-bodied coffee.
Dark Roast, on the other hand, is a broad category that encompasses several different roast levels, including French Roast. Dark Roast coffee is characterized by a bold, rich flavor, but it is typically not as intense or smoky as French Roast. The roasting process for Dark Roast coffee may vary, but the beans are typically roasted for a longer period of time than medium roast coffee, resulting in a darker color and a bolder flavor.
In summary, French Roast is the darkest and boldest type of Dark Roast coffee and is known for its intense, smoky flavor and full-bodied texture.
