Dark roast coffee beans are roasted to a temp of 430-440°F until they are dark brown with an oily sheen. The brewed coffee will be rich, robust, and full-bodied.
Medium roast beans must reach a temp between 400-430°F, resulting in a medium, brushed matte brown color. The brewed coffee is be balanced, slightly sweet, and not overbearing in flavor.
FLAVOR
Dark roasts carry an earthy, nutty, and chocolatey taste. The flavor comes from the roast itself instead of the bean. Medium roasts are more focused on highlighting the unique flavor of that specific bean. A dark roast will have more bitter undertones, while a medium roast will lean more acidic.
BEST BREWS
Dark roasts are perfect for espresso and espresso-like coffees. Many agree that the best way to enjoy this roast is as a Cuban coffee. Medium roasts are smooth enough to be enjoyed black but flavorful enough to handle some dairy or sweetener. These are a great choice for iced coffee and cold brew.
