Light, medium or dark: roast style is one useful guide to how a coffee might taste, but your own preference always has the final word.
A spectrum of possibilities
A darker roast often brings deeper, toasted flavors. A medium roast can balance sweetness and body. Origin, processing and your brewing method also shape the result, so a roast label is only the beginning.
Let your taste lead
Try two coffees side by side using the same recipe. Notice the body, sweetness and finish. There is no perfect answer: the best coffee for you is the one you look forward to drinking.
