The short answer
Light roasts are bright, acidic and keep more of the bean's origin character. Medium roasts are balanced, the everyday all-rounder. Dark roasts are bold, smoky and lower in acidity. Caffeine barely changes across roasts. Choose by flavour: light for fruit and nuance, dark for richness, medium for versatility.

What roast level actually changes
Roasting develops flavour through heat and time. The longer the roast, the more the bean's origin character gives way to the deeper, roastier notes of the roast itself. It is less about strength and more about the kind of flavour you want in the cup.
Light, medium and dark
- Light: bright and acidic, with the most fruit, floral and origin character. Great for filter and pour-over.
- Medium: balanced and approachable, with body and sweetness. The most versatile everyday choice.
- Dark: bold, smoky and low in acidity, with rich, roasty depth. A classic base for espresso and milk drinks.
The caffeine myth
Dark roast does not mean more caffeine. Roast level changes flavour far more than caffeine, and by weight the differences are small. If you want a stronger cup, adjust your coffee-to-water ratio rather than reaching for a darker roast.
