Roast Levels Explained

Understanding Roast Levels

Roast level is one of the most visible factors influencing coffee flavor. It determines the balance between origin character and roast-derived flavors. Lighter roasts preserve the bean's natural identity; darker roasts emphasize the roasting process itself.

Light Roast

Stopped shortly after first crack. Beans are light brown with no surface oil.

• Bright, vibrant acidity
• Origin flavors dominate — fruit, floral, tea-like
• Light body, clean finish
• Higher perceived complexity
• Popular in specialty coffee and pour-over brewing

Medium Roast

Developed beyond first crack but well before second. Rich brown color, minimal oil.

• Balanced acidity and body
• Sweetness peaks — caramel, chocolate, nuts
• Origin and roast flavors harmonize
• Versatile — works for espresso and filter
• The sweet spot for many coffee lovers

Dark Roast

Approaching or past second crack. Dark brown to nearly black, visible surface oils.

• Low acidity, heavy body
• Roast flavors dominate — smoky, bittersweet, charcoal
• Origin character diminished
• Bold, intense flavor
• Traditional in Italian and French roasting styles

Caffeine & Roast Level

A common myth: dark roast has more caffeine. In reality, caffeine content is remarkably stable across roast levels. Dark roast beans weigh less (more moisture lost), so by weight, dark roasts contain slightly more caffeine — but by volume (scoops), light roasts have marginally more. The difference is negligible.

Our Philosophy at Röstschmiede

We predominantly roast in the light to medium range because we believe in letting the coffee speak for itself. Our goal is to develop sweetness and balance while preserving the unique flavor fingerprint that the farmer, origin, and processing method created.
