Understanding coffee roast levels is key to finding your perfect cup. The roasting process transforms green coffee beans into the aromatic brown beans we know, and the degree of roasting dramatically affects flavor, acidity, body, and even caffeine content. Contrary to popular belief, lighter roasts actually contain slightly more caffeine than dark roasts.

Fruity, Floral, Tea-like
Light roasts preserve the most origin characteristics, showcasing the unique flavors of where the beans were grown. Expect bright acidity with delicate floral and fruity notes.
Medium-Light Roast
Balanced, Nutty, Citrus
A transitional roast that balances origin flavors with the beginning of roast development. Nutty and citrus notes emerge alongside the natural bean character.

The most popular roast level in America. Medium roasts strike a perfect balance between origin flavors and roast character, with sweet caramel and chocolate notes.
Medium-Dark Roast
Rich, Spicy, Bittersweet
Roast flavors become more prominent with rich, spicy, and bittersweet notes. The natural oils begin to surface on the bean, creating a fuller body.

If you prefer bright, complex flavors...
Go for light roasts. They showcase the origin characteristics of the bean and offer nuanced, tea-like flavors with high acidity. Ideal for pour-over enthusiasts.
If you want a balanced, everyday coffee...
Choose medium roasts. They offer the best of both worlds with caramel sweetness, moderate acidity, and approachable flavors. Perfect for drip coffee makers.
If you love bold, intense flavors...
Opt for dark roasts. They deliver smoky, bold flavors with a heavy body and low acidity. Ideal for espresso-based drinks and those who add cream and sugar.
If you prioritize caffeine content...
Surprisingly, light roasts have the highest caffeine content by weight. However, the difference is minimal in a typical cup. Brewing method and coffee-to-water ratio matter more.
