The Art of Coffee Roasting

Of everything that shapes a cup of coffee, green beans account for about 60%, roasting for 30%, and extraction for 10%. Good roasting amplifies the unique character of the green beans while suppressing defective flavors; poor roasting can ruin even excellent beans. Since managing heat, time, and temperature during a roast is genuinely difficult, roasting remains a deeply complex craft - which makes its importance all the greater.

Coffee Flavor Profiles by Roast Level

What actually distinguishes light, medium, and dark roast coffee beans? FrontStreet Coffee breaks it down.

Light roasts favor bright, refreshing flavors with exceptionally varied expression: floral notes, fruity acidity, and certain tea-like qualities are the hallmarks. Medium roast aims for balance, pairing those fresh flavors with a fuller body. Dark roasts lean into that body, marked by intense smoky, chocolate, and woody notes carried on a heavy, full texture.

FrontStreet Coffee Recommendation

For the balanced middle ground, FrontStreet Coffee's Brazil Fazenda Rainha (Queen Estate) is a standout: the rare Yellow Bourbon variety from the world's largest coffee-producing country, medium roasted to reveal creamy peanut, chocolate, toasted bread, and sugarcane sweetness - smooth for pour-over yet equally at home in a moka pot or espresso machine.

If you prefer your medium roast on the sweeter, fruitier side, FrontStreet Coffee's Strawberry Candy blend pairs Costa Rican honey-processed coffee with Panamanian washed Geisha. Medium roasting preserves its orange-blossom honey aroma and rounded sweetness, and it shines as cold brew, pour-over, or espresso.
