Roasting coffee shares similarities with cooking and baking. Just like when you cook at home, you consider the quality of ingredients, the tools you use, your skill level, and the cooking methods employed. Coffee roasters take unroasted green coffee beans—the dried and hulled seeds of the coffee cherry—and roast them to perfection over a span of roughly 10-15 minutes. In this article, we’ll explore this process in detail and clarify what distinguishes light, medium, and dark roasts.
Think of coffee roasters as specialized ovens. Similar to baking, you begin by preheating the oven, then roast your ingredients to produce something delicious. In coffee roasting, the roaster is heated to about 400°F before adding the green coffee beans.
During the first 7 minutes of roasting, the objective is to eliminate any remaining moisture from the beans. This is crucial because the caramelization of sugars and flavor development through the Maillard Reaction, which contribute to the coffee’s delightful taste, cannot occur if the beans retain water.
Around the 9-10 minute mark, the beans reach what is known as “first crack,” releasing stored energy. This point gives the roaster significant control over the flavor profile, referred to as “development.” After first crack, the acidity and fruity notes typically diminish, while sweet flavors like caramel and chocolate become more pronounced. This is where the distinction between light, medium, and dark roasts becomes apparent.
Light roasts are typically reached after a shorter roasting period, around 10-11 minutes post-first crack. These coffees tend to have higher acidity and fruity flavors and a generally lighter body. They are ideal for those who enjoy exploring complex and unique flavor profiles. Most of our single-origin coffees, sourced from specific places, farms, or co-ops, fall into this light roast category as our roasters aim to preserve their distinctive characteristics.
Medium roasts are roasted longer than light roasts, retaining some fruity flavors and acidity while developing additional sweetness. This style is perfect for those who appreciate a chocolatey taste combined with enough acidity to keep things lively. Many of our blends, such as Founder’s Blend, fall into this category, making them excellent choices for daily coffee enjoyment.
Dark roasts, on the other hand, are roasted the longest—typically around 15-16 minutes. These coffees generally have less acidity compared to medium roasts, with dominant flavors of caramel and dark chocolate. They are suited for those who enjoy a bold cup of coffee that can easily be complemented with milk. A few of our roasts, such as French Roast, fit this category as robust breakfast options.
Ultimately, there are no strict definitions separating light, medium, or dark roasts. Some of our coffees may blur the lines between these categories to achieve a balanced flavor. Our primary aim is to provide you with a harmonious and sweet cup of coffee, offering choices that cater to your taste preferences. Cheers!
