Learn how coffee roasting transforms green beans into flavorful coffee, the main roasting methods, and what defines each roast level.

Ever wondered why your cup of coffee smells incredible but the raw green beans smell nothing like it? The secret isn’t in the bean itself—it’s in how it’s roasted.

So how does roasting actually work, what tools are used, and what defines light, medium, or dark roast? Let’s break it down.
