Coffee roasting is both an art and a science, a delicate process that shapes the flavor profile and aroma of the coffee we enjoy. At Kaleido Roasters®, we honor this craftsmanship by offering state-of-the-art roasting equipment, including the M1 Artisan System (50g-200g), engineered for precision and versatility. Whether you’re a home enthusiast or a professional roaster, understanding the three primary degrees of coffee roasting is essential for taking your coffee experience to the next level. The roast level directly influences the flavor, acidity, body, and overall enjoyment of your cup, making it crucial to master.

The Three Basic Degrees of Coffee Roasting

Coffee beans go through a remarkable transformation during the roasting process. As they heat up, they undergo chemical and physical changes that define their final flavor characteristics. The degree of roast—light, medium, or dark—plays a significant role in determining these qualities, and understanding each one can help you tailor your coffee to your exact preferences. Let’s explore these three basic roasting levels in greater detail.

Light Roast

Lightly roasted beans are easily recognizable by their light brown color and lack of oils on the surface. This roast is often associated with preserving the unique characteristics of the coffee bean, as the roast time is kept relatively short. The natural flavors—floral, fruity, or bright—remain prominent, with a pronounced acidity that can range from tangy to citrus-like.

Light roasts are especially popular for single-origin coffees, where the terroir and origin flavors of the beans shine through. This roast level is ideal for those who appreciate a more nuanced and complex cup of coffee. At Kaleido Roasters®, we recommend the M1 Artisan System for achieving the perfect light roast. With its precise temperature control and small-batch capacity (50g-200g), this system allows roasters to dial in the perfect roast every time, ensuring consistency and the preservation of delicate flavors.

Medium Roast

Medium roasts strike a perfect balance between acidity and body. These beans are typically medium brown in color, and their flavors tend to be more rounded and well-balanced. The acidity present in the light roast is mellowed out, while the body becomes fuller and smoother. Medium roasts are the most popular choice among coffee drinkers, known for their versatility in flavor and broad appeal.

Often referred to as the “American roast,” the medium roast is a favorite in everyday brewing, offering a flavor profile that works well in both drip coffee and espresso-based drinks. The M1 Artisan System excels in this range, allowing for easy monitoring of bean development to achieve consistently perfect medium roasts. Whether you’re preparing coffee for a relaxing morning or serving a busy café crowd, the M1 ensures every cup is rich, balanced, and satisfying.

Dark Roast

Dark roasted coffee beans are the boldest of the bunch, with a deep, dark brown or almost black color and a shiny, oily surface. The roast process for dark beans takes longer, and the natural flavors of the coffee are overshadowed by the roasting process itself. As a result, dark roasts feature more intense, smoky, chocolaty, or caramelized flavors, and the body is typically heavier and more robust.

Dark roasts are particularly popular for espresso and strong coffee brews, where the full-bodied and intense flavors stand up to milk and sugar. However, dark roasting requires careful attention to avoid over-roasting or burning the beans. The M1 Artisan System from Kaleido Roasters® makes this easier with its precise control over temperature and air circulation, ensuring that beans are roasted uniformly and without any risk of charring. This guarantees a smooth and enjoyable dark roast every time, perfect for those who love bold flavors without the bitterness or burnt aftertaste.
