Introduction to Three Roast Levels of Coffee Beans

One of the core variables that shape coffee flavor is roast level. Different roast levels of coffee beans from light to dark deliver distinctly different taste experiences even from the same batch. Roast levels are generally categorized into three basic types: light roast, medium roast and dark roast. For a more precise description of the roasting degree, they are often further divided into eight roasting stages. However, we will briefly talk about these three basic types of roast levels.

Sensory-wise, green coffee beans are almost tasteless. So normally they must go through a roasting process before selling. After roasting, the beans unfold brand-new and delightful flavors and aromas.

The coffee roasting process involves many factors that affect coffee flavor, such as roasting time, method, differences in roast degree, even the quantity of coffee beans used, and own experience and practical handling skills of roasters. Tiny differences even in seconds can lead to significant variations.

Light Roast: Bright, Acidic, and Fruity Taste

Light-roasted coffee beans are light brown closer to caramel. Because of lightly roasted, they retain the original flavors and acid layers of the coffee beans to the greatest extent.

Its flavor is bright, acidic, and complex notes like citrus, berries and flowers. With a tart taste profile and fine, gentle texture, they are as refreshing as fresh juice or light tea.

They are best suited for pour-over method, which can highlight their bright acidity and fresh fruit notes.

Using a pour-over coffee maker (such as Ceramic Dripper) helps to maximize the extraction of flavors from light roasted beans.

Medium Roast: Balanced flavor, Medium acidity

Medium roasted coffee beans are brown like chestnut, with a moderate roast level. While retaining some of the original flavors, they develop richer, more mature aromas.

They have a well-balanced aroma, with notes of ripe fruits, caramel and nuts. The taste is refreshing, with a harmonious blend of sweetness, acidity and bitterness. It is widely popular among the general public.

Medium roast beans are suitable for a variety of methods including pour-over, French Press, espresso and cold brew.

French press coffee is mellow and smooth while espresso coffee made by espresso machine has intensely rich flavor and thick texture. The King Duke Ceramic French Press is recommended for medium roast coffee beans with a built-in hourglass timer in the handle, allowing you to precisely control the steeping time for a rich, aromatic coffee experience.

Dark Roast: Bold, Full-Bodied and Smoky Taste

Dark-roasted coffee beans are are dark brown, even close to a blackened color like chocolate, with a shiny, oily surface. The caramelization reaction is fully developed during the roasting process, resulting in mild acidity and prominent bitterness.

They emit aromas of dark chocolate, caramel and nuts, with a very bold and smoky taste.

It is recommended to use an espresso machine or moka pot. Dark roast beans are excellent choice for making latte art coffee. Using cold brew coffee maker can also bring out their rich and deep texture.

An espresso machine can transform dark roasted beans into a more intense, full-bodied coffee, ideal especially for coffee lovers who enjoy rich, bitter, chocolate, or smoky flavors.

Roast level is like the "invisible flavor blender" of coffee. Whether you like the fresh acidity of light roasts, balanced layers of medium roasts or rich caramelized aroma of dark roasts. Each endows coffee beans with distinctive taste souls and caters to diverse drinking scenarios and taste preferences.

For coffee lovers, there has no standard answer of roast level. The most important thing is to experience the unique charm that coffee brewed by coffee beans of different roast levels and keep discovering the flavor experience that suits you best.
