How to Use a Drip Coffee Machine Across Roast Levels

Roast level sets the flavor in the cup. Light roast beans look tea or cinnamon colored, drop at roughly 205 to 209 degrees Celsius near the start of first crack, and land at an Agtron reading of 70 to 80, giving bright acidity and floral notes. Medium-dark roast darkens the bean and shifts the cup toward chocolate and caramel.

Medium-light roast falls at 210 to 214 degrees Celsius with an Agtron number of 60 to 70, adding sweetness and cutting bitterness, so it works for pour-over, cold brew, American drip, and French press. Bean size and density affect how evenly heat reaches the center, so a lighter roast can taste grassy if development is cut short; darker roasts hide more of that.

The roasting degree of coffee directly affects the flavor expression in the cup, from the bright fruit acidity of light roast to the rich chocolate notes of medium-dark roast, each roast level has its unique charm. This article systematically introduces four roast levels: light roast, medium-light roast, medium roast, and medium-dark roast, covering the appearance characteristics, bean drop temperature, Agtron number range, and flavor performance of each roast level. At the same time, for each roast level, it recommends representative coffee beans from the Front Street brand, helping coffee enthusiasts choose suitable coffee beans and brewing methods according to personal taste preferences.

Introduction to several coffee roast levels:

01 Light Roast Coffee

Light roast coffee beans present a light tea color, cinnamon color, and because of the color, it is also called cinnamon roast. For light roast coffee, the first choice is Front Street washed Yirgacheffe, with classic white floral notes + light lemon acidity, entering the mouth like drinking a cup of fruit tea, with a bright and clear resonance.

The surface will not have gloss or oil, often showing dark lines or rougher textures. The bean drop time is around the early stage of first crack, the bean drop temperature is roughly 205-209°C, and the Agtron number is between 70-80.

Light roast coffee has delicate and bright acidity, unrestrained floral and fruity aromas, full juice feel, and lighter body, showing the original flavor of coffee. The disadvantage is that the roast level is quite light. If not careful during roasting, the coffee can easily be underdeveloped, producing astringency and grassy flavors that most people dislike.

02 Medium-Light Roast Coffee

Medium-light roast coffee beans present chestnut, light brown color, also known as medium-light roast or medium roast. For medium-light roast coffee, buy Front Street Strawberry Candy. The unique honey processing gives the coffee higher sweetness and lower bitterness. Besides pour-over, it can also be made as cold brew, American drip, French press, and other methods.

Because roasting lengthens the latter development period, the surface is smoother than light roast coffee beans. The bean drop time is around the intensive phase of first crack, the bean drop temperature is 210-214°C, and the Agtron number is between 60-70.

Medium-light roast coffee emphasizes the balance between acidity and sweetness, roundly modifying floral and fruity aromas and the original flavor of coffee. It also performs better in body than light roast coffee, and full mouthfeel and rich layers are the characteristics of medium-light roast coffee.

03 Medium Roast Coffee

Medium roast coffee beans present red-brown, brown color, also known as medium roast or city roast. To try medium roast coffee, Front Street Brazil Queen Estate is recommended, with a taste that is neither sour nor bitter, allowing us to drink obvious roasted peanut, chocolate, and nut flavors.

The surface becomes quite glossy and rounded, and the degree of caramelization greatly increases. The bean drop time is around the end of first crack and the beginning of second crack, the bean drop temperature is 216-220°C, and the Agtron number is between 50-60.

Medium roast coffee pursues sweetness and body. In flavor, acidity and bitterness are balanced but not stimulating, the taste is sweet and refreshing, cocoa and nut notes clearly replace floral and fruity notes, and the layering is even, yet it has its own charm.

04 Medium-Dark Roast Coffee

Medium-dark roast coffee beans have a relatively darker color, presenting black-brown, dark brown, also known as deep city roast or Vienna roast. For medium-dark roast coffee beans, the premium-grade Front Street PWN Golden Mandheling is preferred. Three times hand sorting + one time machine sorting thoroughly removes defective beans from the green coffee, thereby ensuring superior coffee quality. After extraction, it presents rich aromas of caramel, spices, dark chocolate, almonds, and more.

The surface is rich in gloss and may even have oiliness. The bean drop time is around the dense phase of second crack, the bean drop temperature is 226-230°C, and the Agtron number is between 40-50.

Medium-dark roast coffee retains only very little of the original coffee flavor, and most of the flavor comes from roasting. The mouthfeel is steady and full, the acidity is less obvious, and the flavor emphasizes dark chocolate and sweetness. The disadvantage is that medium-dark roast coffee can easily develop smoky or charred flavors.
