The degree of roasting of coffee largely determines the flavor of the coffee. When we buy coffee, the label will indicate the degree of roasting, such as light roasting and dark roasting. These are easy to understand. Some also indicate cinnamon roasting and city roasting, which is confusing. In this issue, Front Street will give you knowledge about the degree of coffee roasting.
There are many names for coffee roasting, such as French Roast, Italian Roast, City Roast... Among them, French Roast,Italian bakery, refers to the degree of roasting, not the origin of the coffee.
So-called French bakes usually refer to relatively lightEspresso roasting, while Italian roasting is a darker roasting degree. But in the United States, the roast called French Roast is usually incredibly dark, and the coffee tastes burnt, bitter, and deeply smoky, sometimes like drinking a cup of coal. Its strong bitter taste and unique roasting aroma are very suitable for making European coffee such as coffee au lait and Vienna coffee.
City roasting originated in New York. The coffee beans are bright brown in color and have a rich and mellow aroma with a balanced bitterness and sourness. It is a roasting level that is commonly consumed in coffee shops or at home. The Italian roasting degree is the strongest, the coffee beans are almost charcoal black, and you can taste the strong bitterness and rich taste, which is suitable forespresso, cappuccino.

Sharing ideas for Front Street blended coffee
At FrontStreet Coffee, you can find 4Front Street Italian Blend Coffee Bean, which are Front Street Sunflower Warm Sun Mix and Front Street Boutique.Italian blended coffee, Front Street Commercial Italian Blend Coffee and Front Street Basic Italian Blend Coffee. The Front Street Sunflower Warm Sun Blend is currently the most outstanding blend of coffee beans from Front Street. Let’s share how Front Street blends the Front Street Sunflower Warm Sun Blend coffee beans with a rich chocolate, wine aroma and vanilla flavor.
In this warm and sunny winter season, Front Street plans to make a blend that is suitable for both Pour over(V60) coffee and espresso. In terms of taste, we want this blended bean to have a tangy, pleasant aroma with a highly recognizable aroma, a thick mouthfeel with a touch of soft fruit acid, and a mid-to-high sweetness in the finish.
I thought about it and made a selection. I want beans with a more prominent aroma and a thicker texture. Are beans with special processing methods also a good choice? Anaerobic? Barrel fermented? There are thousands of varieties of beans in Ethiopia's production areas, and the flavors are more discoverable. Washed beans have bright fruit acid and a clean taste. Sun-dried beans have richer tropical fruits and a complex and thick taste. When I had no idea where to start, I thought that SOE had been made from wine barrel-fermented beans and sun-dried Front Street Yirgacheffe beans. The extracted taste was good, with fruit acid in the aroma, and a balanced taste without losing monotony and sufficient sweetness.
FrontStreet Coffee roasting curve analysis
When used for blended beans, they must have a body, sufficient sweetness, and be relatively balanced overall. Considering that the mixed blended beans may be unevenly roasted during the roasting process, the method of gradually lowering the heat during roasting is used so that the beans can develop simultaneously during the roasting process.
When the furnace temperature reaches 210℃, put the pot into the pot, open the damper to 4, firepower 200, temperature recovery point 1'30", 92℃; when the furnace temperature is 140℃, open the damper to 6; at this time, the bean surface turns yellow, the grassy smell disappears completely, and it enters the dehydration stage. When the furnace temperature reaches 180℃, adjust the firepower to 10, and open the damper to the maximum 10;
At 9'30", ugly wrinkles and black spots appear on the surface of the beans, and the smell of toast obviously changes to the aroma of coffee, which can be defined as the prelude to the first crack. At this time, you need to listen clearly to the sound of the first crack. The first crack will start at 10'38", and then develop to 3'40'' after the first crack. Cook at 197.5℃.
After cupping, hand brewing, and Italian extraction, this bean has soft acidity in the mouth, long-lasting sweetness, and sufficient sweetness. It has a rich aroma of chocolate, vanilla, cream, and obvious wine flavor. It has a clean and smooth taste and a medium mellow body. It is very suitable for the warm day blend beans I want in Front Street.
