Coffee beans undergo different changes at each roasting stage.During the process of roasting green coffee beans into mature beans, as moisture is lost, they gradually go through dehydration, yellowing, then first crack and rolling first crack. Because the moment first crack begins means the coffee beans have already matured, if at this point we are not ready to stop and still want to continue cooking, then the coffee beans will also go through second crack and rolling second crack.
From the image, it can be seen that the roast level of coffee beans is divided into eight categories, with numbers going from large to small and roasts going from light to dark. Everyone can just take a quick look; in real life we do not often use this, because it is very difficult for us to judge by naked eye what the color value of coffee beans is or what roast it belongs to. Moreover, coffee will also be affected in the degree of browning during roasting due to differences in the sugar content of the surface layer. If we rely only on color to distinguish them, it is very easy to cause misunderstanding.
Therefore, this value can only serve as a roasting reference for roasters. Generally speaking, if we want to judge the roast level of a coffee bean, in addition to its external color, we also need to combine the bean's shape and taste in order to draw a conclusion about its roast level, and then simply classify it as: light, medium, and dark roast.
Light roast refers to beans discharged during the period from the middle of first crack to just after first crack ends. It can be tasted from
Front Street Red Cherry
,Front Street Kenya
,Front Street Rwanda
these three coffees! At this time, because the organic acids in the beans have not been completely decomposed, we can feel obvious acidity in the coffee, while bitterness is relatively low, and the aroma is very complex and rich.
Medium roast refers to coffee beans discharged after first crack ends and before second crack begins. You can try Front Street Mozart, Front Street Strawberry Candy, and Front Street Sidra. Because these coffee beans have undergone more caramelization reactions, the proportion of acidity in the whole cup of coffee will decrease. Compared with light-roasted coffee beans, they have less fruity acidity and a higher sweetness! The complexity of the aroma will also increase somewhat, which instead makes other flavors more prominent!
Dark roast refers to beans discharged after second crack begins. Because this type of bean has undergone a large amount of caramelization reactions, the flavor is mainly bitterness, with obvious sweet aftertaste, high body, and a full mouthfeel. Typical representatives are
Front Street Golden Mandheling
,Front Street Classic Espresso Blend
. The aroma released by the coffee is more uniform, mainly chocolate, nuts, and cocoa, not as rich and complex as the above light and medium roasts.
