In terms of roasting coffee beans, high-altitude coffee can adapt to deeper roasting because of its rich aroma substances, while low-and middle-altitude coffee beans are softer and less aroma-flavor substances than high-altitude coffee. If you want rich flavor and balance, try coffee beans that are moderately roasted at high altitude, and if you want to try coffee with low acidity and mild taste, try coffee at low altitude.

In terms of coffee roasting, high-altitude coffee has high hardness, moisture is more difficult to evaporate, and more firepower is needed for roasting, and you can also try deeper roasting. For the sake of flavor, low-altitude coffee as a single product should be careful not to roast too deeply. Avoid the bitter taste.

For coffee, different treatments also determine the depth of coffee roasting. At present, the more popular treatment methods are sun exposure, water washing and half-sun treatment, and different treatments also have a great impact on the taste and roasting degree of coffee.

For the roasting of coffee beans, the aroma and flavor of sun beans are easier to show in the first stage, while the water content is lower, so the baking degree of sun beans can be chosen in medium light and medium baking. On the other hand, many washed beans have high moisture content, hard beans, lower taste and balance, if the roasting is shallow, many exciting tastes may not be worn off, at the same time, the appearance folds of coffee beans are difficult to stretch, and the coffee expansion is poor, resulting in the taste not stretching enough. therefore, washed beans can choose relatively deep roasting.
