First, it is very important to understand the different grades of coffee beans. Generally speaking, coffee beans are divided into four main grades: special grade, first grade, second grade and third grade. Special grade is the highest quality beans, usually with a distinct and complex taste, and is more expensive. First and second grades are relatively common and easier to find in the market. Third grade is a low-end product, usually used to make instant coffee or other processed products.

Secondly, there are several guidelines to pay attention to when purchasing. The first is to choose coffee beans that are fresh and well-preserved. Freshness is essential to maintaining flavor, so it is recommended to choose products that are fully packaged and not expired. The second is to choose the type that suits your taste needs and preferences (such as Arabica or Robusta) according to your favorite flavor. Finally, you can refer to the reviews and recommendations of other consumers and choose a brand or coffee beans with a good reputation.

Finally, the roasting technique. Roasting is the process of converting raw beans into coffee beans that can be used for brewing. Different degrees of roasting will bring different flavors and tastes. Generally speaking, light roasting will retain more original flavors, but it may also bring a sour or spicy taste; medium roasting is more balanced and common in most commercial coffees; deep roasting usually has a strong and bitter character. Therefore, when performing manual roasting at home, you need to choose the degree that suits your taste needs according to your personal preferences.

In short, it is very important to understand the center, purchase guide and master some basic roasting skills when purchasing and making coffee. By understanding different grades, choosing fresh varieties that suit your taste needs, and mastering the appropriate manual or mechanized family-style small-batch coffee bean processing, we can improve our understanding and experience of coffee quality.
