The shape and characteristics of coffee beans

Coffee beans are a common food and beverage ingredient with a unique aroma and taste. They are well-known for their shapes and characteristics. The following will introduce coffee beans from different angles.

Appearance

Coffee beans are usually flat and oval in shape, with slightly pointed ends. Their colors vary by species, and include yellow, red, green, and black. Ripe coffee beans have a smooth and shiny surface, while unripe or damaged ones may appear bumpy or spotted.

size

Coffee bean size also varies by variety. Generally speaking, larger sized coffee beans are used in most commercial production. These larger particles can be more easily sifted out by machines, and it is easier to control the temperature and time during processing.

However, not everyone likes larger beans. Small or medium-sized beans (also called "germ") are generally considered to have a stronger taste and aroma. They are also better suited for pour-over or other specialty brewing methods.

hardness

The hardness of coffee beans is one of the important factors that affect their roasting process and taste. Harder coffee beans usually take longer to fully roast, while softer ones are relatively easy to reach the desired degree.

In addition, hardness is also related to the amount of dust the coffee beans produce when ground. Softer coffee beans may break into fine particles during processing, resulting in a lot of dust and it may be difficult to control the extraction process.

Moisture content

Moisture content is another important parameter that directly affects the stability of coffee beans during processing and storage. Generally speaking, coffee cherries that are not treated or not dried sufficiently after fresh picking will retain a higher moisture content.

High moisture content can easily lead to problems such as mold and fermentation, and will reduce the quality and taste of coffee beans. Therefore, coffee beans usually need to be dried before processing to reduce the moisture content.

Summarize

The shape and characteristics of coffee beans have an important impact on their final quality and taste. Factors such as appearance, size, hardness and moisture content need to be properly controlled during planting, picking, processing and storage.

Understanding these characteristics can help us better choose coffee beans that suit our taste preferences, and better appreciate and enjoy the unique flavors of coffee from different types and origins.
