How to judge the ripeness of coffee beans

Coffee is one of the most popular drinks in the world, and a soybean milk machine can not only be used to make delicious soybean milk, but also to crush coffee beans. However, before using a soybean milk machine to crush coffee beans, we need to first determine the ripeness of the coffee beans. Here are some common methods to determine whether the coffee beans are fully ripe.

Appearance Color

The first method is to judge the degree of roasting by observing the color of the coffee beans. Normally, untreated and unroasted fresh coffee cherries will appear dark green or indigo. As the cherries gradually mature into roasting, the color will gradually change to different stages such as yellow-brown, chestnut brown, chocolate brown, etc. When the cherries are completely dark brown, it means that they have reached the ideal medium to deep caramelization level.

odor

In addition to the appearance and color, the smell of coffee beans is also an important indicator of their maturity. Untreated fresh coffee berries usually emit a grassy aroma, and as the berries gradually mature during the roasting process, the aroma will gradually change to different flavors such as burnt, chocolate, and nuts. When you smell a strong coffee aroma, it means that it has reached the ideal medium to deep caramelization level.

Touch

In addition to appearance and smell, we can also judge the ripeness of coffee beans by touching them. Untreated and unroasted fresh coffee beans usually have a high moisture content and feel moist and brittle when rubbed in the hands. As the fruit gradually matures and roasts, the moisture content decreases and forms an internal cavity structure, making the coffee beans harder and less likely to break when rubbed in the hands. When you feel a hard and stable texture, it means that it has reached the ideal medium to deep caramelization level.

Fragmentation

The last method is to judge the ripeness of coffee beans by observing the degree of crushing. Unprocessed and unroasted fresh coffee beans are usually easy to crush, and as the fruit gradually matures and roasts, the coffee beans will become harder and less likely to crush. When using a soymilk machine to crush coffee beans, if you find it difficult to crush them completely, it means that they have reached the ideal medium to dark caramelization level.

In summary, observing the color, smelling, feeling, and checking the degree of crushing can help us determine whether the coffee beans are fully mature. Of course, before using the soymilk machine, make sure you have stored and preserved the coffee properly to ensure the best taste and quality.
