Coffee beans: the source of a fragrant crop

Coffee beans are an intoxicating crop that not only brings us delicious coffee, but also has a rich cultural and historical background. This article will focus on coffee beans, explore their growth, processing and roasting process, and introduce some interesting knowledge about coffee.

1. Coffee bean growth process

The coffee tree is a tropical plant that is mainly distributed in areas near the equator. It needs plenty of sunshine, moderate rainfall and stable temperatures to thrive. It takes about three to five years from seed to mature fruit.

When the fruit is ripe, the outer skin will turn red or yellow and have a strong and fragrant aroma. At this time, the fruit can be picked.

2. Coffee bean processing

After being picked, the coffee cherries are processed through peeling, fermentation, washing and other steps. First, the outer layer of the coffee cherries is removed to reveal the coffee beans inside.

Next, the coffee beans need to be fermented. This process helps remove the pulp residue and enhances the flavor of the coffee beans. The fermentation time usually takes 24 to 48 hours.

After fermentation, the coffee beans need to be washed to remove residues and impurities. The washed coffee beans will be dried and enter the next stage - roasting.

3. Coffee bean roasting process

Roasting is a critical step in transforming green coffee beans into tasty, aromatic particles ready for brewing. Different degrees of roasting produce different taste and flavor characteristics.

Light roasting is generally carried out at around 180°C, at which time the coffee beans retain more original flavor and floral aroma; medium roasting is carried out at around 200°C, making the flavor more balanced; deep roasting is carried out at above 220°C, producing a rich and bitter taste.

After roasting, the coffee beans need to be cooled, graded and packaged to preserve their freshness and quality.
