Detailed analysis of the specific changes in the ripening process of coffee beans by diagrams of the growth and ripening process of coffee beans
It takes about 8-9 months (32-36 weeks) for coffee to blossom to ripen. Today, Chongqing Beresta Coffee training School is here to share with friends the whole process of coffee bean growth and ripening.
[tiny stage] (the first 8 weeks) Arabica coffee begins to divide eight weeks after flowering and fertilization.
[preemptive site stage] (8-12 weeks) the vesicle cavity (with ovary) begins to expand rapidly with the expansion of the seed coat, and the space for expansion will be the endosperm, that is, the growth space of coffee beans.
The size of the expansion depends to some extent on the moisture content in the soil, and if the soil is dry (during the dry season), the seed coat expansion will be smaller and the final coffee beans will be smaller.
[endosperm development stage] (12-20 weeks) endosperm began to develop, consuming and absorbing seed coat.
[endosperm development stage] the endosperm continues to grow until the seed coat is completely absorbed, leaving a thin layer of seed coat that will cover the endosperm, also known as the silver coat; at this stage, most of the endosperm material is in a gelatinous state, and will continue to grow and develop in the next few months, forming the dry matter tissue of coffee beans.
[adult] (20-32 weeks) the pericarp and pulp of coffee fruit will continue to grow, and the endosperm will absorb 70% of the total energy of photosynthesis for its own growth.
[ripening stage] (32-36 weeks) when the coffee fruit grows to adult size, after a month or so, the coffee fruit begins its ripening and discoloration process, from green to yellow to red
