Coffee "public beans and mother beans", which originated in Indonesia, is a gimmick aimed at tourists. Many people call coffee round beans "public beans" and flat beans "mother beans", but as far as botany is concerned, this is obviously eavesdropping.

Coffee belongs to the family Rubiaceae, whose flowers belong to "complete flowers", that is to say, "self-pollination". A flower itself has stamens and pistils, and there is no distinction between male and female plants or male and female flowers at all.

Coffee flower ovary has two ovules, because it is self-pollination, so the pollination rate is very high, usually two ovules will be pollinated successfully, and develop into coffee berries containing two seeds (flat beans); but a few have only a single ovule pollination, and develop into a single and round seed, so it is called "single bean", also called "round bean" (called pill bean in Japan).

What is round bean coffee (PB)?

Coffee is a kind of fruit, and the outer layer of coffee fruit has pulp (pectin layer), and the middle is usually composed of two seeds facing each other (just like the fruit we usually eat). The plane of the two seeds faces inward, and the round face faces the outer pulp. The round bean is a hereditary malformation. there is only one seed instead of two seeds in the fruit, which has no plane and has round faces on both sides.

The two coffee beans above are round beans on the right and normal coffee beans on the left. You can see that each side of the round beans is round, while the normal coffee beans are flat on one side.

Why are there round beans?

No one is sure, and so far there is not enough scientific research to explain the origin of round beans, and 5-10% of the seeds in the coffee fruit of each coffee tree are round beans.

How to screen out round beans?

Round beans can be found in every kind of coffee, or in any coffee-producing country. Coffee round beans are due to the fact that in the coffee processing process, it is entirely hand-picked to distinguish and screen these round beans.

Round beans are often found in Tanzania, Kenya and Brazil because these countries have special instruments and systems for screening round beans.

What's so special about round beans?

This part is controversial, some people think that round beans taste better, compared with the same batch of normal beans, round beans have a slightly brighter flavor and lower mellow thickness. However, this has never been proved. Making round beans is like brewing other ordinary beans, and when you enjoy coffee made from round beans, you must attribute the taste of the coffee to these selected special beans.

Therefore, if someone says to you in the future: the flavor of round beans grown in the same plant is different from that of flat beans, the flavor of round beans is better. All you have to do is laugh it off and listen!
