Peaberry, commonly known as "male bean" in Chinese, is a variety of coffee bean, also called caracoli in English. In botanical terms, peaberry can actually be considered a defect. The reasons for this defect typically include insect damage to coffee fruits before they ripen, the coffee tree suffering from prolonged drought or nutritional imbalance, or coffee beans growing at the end branches of coffee trees.

Coffee beans are the fruit of the coffee tree. Under normal circumstances, a single fruit contains two coffee beans, known as Type I, commonly referred to as flat beans. However, due to the aforementioned factors, some fruits mature with only a single bean. This oval-shaped single bean is commonly known as peaberry, or Type II. Compared to Type I, Type II is sometimes colloquially called "female bean" in Chinese, but in reality, these are just differences in coffee bean growth patterns, not gender differences. This Chinese colloquialism can easily mislead coffee enthusiasts.

Some people are fascinated by peaberries, but speaking of which, we've only heard of flowers having male and female distinctions. Coffee beans are seeds of the coffee tree—how could seeds possibly have male and female differences? Could it be that male bean seeds grow into male trees, while female beans grow into female trees? Of course, this speculation is nonsense. Coffee trees have no gender distinctions; each coffee flower possesses both male and female organs simultaneously. Coffee beans have no male or female classification—what you've heard is purely a marketing gimmick created by merchants to sell products.

The correct terminology is "Flat Beans" and "Peaberry." Under normal circumstances, a coffee berry contains two flat beans (seeds) divided in half, but in rare cases, the internal seeds don't split, instead presenting as a complete oval-shaped single peaberry. Generally, peaberry production is about 1/50 of flat bean production.

Some coffee drinkers believe that peaberries have more intense aroma because normal coffee beans should have two seeds, but peaberry coffee has one underdeveloped seed, making the other exceptionally large. Because it receives double the nutrients, its taste is better than flat bean coffee. At the same time, due to its rarity, it is sometimes sold at inflated prices. In contrast, in different coffee-producing regions, these beans are sometimes classified as defective beans and discarded.

Currently, peaberry varieties appearing on the market include famous examples like Kona coffee beans, where about 5% of Kona coffee beans grown in Hawaii are peaberry. Additionally, about 5-10% of Tanzania Peaberry coffee fruits also exhibit the peaberry form, and these beans are particularly small.

In fact, whether peaberries actually taste better remains inconclusive. The reason is that different coffee bean varieties produce peaberries with varying flavors. Additionally, the factors that create the peaberry form might be influenced by human intervention, making the pricing of peaberry beans still questionable.

Knowledge point: Coffee takes approximately five years from cultivation to fruit production. During this process, steps including flowering, fruiting, harvesting, processing, storage, and sales continue until we receive the raw coffee beans in the terminal market.
