According to a proverb in Hengchun, “Hengchun black bean is not frightened by wind.”
This is the experience gained by farmer when planting beans since ancient time.
The downhill wind blows strongly to the Manzhou area. The planted native species of small black beans can sprout and stand in the strong wind. Their growth period is affected by the wind damage. Therefore, the plant is shorter. To propagate, black beans will insert all the nutrients into the seed, therefore the Manzhou black beans with smaller seeds are rich not only in flavor, but also in nutrition.
Black beans are commonly known as “Wu dou” are mainly consisted of two kinds of beans. These are green kernel black beans and yellow kernel black beans. As the names suggest, the bean color is black, while the kernel color is green and yellow respectively. Green kernel black beans (including Pingtung green kernel black beans and Tainan No. 3) are the most nutritious. They contain an extremely high content of protein, vitamins, iron, amino acids, carbohydrates, etc.
