II. Classification of chestnut varieties

China has a great many chestnut varieties; according to statistics from the relevant departments, local varieties number more than 300. By production region, chestnuts are generally divided into two types, northern chestnuts and southern chestnuts. Northern chestnuts are mostly used for roasting and eating, while southern chestnuts are used for cooking.

1. Northern chestnut

It is mainly distributed in the Yanshan and Taihang Mountain areas of North China and their neighboring areas. This includes Hebei, Beijing, northern Henan, Shandong, parts of Shaanxi and Gansu, and northern Jiangsu. Its characteristics are a small fruit shape, with a single nut averaging about 10 grams; waxy flesh, with a sugar content as high as about 20%; low starch content and high protein content in the flesh; a relatively dark, glossy skin; a strong aroma, and a bitter skin that is easy to peel off. It is suitable for roasting and eating, and is called sugar-roasted chestnut.

2. Southern chestnut

It is mainly distributed in Jiangsu, Zhejiang, Anhui, Hubei, Hunan, and southern Henan. In this region, with its high temperatures and abundant rain, the chestnut nuts are large in shape, with a single nut averaging about 15 grams and reaching up to 25 grams at most, but with low sugar content and relatively high starch content, and flesh on the glutinous side; they are mostly used as cooking chestnuts. There are many chestnut varieties in both the north and south of China, and there are differences in the characteristics and traits of the southern and northern variety groups. Generally, the quality of the southern variety group is not as good as that of the northern varieties, and the flesh is on the glutinous side, suitable for stir-frying, and is also called cooking chestnut.

Hebei is rich in chestnut resources, and its export volume ranks first in the country. The Yanshan Mountain range areas such as Qianxi, Zunhua, and Xinglong are important chestnut export bases in China, and their product quality is excellent and renowned at home and abroad. Especially in Japan, they are called “Tianjin sweet chestnuts”, enjoying a long-standing reputation and being deeply loved by the Japanese people.
