Buckwheat tea is often used in restaurants. But bitter buckwheat tea can be divided into black bitter buckwheat tea and yellow bitter buckwheat tea.

Tartary buckwheat, as long as it grows in the alpine region above the altitude of 1000 meters, needs relatively low conditions, and the yield per mu is about 500 kilograms. The nutritional value is relatively low.

Black tartary buckwheat tea needs to grow in the alpine region above 2400 meters above sea level. Planting conditions are quite harsh. They can plant about 100 kg per mu. The nutritional value is much higher than that of tartary buckwheat.

Yellow tartary buckwheat tea is cheap, but its nutritional value is not high. It is best to use black tartary buckwheat tea in restaurants, which can not only ensure customers to drink safely, but also remove heat for customers, promote digestion and indirectly attract business for hotels.
