Difference in nutritional value: Black buckwheat is known as "black pearl", its rutin content is 3~5 times that of yellow buckwheat, and other nutritional values are higher than that of yellow buckwheat.

From the price point of view, black buckwheat has low yield and high nutritional value, and its price is higher than that of yellow buckwheat.

On the whole, the efficacy of tartary buckwheat tea made of black tartary buckwheat is naturally better than that of yellow tartary buckwheat tea, and it is precisely because of its nutritional value and cost that the price of black tartary buckwheat tea is higher than that of yellow tartary buckwheat tea.

I hope I can help you and adopt it.
