I tried the green tea with Japanese orange Mikan (also known as Citrus unshiu, Japanese Citrus or satsuma mandarin.
This tea is grown by the ancient Chagusaba method. It's a method where grasslands are grown around the tea field and supply mulch for the shrubs.
It is easy to prepare with no teapot required. You simply add the powder into hot or cold water. It was delicious hot and I think that it will also be great added to cold water in a thermos bottle to take to Zumba class.
You can order some for yourself here.
