Karigane tea is made from the stems and veins of Gyokuro and Sencha which are rendered brown by roasting. The popularity of our 'Kaori Fumi' stems from its accessible nutty and mesquite taste. The roasting process lowers the caffeine content of the tea leaves. So if you are looking for a low-caffeine green tea, this is a wonderful choice. In the summer please boil the leaves 30 seconds and refrigerate them before adding some ice cubes. This will make a delicious and amazingly refreshing beverage. A good tea for those hot and tiring summer days.
