100% Sencha green tea from Shizuoka, Japan.
Most of the teabags served in restaurants or hotels are low cost suqare tea bags. Square teabags are packed with the lowest quality tea dust, which is the unwanted part after the green tea leaves processing. For real green tea taste, loose leaf tea is the best, or pyramid teabag is a good option too.
For restaurants or hotels who serve green tea in tea pot, this is a good candidate for you.
