The top-notch of Japanese green teas, Hon Gyokuro (meaning "Jade Dew") is in a class of its own.   The young leaves are shade-grown for 3 weeks to increase caffeine and flavoring and later steamed and tightly rolled.  The result is a brilliant green color & ultimate fresh umami taste. Note: due to high caffeine level you will feel a pleasant, steady jolt more than any other green tea.
