Short story about Gunpowder Green Tea

This green tea owes its name to the fact that its leaves are rolled into the shape of little pinhead pellets that resemble gunpowder. These tea leaves stay fresher for longer than any other green tea due to their compressed form. Gunpowder tea has a higher caffeine content than most other green teas, allowing it to be used by athletes to improve general endurance.
The citrus character of lemon, combined with the grassy flavour of Green tea create a perfectly balanced drink.
