1. Sencha (Green tea)
Why now
- The everyday Japanese green: bright, grassy and easy to keep by the keyboard.
- Moderate caffeine with L-theanine — the calm-alertness combination.
- Several short steeps from the same leaves carry a whole writing session.
How to brew
If you don't have it
Any everyday green works — just keep the water below boiling.
Tea fact
Sencha was invented in 1738 by Nagatani Soen, who spent 15 years perfecting a steaming method so ordinary people could enjoy quality green tea; it now represents about half of all tea produced in Japan.
