Grain Rain is the solar term of nourishing rain and steady growth. This tea follows that same philosophy: gentle support instead of intensity.
When schedules speed up, a three‑minute steep can mark a boundary between tasks: before email, between meetings, or after dinner when you want something warm without fuss.
No caffeine, no additives, no strong flavor profile—just a clean cup that fits daily routines.
