Tea—like all agricultural goods—is a product of the seasons. In winter: hibernation. In spring: regrowth. In summer: reaping of spring's rewards. And in autumn: preparation for the solitude ahead and a transition towards sweeter, more comforting brews.
Green tea in particular is a product of the seasons. Crafted directly after harvesting—with minimal processing or intervention to change the flavor profile—green tea represents its terroir and a moment in time, preserved. Green teas generally do not age well and should be drunk as soon as possible. After all, there is always next year's tea.
