How should tea be stored to maintain its stable quality?
Once a bag of tea is opened, it should be finished within 3 months to enjoy its freshness. Although tea is safe to consume even after being kept for a few years, its freshness diminishes over time. Tea must be tightly sealed and stored in ambient, dry conditions such as in the living room, away from humidity. Avoid storing tea in the kitchen or enclosed areas like cupboards or drawers as these places are damp. It is recommended to open tea bags on a sunny day or in an air-conditioned atmosphere to prevent moisture absorption, which can lead to deterioration within a few days, making the tea taste astringent or sour and weakening its fresh aroma.
