How to Make Tea Last
My tea audiences across the country always want to know how long tea lasts and how it should be stored. Tea drinkers have always tried to keep their precious tea fresh as long as possible. Colonists at the time of the Boston Tea Party sometimes used wooden tea caddies like their British cousins. These tight coffers kept expensive teas securely locked away from both the elements and light-fingered household staff.
The enemies of tea are humidity, air and light. It is always best to transfer both loose tea and tea bags from a cardboard or paper container into an air-tight container. Tins and caddies with tight-fitting lids are best as they will keep out other smells and humidity. Glass jars on open shelves are not ideal for storage as light can damage the leaves and reduce the quality. However, glass jars may be stored in dark cupboards away from light. With the exception of Japanese Matcha, most teas should not be kept in a refrigerator.
