For optimal flavor, never reheat tea or coffee.
The proper storage of tea is necessary to optimize flavor from your tea. In How to Brew Tea we discussed proper brewing of tea and shared tips on optimizing flavor. Of course we also included how to store tea. Proper tea storage is essential for optimal flavor. If tea is not properly stored it will lose flavor. To properly store tea you want to prevent exposing tea to extreme heat or cold, light, moisture and air. Tea is best stored in an airtight non-plastic container. Ceramic, sealed wood or metal works best. Tea will readily absorb a plastic flavor. When storing tea do not place your tea near your spices or scented candles as it will absorb those flavors and odors as well. Keep it separate from other foods and at room temperature away from heat. Consider placing your tea storage container on a shelf in your kitchen cabinet. If possible do not choose a cabinet above your stove, oven or other heat source. Do not store tea in the refrigerator. A darkened or opaque container is best as it will prevent your tea being exposed to light.
If you use loose tea leaves you have many options. There are several styles of canisters and tea storage containers available. Some teas like those from Adagio Teas are delivered in tins which are fine for storage. Below are examples of canisters and storage containers for tea. Canisters are available in a wide array of designs so you can choose one that matches your decor. If you purchase tea bags you may store them in canisters or consider a tea storage box as shown below.
