Five storage conditions for teas

1. Sunlight

Sunlight can quickly degrade your teas by destroying Vitamin C in leaves, darkening tea liquid and bittering taste. So, if you want to enjoy them later you need to bear this in mind.

2. Temperature/Heat

Temperature is also a crucial factor that needs to be treated carefully. Experience tells us high air temperature can speed up the rate of deterioration by decreasing the nutrient content and results in bad taste. So, avoid placing it in the sun or lamplight or place near heat sources, like a stoves and ovens is necessary.

3. Moisture

Just like desiccant, tea absorbs water from the air easily. Especially for some teas undergone baking and drying process when producing such as “green tea” or white tea can easily go bad if allowed to become damp. So, tea leaves with higher level of water content is much more like a breeding ground for microbes which may cause mildew because water is an essential condition for microorganism activities.

4. Air

Exposure of the tea to air can be harmful to tea flavor as it increases the chances of absorbing moisture and odors. So, you’d better use the clean and airtight container to store them.

The good way of storing food in refrigerator to keep them fresh is also can be applied to tea storage. When doing this, you’d better pack them in sealed package first to avoid odor and moisture which can damage tea color and taste. At the same time, another thing you should keep in mind is that long preservation in refrigerator can downgrade tea quality as well, even if the rate is slow. So, you should consume them as fast as you can. Generally, Black tea can be stored well in dry conditions with temperature blew 5 degrees Celsius for more than 1 year.

Secondly, fill your vacuum flask with dry leaves (gently and slowly) as much as you can to expel air vacuum flask out then close it with a cork. Thirdly, cover the cork with white wax then sticky tape to seal it tightly. Generally, benefiting from relatively moderate temperature, teas in vacuum flask can maintain fresh for relatively long time.

4. Charcoal-Sealed method of storing black tea

Charcoal possesses the characteristic of absorbing moisture and so some people take advantage of this to store black tea. The dry charcoal needed to be wrapped in a piece of clean cloth and then put in tea container such as a lidded earthen jar. Thereafter, you should examine them and replace them with dry new charcoal regularly to keep inner as dry as possible.
Note: Charcoal is a black substance obtained by burning wood without much air.

5. Keep it in airtight ceramics Jar (clay pot)

There is another way of storing black tea you may be interested in. Firstly, prepare a small dry, clean clay pot with a small bag of lime powder inside. Secondly, put tea bags onto or around the small lime powder bag (which can soak up excessive water vapor) one by one until with no more room left. Thirdly, cover the pot with a bag of cotton as tightly as possible. To keep inner dry, the lime powders needed to be changed every one or two months.
