How will we store our teas?

Tea is one of the most popular beverages in both East and West. In order to keep this tradition alive, it needs proper storage methods that can preserve its flavor without losing any appeal or taste-quality ascribed by growers who produce high quality leaves desired when brewing an excellent cup o’joe!Stores tea in a way that protects both the consumer and economic benefits for producers.The effects of external storage environment conditions on tea quality and transformation during its lifetime can be explained in this section. Storage methods are also mentioned, along with their impact on your favorite beverage!

1. Effects of storage environmental conditions on tea quality Temperature

The temperature plays a more important role in determining the quality of tea than oxygen and moisture.As ambient temperatures increase, active ingredients within teas gradually decrease; this change includes aromatic substances like flavorings or tannins that give it its distinct taste profile as well vitamin C,amino acids and tea polyphenols which contribute various properties such aroma-WELL BEING ONE OF THEM! Cold storage (below than 10℃)is essential for preserving these beneficial changes by limiting deteriorative processes associated with increased heat exposure.


There are many factors that determine the quality of your tea, but humidity is one important factor. The correct level of moisture can have a huge impact on how tasty and aromatic it will be when you drink.Humidity refers to the relative humidity of the air in the storage environment,and also the moisture content of tea itself.The presence of mold and humidity are closely associated with each other. Dry tea is extremely hygroscopic - it will absorb moisture from the air around it if there's too much for its own good!As moisture content increases in dry teas and different chemical reactions are accelerated due to increased humidity around them; this is perfect for mold growth!The higher the moisture content, the more pronounced is diffusion and interaction between substances. As a result of this mold will propagate faster in your tea leaves as well as make it easier for other unwanted elements to grow within them too! Be sure that the tea leaves' moisture level never exceed 6% or else those pesky fungi might take over completely--the ambient humidity should stay below 50%.


When tea is exposed to light, it speeds up the oxidation process of pigments and lipids which leads not only in a decline for its preservation but also can cause major changes on other aspects like flavor profile. Light-sensitive compounds such as polyphenols,amine acids and alkaloidsare degraded faster than before due this degradation's impactful effect upon coloration/flavoring qualities along with aromatics desirable trait.


As dry tea ingredients are able to auto-oxidize with the presence of oxygen, they can be automatically oxidized and decomposed during storage.The aldehydes, hydrazines, phenols, etc., are easily oxidized by the molecular oxygen in the air to form oxides.It's no secret that tea leaves are subject to oxidation when exposed in air. Tea polyphenols, vitamin C and aroma components are easily oxidized by molecular oxygen in air to form unstable compounds. Most of the tea products after oxidation are unfavorable,but the post-ripening dark tea is the only type of beverage that can be stored after oxidation and still maintain its quality.

2. Changes in the composition of tea during storage


The change in the polyphenols during storage is mainly non-enzymatic auto-oxidation, which means that they're undergoing oxidation at certain temperatures and humidity. Though this type of reaction isn't as intense compared to what happens through enzymes oxidation.The long-term storage of tea can lead to significant deterioration in quality. especially for teas with high moisture content and at relatively high temperatures, where polyphenol reduction is more severe than it would be otherwise due largely from this type oxidation process alone.


The green in your tea leaves is what makes it shine, but the pigment that gives color to these drinks may be more unstable than you think. Chlorophyll accounts for 0.7% -1.2% of the dry tea. Under light and heat conditions with exposure to sunlight or heating up too much can cause them turn brown due a reaction between replacement reactions where there's been decomposition occurs which makes magnesium removal reaction become stronger as moisture content increases causing yellowish-brown pheophytin when 70%-plus Convertion Rate of chlorophyll happens.

Amino acids

The content of amino acids is reduced over time. On the one hand, they can react with polyphenols and sugars to form polymers.The quality of your tea can suffer if the tea storage time extends. Amino acids are susceptible to degradation when stored for too long and will cause oxidation, which reduces flavor complexity in general as well as other tea quality.

Vitamin C

The nutritional value of tea is reduced during storage due to the conversion from vitamin C into oxidized forms. This causes it no longer have that bright, fresh taste and appearance you want in your delicious cups o’joe! As well as this browning process happening with more than 15% decreased levels on Vitamin C, the tea quality deteriorates obviously.

Aromatic volatiles

The storage process for tea leaves reduces the amount of aroma components, which results in a stale smell and taste. If you store your loose leaf teas improperly they can even emit an unpleasant odor to affirm this fact!

3. Tea storage

Tea is a delicious beverage that has been enjoyed around the world for centuries. Studies show you can extend its shelf life by storing it correctly, but there are many factors on correct storage and transportation conditions involved in doing so!Though there are different types of storage for tea, they're all stored away from light and high temperatures to keep them lasting longer. Unlike most other types of tea that is best for low temperature storage, white and dark teas can be stored at room temperature.

Store tea in a dry environment

Keep your tea fresh in a dry container by keeping it out of direct sunlight and away from moisture. Moisture can reduce the lifespan, mold may even grow in damp places!

Keep tea away from sunlight

To ensure that your tea stays fresh, always keep it in an airtight container. Don't use glass jars because they're not able to block out all light which will cause the substances of oxidation on its surface,which will weaken tea fragrance and change tea quality. Store your tea away from direct sunlight in dark or cool place for best results!

Keep tea sealed from the air

When storing tea, make sure there's as little air in the pouch or bag before closing it up. If you have a vacuum sealer and are using those bags for long-term storage of your favorite brews then be aware that they'll last quite awhile if kept sealed between uses!If you vacuum up some long, un-curled and unwieldy leaves they might get crunched under the weight. To prevent this from happening make sure to seal your bag between uses as well as removing any excess air before weighings begin!

Store green tea in the refrigerator

If you have a vacuum sealer, then go ahead and thoroughly protect your tea in an environment with little or no moisture,and store it in the refrigerator on a colder setting, or the freezer. The controversy surrounding improperly sealed tea bags stored in the freezer is that they will be damaged. In addition, it's best to store your loose leaf shipment with an appropriate amount as opening up this package too often can affect its quality and aroma over time!


Tea quality deterioration is generally due to various content changes during storage, such as tea polyphenol,amino acids,vitamin C and lipids as well as pigment,which lead to the reduction of aroma and original unique taste.The quality of your tea will depend on many factors, including moisture content and storage temperature and oxygen level as well as light.The quality of tea depends on many factors, including how it's stored. The packaging materials and microorganisms can also affect the taste or appearance over time.To ensure the long life of your favorite brew, it’s important that you take into consideration all factors when storing and preserving them.The deterioration of green tea quality is greatest when stored in low temperatures, with exposure to bright light and high levels oxygen. New packaging technology can help prolong its storage stability by keeping out these three things!
