How do you store your tea leaves? Have you ever taken out tea leaves that have been sitting for a long time and found that the flavor isn`t as rich and full-bodied as before, or even developed a sour or bitter taste? Well, that could be a problem with how you`re storing your tea leaves! Follow along as we tell you the correct tea leaf preservation methods and precautions to ensure that your precious tea maintains its aromatic flavor at all times.
What to Consider When Storing Tea Leaves? 3 Major Factors that Affect Tea Leaf Quality
If you want to properly store tea leaves, you first need to know what factors can affect the quality and flavor of tea leaves. Therefore, below we list the 3 main reasons for tea leaves losing flavor, so you can understand the influencing factors that need attention when storing tea leaves.
Oxygen: Oxygen is the primary factor affecting the preservation of tea leaves. Prolonged exposure to air can cause tea leaves to oxidize easily, resulting in changes in the color of the leaves, as well as the color and aroma of the brewed tea. Therefore, most tea leaves are packaged in vacuum-sealed bags.
Light (and Heat): Light and heat are also factors that affect the quality of tea leaves. Exposure to light can cause the chlorophyll in tea leaves to fade, affecting the color of the brewed tea; high temperatures can also cause the loss of aroma in tea leaves. Therefore, the correct way to store tea leaves is to avoid direct sunlight and store them in a cool, shaded place.
Moisture: Dry tea leaves can absorb moisture and odors from their surroundings, increasing the moisture content of the leaves. This not only promotes oxidation but also affects the flavor, aroma, and color of the brewed tea.
Correct Tea Leaf Preservation Methods │ Significant Differences Before and After Opening
For food that cannot be consumed immediately or needs to be stored for a long time, we are accustomed to refrigerating it in the refrigerator. Can tea leaves be stored this way too? Generally speaking, unless you have a dedicated refrigerator for tea, it is not recommended to store tea leaves in the refrigerator. If you must store them there, only unopened tea leaves are suitable. Below, we`ll tell you the correct way to store tea leaves before and after opening, so you no longer drink tea with a stale taste.
Before Opening: Before opening, tea leaves should be stored in a cool, ventilated, dry, and shaded place. If your tea leaves are green tea, light oolong tea, or Oriental Beauty, they can also be stored in the refrigerator under special circumstances. However, it is important to ensure that the tea leaves are completely sealed before placing them in the refrigerator. After removing them from the refrigerator, allow the tea leaves to return to room temperature before opening to prevent them from absorbing too much moisture during the thawing process, which could affect their quality.
After Opening: Once opened, tea leaves easily absorb odors from other foods in the refrigerator, and the temperature difference when removing them from the refrigerator can cause moisture to condense on the surface of the tea leaves or be absorbed by them, resulting in changes in the tea`s flavor. Therefore, after opening, tea leaves should only be stored at room temperature, and attention should be paid to factors such as light and temperature in the storage environment. Store them in a cool, dry, and shaded place, and try to squeeze out the air from the packaging. Moreover, it`s best to consume them as soon as possible.
Tea Leaf Storage Common Q&A
So, do tea leaves go bad? Can you still drink tea if the color has changed? Finally, Teascape has compiled 5 common questions about tea leaf storage and answered them one by one, so you can fully understand all the ins and outs of tea leaf storage.
Q1: Do tea leaves go bad?
Tea leaves are considered truly spoiled only when they mold. However, with proper storage in a dry, ventilated, and cool place, it`s less likely for microbes to grow and cause mold. When tea leaves change color due to oxidation, such as when light oolong tea leaves turn from dark green to brown, it may affect the taste but doesn`t mean the tea leaves have gone bad!
Q2: Can you still drink tea if the leaves are yellowish?
As long as tea leaves haven`t molded, they are safe to drink. Apart from naturally yellow tea leaves, types like green tea and light oolong tea may turn yellow due to the chlorophyll in the leaves fading from exposure to light. While discolored tea leaves are still drinkable, their flavor might not be as good as before.
Q3: Do different types of tea require different storage methods?
The basic principle of tea leaf storage is to keep them in a ventilated, dry, and cool place. However, depending on the type of tea, there are specific factors to consider. For example, green tea, which undergoes minimal fermentation, is more susceptible to environmental factors and is best consumed soon after opening. On the other hand, black tea and heavily fermented oolong tea should be stored in a low-humidity environment, ideally below 80% relative humidity.
Q4: What type of container is best for storing tea leaves?
Metal containers (such as stainless steel, aluminum, or tin) are light-resistant, durable, and suitable for most types of tea storage.
Q5: What can you do if tea leaves become stale (oxidized)?
If tea leaves have oxidized and become stale due to prolonged storage, you can prepare a clean electric rice cooker, line it with white paper (preferably single-ply), preheat the rice cooker, and stir-fry the tea leaves with a metal spoon until they release a nutty aroma. Once done, your tea leaves are refreshed!
