Why Airtight Glass Jars Are Great For Tea & Dried Food Storage

When it comes to storage, tea leaves can be grouped with other dried foods. This include dried fruits such as mango slices, goji berries and jujubes (red dates) as well as dried meat.

Why Tea & Food Is Dried for Conservation?

In fact, drying is one of the oldest methods of preserving food and it’s part of different tea processing methods for thousands of years. From a tea production point of view, drying simply can be seen as extracting water content from the leaves.

Different types of tea undergo different levels of water extraction. Green tea is only shortly air dried and pan-fried in China, which is why it’s water content remains high and the color of the leaves is still green. In contract, the water content in black tea is extracted to a minimal amount, which is why the color turns black.

The less water content the leaves have the longer the taste and aroma can be preserved. This is why green tea should be preferably consumed within the year of production, while black tea can be kept at least for two years. However, when stored in an airtight jar and stored in a fridge, green tea be preserved for up to 2 years.

Even black tea can decay fast if you expose the leaves to humidity and oxygen. The dry leaves act as a magnet that will absorb liquids from the air. Therefore, airtight glass jars can come in handy as well for black teas to keep the leaves dry.

Glass jars have the following benefits:

  • Airtight jars can seal the content away from humidity and air. This makes them also suitable for storage in the fridge, which is highly recommended for green tea.
  • Protects the tea from bad odours. Store tea unsealed in the kitchen or fridge and they'll easily absorb the smell of food and spices. Airtight jars will prevent this from happening.
  • Glass is smell free and therefore won't affect the taste of tea and food.
  • They look great and fit in almost any kind of kitchen decor.

Because of the above benefits, glass tea jars are highly popular among tea users. However, there’s also one major disadvantage that you should be aware of:

  • Glass material doesn’t protect the content from light and heat. Therefore, glass jars should preferably be stored inside a cabinet or fridge.

How Much Tea Can Fit?

How much can fit inside a jar really depends on what you want to store in it. Even if you plan to store tea, tightly rolled teas can fit up to 3 times as much compared to a loosely rolled tea. In the video below we demonstrate this with a Tieguanyin (tightly rolled), Dahongpao (loosely rolled) and dried Jujube fruit slices using this jar.

Why You Should Fill Up Jars as Much as Possible

Even though the air is kept outside, there's always some room left inside the jar that contains some oxygen. To keep this to a minimum amount, it's better to store as much as tea as possible in the jar to leave less room for air.

Air tight mason jars are ideal for storage, due to the fact that they are impermeable to oxygen and they are not affected by residual humidity and most importantly they are inert to temperature fluctuations.

Can the teas be kept in their original Teasenz bags/packaging and just reseal the ziplock. ( and then keep in the fridge) Or is it best to transfer the tea to a glass jar, maybe to dark glass jar with a tight seal?

Our original aluminium bags/pouches are definitely suitable to keep the tea. The re-sealable zip closure keeps air and humidity away, and at the same time no sunlight can get through. The fridge is a tricky environment for teas. Most teas such as dark oolong, black, pu erh, aged white tea can be stored just at room temperature. With fresh green teas, light oolongs and some fresh white teas, you consider storing them in the freezer.
