To enjoy tea for a long time while keeping it fresh, proper storage methods are crucial. Many people wonder whether it’s better to use the freezer to prevent tea leaves from deteriorating. In this post, we’ll explore the best ways to store tea in general.

Is Storing Tea in the Freezer Effective?

Tea leaves are highly sensitive to oxidation and moisture, and their quality is greatly affected by how they are stored. Because of this sensitivity, storing tea in the freezer, where the humidity is low and the low temperature slows oxidation, is one option. In fact, storing unopened tea leaves in the freezer can prevent oxidation and preserve their aroma and flavor for a long time​​.

Why It’s Often Better Not to Use the Freezer at Home

When storing tea leaves at home, it’s often better not to use the freezer. This is because storing tea in the freezer can make it difficult to manage temperature changes, and condensation can damage the leaves. When you take the tea out of the freezer, a sudden change in temperature can cause condensation to form on the leaves, making them more likely to absorb moisture and deteriorate in quality.

Considering these risks, it’s generally recommended to store tea at room temperature at home, as this can lower the risk of deterioration and allow for more stable storage​​.

Tips for Preventing Tea Leaf Deterioration at Room Temperature

Here are the three most important points to remember when storing tea:

  1. Avoid Moisture
    It’s important to keep tea leaves dry. If stored in a humid environment, the leaves can absorb moisture, which not only diminishes their flavor but also increases the risk of mold. The basic rule is to store tea in airtight containers in a low-humidity location​​.
  2. Protect from Light and Air
    Exposure to light and air accelerates oxidation, causing the aroma and flavor of tea leaves to deteriorate. Use containers that block light and seal tightly to keep the tea fresh​.
  3. Temperature Control
    As much as possible, maintain a consistent storage temperature​.

Other Points to Consider

Many types of tea, such as Earl Grey, are scented with flavorings, like bergamot oil, to give the leaves their distinctive aroma. There are also teas flavored with peach, apple, and other scents. In the tea industry, this process is referred to as “scenting.” While scenting isn’t a bad thing, it’s important to store scented teas separately from other teas, as the aroma can transfer to nearby tea leaves. For example, if you store Earl Grey with deep-steamed green tea in the same container, the green tea might absorb the scent of Earl Grey. Therefore, it’s recommended to store scented teas separately from unscented ones whenever possible.

What’s the Best Place to Store Tea Leaves?

You might be thinking, “There’s no perfect place that meets all these conditions!” While it may be challenging to find a location that meets every criterion perfectly, try to find an environment that comes close. For instance, the place where you store your rice is often a good environment for storing tea as well. Another option could be inside a cupboard. Don’t be too anxious about it; just find a reasonably good spot to store your tea.
