Tea doesn't spoil in the sense that it becomes dangerous to drink, but it does lose some of its freshness, flavor, complexity, sweetness, and even antioxidants as it ages.
You may be wondering, since the refrigerator keeps other foods fresh, why tea leaves cannot be stored in the refrigerator.
Tea is hygroscopic, which means it can absorb moisture from the air, according to Tea Epicure.
Because tea leaves release their aromas and flavors upon contact with water, it is essential to keep the leaves dry until you are ready to brew them.
Eco Cha notes that refrigerators, despite being cool and dark, are not ideal for storing tea due to their high humidity levels.
Another reason tea shouldn't be stored in the fridge is because it picks up odors and flavors from other foods, as suggested by Valley Brook Tea.
Your tea's delicate flavor could be ruined if you store it in the fridge, which is home to everything from onions to (often uncovered) leftover pizza.
Whether you're storing Da Hong Pao tea ($1,400 per gram) or your favorite Earl Grey, keep tea leaves in an airtight container away from heat, moisture, and light.
