As is well known, Pu-erh tea becomes more fragrant with age, thanks to the continuous transformation of this Yunnan large-leaf tea during storage. But what conditions actually promote this transformation? Today, let’s discuss how to store Pu-erh tea properly.

Pu-erh tea isn’t overly picky about storage locations—whether in a living room or a dedicated space—as long as it’s kept away from direct sunlight, in a cool, well-ventilated area, and far from pollutants or strong-smelling items like soap, mosquito coils, or camphor.

1. Circulating Air

Tea contains many microorganisms, and circulating air provides ample oxygen, aiding their growth and accelerating the tea’s transformation. However, placing Pu-erh tea on a balcony may disperse its aroma, resulting in a bland taste when brewed. Thus, moderate air circulation is ideal, but avoid windy spots. Also, ensure the surrounding environment is free of odors that could alter the tea’s natural flavor.

2. Stable Temperature

The storage temperature for Pu-erh tea should match the ambient room temperature, ideally between 20–30°C. Excessive heat can speed up fermentation, leading to sourness. Note that tea transforms faster in spring, summer, and autumn than in winter. Store it away from direct sunlight in a cool place.

3. Moderate Humidity

Pu-erh tea storage is categorized into "dry" and "wet" aging. Today, "dry aging" is more common, referring to storage in a dry environment—avoid dampness. However, overly dry conditions slow down the aging process, so some humidity is beneficial. In arid environments, place a small cup of water nearby to slightly increase moisture.

Excessive humidity, though, can cause rapid changes, often leading to mold, rendering the tea undrinkable. Control humidity carefully, keeping the annual average below 75%. Coastal areas with high humidity during rainy seasons should ensure proper ventilation to reduce moisture. Proper storage enhances fermentation, allowing the tea to mature beautifully and increase in value over time.

4. Suitable Storage Containers

Ceramic jars are ideal for storage. For larger quantities, use ceramic urns or vats. Their breathable nature makes them perfect for Pu-erh tea. The container opening need not be sealed—just cover it with kraft paper to keep dust out. Turn the tea every 3–5 months for even aging.
