The Collector’s Guide: How to Age Puerh Tea at Home

If you’ve recently purchased a high-quality Puerh cake from Jiangnan Sourcing, you are now the guardian of a living organism. Puerh tea undergoes natural fermentation over years and decades, transforming from a sharp, astringent brew into a smooth, earthy elixir.

However, "aging" is not the same as "forgetting." To ensure your tea evolves beautifully, you must control its environment. Here is how to create a professional-grade "Tea Cellar" at home.

1. The Golden Rule: Let It Breathe (But Not Too Much)

Unlike Green tea, which requires an airtight vacuum seal, Puerh needs a small amount of oxygen to allow the natural micro-organisms to continue their work.

• The Vessel: Use a Zisha (Purple Clay) Tea Caddy. The micro-pores in Yixing clay allow for a "slow-breathing" environment that stabilizes the tea.

• Avoid Plastic: Never store Puerh in plastic bags or airtight Tupperware for long periods, as this can lead to "stale" tea or even mold.

2. Temperature and Humidity (The "Sweet Spot")

The environment is the most critical factor in aging.

• Humidity: Aim for 60% to 70% relative humidity. If it’s too dry (under 50%), the fermentation stops and the tea "dies." If it’s too wet (over 80%), you risk mold.

• Temperature: Keep your tea in a stable environment between 20°C and 30°C.

• Pro Tip: If you live in a very dry climate, placing a small [hygrometer] inside your storage cabinet is essential for monitoring these levels.

3. Protect Against the "Tea Killers"

Puerh is highly absorbent. If you store it near your spice rack or in a damp basement, your tea will taste like cumin or wet cardboard within weeks.

• Odors: Keep tea away from kitchens, perfumes, and cleaning supplies.

• Light: UV light degrades the tea. Always use opaque Ceramic or Clay Caddies rather than clear glass jars.

4. To "Break" or "Keep Whole"?

Should you break your Puerh cake into pieces or leave it as a disk?

• For Long-Term Aging: Keep the cake whole in its original paper wrapper.

• For Daily Drinking: Break a portion of the cake and place it in a Yixing Tea Caddy for 2 weeks before drinking. This is called "waking up the tea," allowing it to adjust to the air and unlock its aroma.

5. Periodic "Health Checks"

Every few months, open your storage containers.

• Scent: It should smell clean, woody, or slightly sweet.

• Sight: Check for any fuzzy white or green spots (mold). Note: "Tea Frost" (tiny white crystals) is a natural occurrence of oils and is safe, but fuzzy mold is not.

Start Your Aging Journey

The best time to start aging Puerh was ten years ago; the second best time is today. By investing in a high-quality Zisha Tea Caddy, you are giving your tea the best possible home to mature.
