Should Ripe Tea Be Aged? Resting Ripe Pu'er
Customers often ask us, "Does ripe tea need aging too?" The answer is that it doesn't have to be aged, but resting it will give it a different character. Ripe tea has already gone a long way in its transformation at the factory, so resting it at home is more like "finishing" and "polishing."
Ripe Tea Has Already Been Through One Round of Transformation
The key to ripe pu'er is wodui: sun-dried maocha is watered and heaped up to ferment under the action of microbes, heat, and moisture, usually for 30–45 days, with several turnings along the way. Research measurements show that from maocha to finished ripe tea, tea polyphenols drop by nearly 60% and theabrownin increases greatly, which is why ripe tea has a deep red liquor and a mellow taste. The wodui process is covered in Wodui: Where Ripe Pu'er Comes From, and the drying and resting after unpiling in After the Pile.
So ripe tea is "ready to drink" as soon as it leaves the factory, with no need to wait.
The Pile Taste in New Ripe Tea
Ripe tea that hasn't been out of the factory long often has a stuffy smell like damp straw or something fermented, which the tea world calls "pile taste" (duiwei), left over from wodui. How strong it is depends on the fermentation level and on how the tea was dried and spread out after unpiling. This aroma term is covered in Terms: Pile Taste, Nuo Aroma, Sweet Aroma, Caramel.
How long does the pile taste in new ripe tea take to fade? A common view in the tea world: kept somewhere dry and ventilated, a light pile taste fades within a few months, and most fade noticeably within 1–3 years. Teas with heavier fermentation, or that weren't properly spread out after unpiling, may take longer. Rinsing an extra time when brewing and pouring off the first infusion quickly also greatly reduces the pile taste.
How Ripe Tea Changes in Storage
| Storage time (reference) | Aroma | Taste | Liquor |
|---|---|---|---|
| New to 1 year | More noticeable pile taste | Mellow, sometimes a little stuffy | Deep red |
| 1–3 years | Pile taste fades, sweet and nuo aromas emerge | Smoother, cleaner | Deep red and bright |
| 3–5 years | Steady sweet aroma, a touch of aged notes | Silky, high sweetness | Bright red |
| 10+ years | Aged, woody, jujube, and herbal notes | Mellow and lingering | Deep red and clear |
Researchers have also tracked ripe tea of different ages: one study using 7572 ripe tea compared the aroma makeup of tea stored 1–9 years and found the proportions of different aroma compounds changed regularly with age; another compared ripe tea stored 3, 8, and 13 years and saw early floral and fruity aromas weaken while aged aroma compounds increased. The direction matches tea drinkers' experience: time makes ripe tea cleaner and more settled.
How Many Years Is Ripe Tea at Its Best?
There's no standard answer; it depends on your taste:
- People who like a clean, sweet tea with no pile taste often say ripe tea at 3–5 years is smoothest.
- People who like aged, herbal, and woody notes can wait 10 years or more.
- People who don't mind a little pile taste and like a deep red, heavy tea will enjoy new ripe tea just fine.
How Resting Ripe Tea Differs from Aging Raw Tea
- Degree of change: raw tea goes all the way from bitter, astringent, and brisk to mellow and aged, a big change; ripe tea is already mellow, and resting mainly clears the pile taste and rounds out the mouthfeel, a smaller change.
- Whether to wait: raw tea raises the question of a "drinking window"; ripe tea is ready to drink once made.
- Storage conditions: both dislike damp and odors. Ripe tea has been through wodui, and it's just as sensitive to humidity; keeping relative humidity below 70% is safest. See Temperature and Humidity for Storing Pu'er.
- Keep them apart: ripe tea's pile taste can transfer to raw tea, so it's best to keep them in different cabinets. The reasons are in How Tea Absorbs and Transfers Odors.
Storing Ripe Tea at Home
- Keep the original cotton paper and packaging, and put it in a clean, odor-free cardboard box or tea cabinet.
- Raise it off the floor and away from walls, and keep it out of the kitchen and bathroom.
- If new ripe tea has a strong pile taste, open the outer box and let it sit somewhere ventilated for a while before putting it away.
- Put pried ripe tea in a ceramic or paper canister and finish it within a month or two.
