Drinking Pu-erh Tea: 10 Honest Facts Beyond the Health Hype

Shop our Pu Erh tea collection—available in both ripe and raw varieties!

Search for pu-erh tea online and you'll find long lists of health promises. We make pu-erh in Menghai, Yunnan, and we'd rather be straight with you: pu-erh is a drink, not a treatment. It doesn't replace medicine, a healthy diet or advice from your doctor or pharmacist, and if you have symptoms or a health concern, they are the right people to ask.

What we can tell you is what pu-erh actually is, what's in the cup, how people in Yunnan drink it, and how to enjoy it sensibly. Here are ten honest things worth knowing before you buy.

1) It's a Fermented Tea from Yunnan

Pu-erh is made from the large-leaf variety of the tea plant (Camellia sinensis var. assamica) grown in Yunnan province in southwest China. After picking, the leaves are withered, pan-fired, rolled and sun-dried into "maocha," then usually pressed into cakes, bricks or small tuo.

There are two main styles. Raw (sheng) pu-erh is pressed straight from maocha and changes slowly over years of storage. Ripe (shou) pu-erh goes through an extra step of accelerated fermentation before pressing, which makes it dark and mellow from the start.

2) It Contains Caffeine

All pu-erh contains caffeine, because it's made from the tea plant. A cup usually has less caffeine than a typical cup of coffee, and ripe pu-erh generally has a little less than young raw pu-erh. How you brew matters a lot: more leaf, hotter water and longer steeps all pull out more caffeine.

3) What's in the Cup

Like other teas, pu-erh contains polyphenols such as catechins, along with amino acids such as L-theanine and the natural compounds that give it color, aroma and a slightly drying feel on the tongue. Fermentation and aging change this mix over time, which is part of why an aged cake tastes so different from a fresh one.

You'll see these compounds used online to support all kinds of health promises. We don't make those claims. Tea is something to enjoy, not a supplement to take for an effect.

4) Ripe Pu-erh Is Made by Microbial Fermentation

Ripe pu-erh is made with a process called wo dui, or "wet piling." Maocha is piled, moistened and turned over several weeks while naturally present microbes ferment the leaves. This is what gives ripe pu-erh its dark red liquor and smooth, earthy taste.

You may read that this makes pu-erh "probiotic." Brewed tea is made with near-boiling water and is not a probiotic food, and we don't describe it that way. Well-made ripe pu-erh should smell clean and earthy, never musty or sour.

5) In Yunnan, It's an Everyday Drink with Meals

In Yunnan, pu-erh has long been drunk after rich, meaty meals, and it's common at the table in Guangdong and Hong Kong dim sum restaurants, where it's often simply called "bo lei." Pressed pu-erh was carried along the Tea Horse Road and drunk daily by Tibetan herders, often churned with butter and salt.

That history tells you how people enjoy pu-erh: as a strong, warming everyday tea that pairs well with food. It isn't a reason to expect any particular effect from it.

6) It Makes a Calm Daily Ritual

Much of pu-erh's appeal is the ritual. Breaking a few grams from a cake, rinsing the leaves and brewing many short infusions in a small teapot or gaiwan (gongfu style) is slow and absorbing. Many people simply like having a quiet ten minutes with a pot of tea in the middle of a busy day.

7) It Isn't a Weight-Loss Tea

Pu-erh is often sold online as a "slimming" or "fat-burning" tea. We don't sell it that way, and you shouldn't buy any tea expecting it to change your weight. A plain cup of pu-erh has almost no calories, so it can be a satisfying swap for a sweetened drink if that's something you want, but that's simply because it's unsweetened.

8) Know Your Caffeine Limits

If you're sensitive to caffeine, start with a small cup of ripe pu-erh, brew it lightly, and drink it earlier in the day. Too much caffeine can make some people jittery or keep them awake. In the evening, a caffeine-free herbal infusion is the easier choice.

If you're pregnant, breastfeeding, taking medication or managing a health condition, ask your doctor how much caffeine and tea is right for you. Our article on pu-erh tea and pregnancy covers the questions people ask most.

9) Quality and Storage Matter

Because pu-erh is stored for months or years, how it's kept matters. Good pu-erh should smell clean. Don't drink tea that shows white or green fuzzy mold or smells musty or sour. Store cakes away from strong odors, direct sun and damp, in a stable, moderately dry place.

Buy from producers who can tell you where and when the tea was made. Our teas are made by Chen Sheng Hao in Menghai, Yunnan, a pu-erh maker since 2007, and are China Green Food certified. Also let freshly boiled tea cool a little before you drink it rather than sipping it scalding hot.

10) How to Brew It to Enjoy It

A simple gongfu method: use about 5-7 g of leaf for a 100 ml teapot or gaiwan, rinse once with boiling water for a few seconds and discard, then brew short infusions of 10-20 seconds, adding a few seconds each round. Use boiling water for both ripe and raw pu-erh.

If you prefer a mug, use 2-3 g of leaf in 250 ml of water and steep for 2-4 minutes, then taste and adjust. One portion of good leaf can be steeped many times.

Choosing Your First Pu-erh

If you like smooth, dark, earthy teas, start with a ripe pu-erh. If you enjoy green or oolong teas and like a bright, lively cup, try a raw pu-erh. Not sure? Our tea samples let you taste a few before buying a full cake, and orders over $70 USD ship free.
