Tieguanyin: Green vs Traditional Roasted, and How Not to Buy "Hay"

Tieguanyin (铁观音, "Iron Goddess of Mercy") is a rolled oolong from Anxi County in southern Fujian, China. It comes in two styles: the modern green style, lightly oxidized and barely roasted, with an intense orchid and lilac aroma; and the traditional roasted style, darker and warmer, with honey and toasted grain. Good Tieguanyin is made from whole leaves, unfurls into large leaves in the gaiwan and gives 6–8 floral, creamy steeps. Tea that tastes of hay is usually not Tieguanyin at all.

Tieguanyin was the first oolong I really loved, and also the first one that disappointed me. The good one came from a friend's tin: tight jade-green balls that opened into whole leaves, and a lilac smell that filled the room before I'd even poured. The bad one came in a pretty box from a gift shop, and it tasted of dry grass. For a while I thought I'd just been lucky the first time. I hadn't. They were two different teas that happened to share a name, and learning to tell them apart is the most useful thing I can pass on about Tieguanyin.

Where Tieguanyin comes from#

Anxi County sits in the hills of southern Fujian, inland from the port city of Xiamen. It's been a tea county for centuries, and today it's so identified with this one tea that it's promoted as the "capital of Tieguanyin". Tieguanyin is both the name of the tea and of the cultivar it's made from, a bush with thick, glossy leaves.

Two legends explain the name:

• The farmer Wei. A poor farmer tended a neglected temple of Guanyin, the goddess of mercy. In a dream, she showed him a tea plant in a cave behind the temple. He grew it, shared cuttings with his neighbours, and the village prospered.
• The scholar Wang. A scholar found an unusual tea bush among the rocks, grew it, and later presented the tea to the Qianlong Emperor, who named it after the heavy, iron-dark leaf and the goddess.

Neither is history in the strict sense, but both are still told in every Anxi tea shop.

How Tieguanyin is made#

Tieguanyin is picked as a shoot of three top leaves, still attached to a small section of stem. From there:

1. Sun and indoor withering. A few hours outdoors softens the leaf and begins turning grassy aromas floral.
2. Shaking and resting (zuo qing). Many cycles over many hours. Each shaking bruises the leaf edges, which oxidize faster than the centre: the classic oolong "green leaf with a red rim".
3. Kill-green. A hot drum or wok stops oxidation.
4. Ball rolling. The signature step: the leaves are wrapped tightly in cloth and rolled, again and again, then loosened and rolled again, until they're pressed into tight balls. This is what makes Tieguanyin look the way it does, and it's hard, skilled work.
5. Drying, and for the traditional style, roasting.

What comes out of the farmer's workshop is still maocha (毛茶), rough tea: balls mixed with stems, broken bits and dust. Turning it into finished Tieguanyin is a separate job. The stems are picked out by hand, which takes around half an hour or more per half kilo, and the tea is sieved to remove fragments. Roughly half the weight of the maocha is lost on the way. The dust and broken pieces don't disappear: they end up in cheap tea bags.

This is also why good Tieguanyin costs what it does. You're paying for the hand-sorting as much as for the leaf.

Green vs traditional roasted Tieguanyin#

The green style is what most shops sell and what most people picture when they hear "Tieguanyin". It's spectacular when fresh and good, and flat when old or cheap. The traditional style is harder to find outside China, rewards patience, and is my own preference these days: it keeps the orchid heart of Tieguanyin but gives it a spine.

There's also a middle path, sometimes called medium roast or "Chen Xiang" when it's been aged. In southern Fujian and Taiwan, some people store roasted oolong for years in clay jars and re-roast it every year or few years, which turns it plummy and deep. It's a niche, but a lovely one.

Spring vs autumn#

Tieguanyin has two main harvests, and each has its fans.

• Spring (春茶): the fullest and most abundant harvest; bright, fresh, with plenty of body.
• Autumn (秋茶): smaller leaves and a slower season; traditionally prized for its aroma, which many drinkers consider the most refined. Less punchy than spring, but finer.

Shops also sell summer Tieguanyin, which is generally the weakest: thinner and more bitter. If a label doesn't mention the season at all, assume it's not the best of either.

Why some Tieguanyin tastes like hay: Zhong Cha#

If you've ever read a review saying "Tieguanyin tastes like hay", there's a good chance the reviewer was drinking Zhong Cha (种茶). It's tea made from the same kind of bushes on lowland plantations, sometimes only 150–200 metres lower than the good gardens. That small difference in altitude is enough to make a much thinner, flatter tea. In China it's the sort of oolong restaurants pour for free with a meal. Abroad, it's regularly sold as "Tieguanyin" at Tieguanyin prices.

How to tell:

The spent leaf is the most honest test. Tip the leaves into a white bowl after the session and spread a few out. Good Tieguanyin opens into big, glossy, whole leaves. If you see fragments, twigs and thin leaves, you've learned what you paid for.

Buying tips:

• Look for the season and the style on the label: "Autumn 2025, traditional roast" beats "Premium Tieguanyin".
• Avoid pretty gift boxes with no details. That's where I found my hay.
• Buy a sample first. Tieguanyin quality varies more from shop to shop than almost any other famous tea.

How to brew Tieguanyin#

The balls take a round or two to open, so the second and third steeps are usually the best. Use a gaiwan big enough for the leaves to expand: 6 g of Tieguanyin fills a 100 ml gaiwan to the lid once it's unfurled. Western-style, use 3 g per 250 ml at 90 °C for 2–3 minutes. Tieguanyin is also excellent cold-brewed: a few grams in a litre of cold water in the fridge overnight gives a sweet, floral summer drink. See cold brew tea.

Storing Tieguanyin#

• Green style: airtight and cool. In China, green Tieguanyin is often kept in large freezers and packed just before sale. At home, vacuum packs in the fridge work, but let a pack come to room temperature before opening it, so moisture doesn't condense on the leaf. Drink within a year.
• Traditional roasted: airtight, dark, room temperature. It keeps for years and can improve.
• Both: away from smells. Tieguanyin absorbs them eagerly.
