Mengku, Menghai, and Fengqing: Yunnan's Three National Large-Leaf Cultivars
Yunnan large-leaf tea is the foundation of pu'er, but "large-leaf" is actually an umbrella term for a whole group of cultivars. Three names stand out: Mengku large-leaf, Menghai large-leaf, and Fengqing large-leaf. When China first carried out a large-scale evaluation of improved tea cultivars in the 1980s, these three were listed together among the first national-level cultivars, and they remain the backbone of Yunnan's tea gardens today.
The First National-Level Cultivars
In 1984, China's tea cultivar evaluation committee approved the first batch of 30 national-level improved tea cultivars, and Yunnan's Mengku, Fengqing, and Menghai large-leaf teas were all among them; registration was completed in 1985. Most sources number them "Huacha No. 12" (Mengku), "Huacha No. 13" (Fengqing), and "Huacha No. 14" (Menghai).
Becoming a national-level cultivar means a variety's vigor, yield, quality, and adaptability have been systematically evaluated and it can be propagated and promoted on a large scale. Many of the seedlings in Yunnan's terrace tea gardens today were bred from these cultivars.
Mengku Large-Leaf
- Origin: Mengku Township, Shuangjiang County, Lincang. The ancient tea gardens around Bingdao (冰島) Village are considered one of the original source gardens of Mengku large-leaf.
- Appearance: arbor type, with a spreading crown, large, long leaves, and plump, very downy buds.
- Flavor impression: high sweetness, full body, relatively mild bitterness and astringency. The sweetness of Bingdao tea is the best-known expression of Mengku large-leaf.
Mengku's story starts with Bingdao: according to local lore, in the 21st year of the Chenghua reign of the Ming dynasty (1485), the chieftain of Mengmeng sent people to bring tea seeds back from Xishuangbanna and planted them in Bingdao, where they grew into a tea garden.

Menghai Large-Leaf
- Origin: Menghai County, Xishuangbanna Prefecture, with the Nannuo Mountain area as an important place of origin.
- Appearance: arbor type, with a spreading crown, broad leaves, and plump, yellow-green buds.
- Flavor impression: strong, intense taste with plenty of cha qi; noticeable bitterness and astringency that fade quickly, followed by a powerful huigan (the sweet aftertaste). What tea drinkers call the "Menghai taste" is closely tied to this cultivar's character.

Fengqing Large-Leaf
- Origin: Fengqing County, Lincang.
- Appearance: arbor type, with large leaves and plump buds with prominent down.
- Flavor impression: clear, lifted aroma and a full body. Fengqing is the home of Dianhong (Yunnan black tea), and besides pu'er, Fengqing large-leaf is an important cultivar for making Dianhong.
Comparing the Three Cultivars
| Cultivar | Main area | Common impression |
|---|---|---|
| Mengku large-leaf | Shuangjiang, Lincang | Sweet, soft, full-bodied |
| Menghai large-leaf | Menghai, Xishuangbanna | Strong, plenty of cha qi, powerful huigan |
| Fengqing large-leaf | Fengqing, Lincang | Clear, lifted aroma, full-bodied; also used for Dianhong |
These flavor impressions are only general directions. The same cultivar grown at a different elevation or in different soil, then processed and stored differently, will taste different.
Cultivar and Mountain
The cultivar is a tea tree's "bloodline," and the mountain is its "home." Mengku large-leaf grown in Bingdao doesn't taste quite the same as Mengku large-leaf grown in other Mengku villages. Knowing the cultivar helps you understand a tea's foundation; knowing the mountain helps you read its personality. Taken together, they make a complete map.

From Improved Cultivars to Terrace Gardens
What makes a national-level cultivar significant is that it can be propagated in large numbers, reliably. From the 1980s on, the tea gardens newly opened in Yunnan widely used seedlings or seeds of Mengku, Menghai, Fengqing, and other improved cultivars, so many of today's terrace gardens are planted with their descendants. Their "bloodline" is close to that of the ancient trees; the differences lie in tree age, root systems, and how they're cultivated.
Visual Clues to the Cultivar
It's hard to identify a cultivar from the dry leaf alone, but the spent leaves after brewing offer some clues:
| What to look at | Typical large-leaf appearance |
|---|---|
| Leaf size | Broad, noticeably bigger than oolong spent leaves |
| Leaf flesh | Thick, soft |
| Buds | Plump, often downy |
| Veins | Prominent, with a thick midrib |
Lay pu'er spent leaves next to Taiwanese oolong spent leaves, and how "large" and "thick" large-leaf tea is becomes immediately obvious.
Other Names Beyond These Three
Yunnan also has many local cultivars and population varieties, such as Jinggu Dabaicha and Yiwu Lüyacha, each with its own character. Some have especially downy, silvery-white buds and are often used for white tea or sun-dried black tea; made into pu'er, they bring different aromatic expressions. The world of cultivars is vast, and Mengku, Menghai, and Fengqing are the best place to start.
Why Cultivar Matters
With the same processing, switching to a different cultivar changes a tea's aroma, sweetness, and bitterness. The cultivar determines what's in a leaf, the origin determines how well those compounds develop, and processing and storage determine how they finally come across in the cup. Knowing the cultivar means understanding a cup of tea from its source.
A Simple Comparison
If you can find teas from the Mengku and Menghai areas, taste them side by side and pay attention to three things: sweetness on entry, how quickly bitterness and astringency fade, and the strength of the huigan. Mengku teas are usually sweet early and only lightly bitter; Menghai teas are directly bitter with a powerful huigan.
FAQ
How do large-leaf and small-leaf teas taste different? Large-leaf teas have thick leaves rich in compounds, giving a full-bodied brew that holds up to many infusions, with more noticeable bitterness and astringency when young; small-leaf teas have a delicate aroma and a lighter body.
Is terrace tea also large-leaf? Yes. Terrace tea is mostly planted with descendants of Mengku, Menghai, and other improved cultivars. The difference lies in cultivation method and tree age, not the cultivar.
What year were these three cultivars recognized? Most sources record approval in 1984 and registration in 1985, as part of the first batch of national-level improved tea cultivars.
Is Fengqing large-leaf used for pu'er too? Yes. Fengqing large-leaf is an important cultivar for Dianhong and is also one of the raw materials for Lincang pu'er.
