Liu Bao is a Chinese dark tea from Cangwu County, around Wuzhou in Guangxi, made by heaping and piling the leaf so that it ferments and then leaving it to age. The result is a smooth, earthy, woody cup, and for much of its modern history a great deal of it was made for export, bound for Hong Kong and the Chinese communities of Southeast Asia, the old Nanyang.
If an older relative in Malaysia has ever poured you a dark, mellow tea and told you it was "good for the heat", there is a fair chance it was Liu Bao. It deserves to be better known, and to be described honestly, because a fair amount of what is said about it does not hold up.
Where Liu Bao comes from
The tea takes its name from Liubao town in Cangwu County. China's national standard for it, GB/T 32719.4-2016, recognises the local Cangwu tea population as a raw material alongside larger-leaf cultivars, and grades the finished tea from a special grade down to grade six. Since 2011 it has also been a protected geographical indication tied to the Wuzhou area.
The oldest written mention usually quoted is a single line from a Qing-dynasty gazetteer of Cangwu County, noting that tea grown at Liubao was rich in taste and kept overnight without spoiling. Historians disagree about which edition of the gazetteer that line first appeared in. You will also read that Liu Bao was an imperial tribute tea, one of the "twenty-four famous teas" of the Qing, or that it has fifteen hundred years of history. We could find no period document behind any of them, so we leave them out.
How it is made, and how it differs from ripe pu'er
Under the national standard, the fresh leaf is heated to stop it oxidising, rolled, heaped for a spell, rolled again and dried. That rough tea is then sorted, steamed and piled once more, sometimes pressed into bricks, and finally set aside to age. The piling is where the character comes from. Researchers who sequenced Liu Bao samples found two groups of moulds, Eurotium and Aspergillus, dominating almost every one, including Eurotium cristatum, the same fungus behind the "golden flowers" prized in some other dark teas. Over the fermentation, the sharp catechins of green leaf fall away and compounds such as gallic acid rise, which helps explain why a good Liu Bao drinks round rather than astringent.
Today's method is younger than most people assume. Cold-water piling was worked out at the state-run tea factory in Wuzhou during the 1950s and was in volume production by 1958 at the latest; a trade manual published the following year describes the factory's switch to it. Ripe pu'er's own piling method came out of Yunnan in the 1970s, well over a decade later. Both methods were aimed largely at export buyers, above all in Hong Kong, who already knew and liked the mellow taste of older tea.
So what separates them in the cup? Place and leaf, first of all: Guangxi rather than Yunnan's big-leaf country. To our palate, set a brick of ripe pu'er such as our Chen Xiang Old Tea Brick beside a Liu Bao and the pu'er reads deeper and more forest-floor, while Liu Bao tends to be lighter on its feet, woody, a little nutty. Old hands describe aged Liu Bao as having a "betel-nut" aroma. It is a traditional trade term for that dry, woody, faintly medicinal note that comes with years of storage, not a literal flavour, and you will not find it in the national standard, which simply asks for a clean aged fragrance.
Why Liu Bao belongs to the Nanyang
For generations the tea travelled downriver from Wuzhou to Guangzhou and Hong Kong, and from there by sea to the Chinese communities of Southeast Asia. Much of what we know about its life at this end of the journey comes from memory rather than ledgers. Elderly Malaysians interviewed by tea writers recall it being drunk by tin miners in Ipoh, Kuala Lumpur, Kuantan and elsewhere, who believed it helped with the "dampness and heat" of the mines. They are oral histories, but they help explain why the taste of Liu Bao is still so familiar to older drinkers in Malaysia and beyond.
Our 2013 Liu Bao tea brick comes from Wuzhou and has had more than a decade to settle. For something gentler, the Tea Chapter Liu Bao Blend pairs that same 2013 tea with fifteen-year-aged tangerine peel, which lifts the woodiness with a soft citrus note.
How to brew Liu Bao
Liu Bao wants fully boiling water. Break off a piece from a brick, give it a quick rinse to wake the leaf, and pour that first water away. In a small pot, around 6–8 g of leaf to 250–350 ml of water for about 30 seconds works well, adding ten seconds or so each round. If you brew gongfu style with more leaf in a smaller vessel, keep the early infusions short, ten to twenty seconds, and let them lengthen as the leaf opens.
A round-bellied pot like our Xi Shi teapot suits compressed dark tea nicely, as the broken pieces have room to unfurl.
In Singapore you do not need to add humidity; what you need is a clean, odour-free spot with a little airflow, away from direct sun. Our guide to storing tea in Singapore's humidity covers the details.
Frequently asked questions
Is Liu Bao a type of pu'er?
No. Both are Chinese dark teas made by piling and ageing the leaf, but Liu Bao comes from Guangxi and has its own national standard, while pu'er comes from Yunnan.
Is Liu Bao good for your health?
Liu Bao is traditionally associated with cooling the body in hot, damp weather, and some small studies have looked at it, but none so far compared it against a placebo, so we enjoy it as a tea rather than a remedy.
What are the golden specks I sometimes see in dark tea?
In Liu Bao they are generally put down to Eurotium cristatum, the golden flower mould that researchers find among the dominant fungi in this tea. Fuzzy, cottony growth or a musty smell that lingers after rinsing is a different matter, and that tea should not be drunk.
Does Liu Bao get better with age?
It changes with age, growing smoother and woodier, and many drinkers prefer it older. How it has been stored matters as much as how long, and a vintage on the label cannot tell you that.
