Most of the old liu bao that survives today was aged in Malaysia. It arrived as the daily tea of Chinese tin miners, was bought and warehoused by the tonne, and was left to sit for decades when the mines closed. Malaysia's heat and humidity barely change through the year, and that steady climate gives Malaysian-stored liu bao its smooth, even character.
Why did so much liu bao end up in Malaysia?
Because it was the tin miners' tea. Between the 1840s and 1880s, large tin deposits were found in British-run Malaya, and large numbers of workers came from southern China to dig them, many from Guangdong. People there already drank liu bao, traditionally to clear heat and damp from the body. Conditions in the mines were hot, wet and hard, and the habit came with them.
Liu bao went from Liu Bao township down the river to Wuzhou, on to Guangzhou or Hong Kong, then by ship to Malaya. Trading houses kept branches in Hong Kong, Penang and Ipoh, the heart of the tin country. The tea travelled in bamboo baskets of 40 to 50kg, often wrapped in large sacks. English-speaking Malaysian Chinese called these gunnies, and some old liu bao is still known by the codes stamped on them.
Why did the mining companies stockpile it?
Because it got better with age and never went off. Some workers are said to have refused to sign with a company that did not supply liu bao. The companies bought it in bulk, which was cheaper, and they noticed that the older baskets drank better than the new ones. So they built warehouses and filled them.
The price was so low that it only made sense in large quantities. Around 200kg of fresh leaf went into a single basket of finished tea, yet whole baskets sold for very little. Liu bao spread beyond the mines too. It became the everyday tea of Malaysian Chinese life, served in restaurants, shops, temples and homes. Older Malaysians still call it simply da ye, big leaf.
What happened when the tin mines closed?
The tea stayed where it was. Tin prices fell through the 1970s and the market collapsed in 1985. Mines closed, and their stocks of liu bao were sold to whoever would buy them or left in storage by the owners. Much of it sat untouched for decades.
In Guangxi, demand dried up at the same time. Farmers could earn more from vegetables than from tea, and some old tea gardens were dug up for vegetables and rice. Production nearly stopped in the 1980s. Many of the old trading houses in Liu Bao township had already gone in the upheavals of the 1960s and 1970s. For years the tea was dismissed as poor man's puerh.
The result is a historical accident. The largest reserves of old liu bao ended up far from where the tea was made, in a country with no winter. For the tea itself, see what is liu bao tea?
What is Malaysia's climate like for ageing tea?
Hot, humid and steady. On the peninsula, temperatures sit in the high twenties to low thirties Celsius most of the year, humidity stays high, and the seasons are marked by rain more than by heat or cold. There is no winter pause and no dry season that draws moisture out of the leaf.
Two things drive ageing. Temperature sets the speed: the chemical and microbial changes in tea run roughly twice as fast for every 10°C rise, within normal room ranges. Humidity decides whether the changes happen at all. Tea kept too dry goes quiet. Tea kept too wet goes mouldy. Malaysia supplies warmth and moisture together, all year, without big swings.
Compare the other traditional storage places:
- Guangzhou and Hong Kong: hot, very humid summers and cooler, drier winters. The tea works hard for part of the year and rests for the rest. Hong Kong storage often gives richer, heavier aged puerh.
- Taiwan: humid, with bigger seasonal swings, especially in the north. Some drinkers think those swings suit puerh.
- Kunming: high, cool and dry. Tea ages slowly there and stays brighter, the style usually called dry storage.
How does Malaysian storage change the taste of liu bao?
It makes liu bao smooth, rounded and even from cup to cup. Malaysian-stored liu bao is known for a clear betel nut aroma, a soft body without sharp edges, and a steady session that does not lurch from one infusion to the next.
For puerh, storage places give different teas more than better or worse ones. A lively sheng can suit a climate with more movement. Liu bao is a gentler tea from a medium leaf, and the steady conditions suit it. Many drinkers who have tried old liu bao from several places prefer the Malaysian-stored examples for exactly that evenness.
How long a tea spent there matters too. Many liu bao spent years in Guangxi or Hong Kong before they reached Malaysia. A tea that went there new and never moved tends to taste smoother and brighter than one of the same age that travelled. Our Ma Bao has been in Malaysia since the 1990s and the Si Bao since the 1980s. The liu bao collection gives the storage history for each tea where it is known.
Is Malaysian storage the same as wet storage?
No. Wet storage, sometimes called traditional storage, means keeping tea in closed rooms that are deliberately hotter and damper than the outside air, often above 30°C with very high humidity. It speeds ageing and changes the tea fundamentally, often with a strong musty character and some mould. Much of what is described as Malaysian storage is closer to natural storage: tea kept in ordinary rooms and warehouses in a humid climate, changing at the pace the weather allows.
Conditions still varied. In China after the war, liu bao baskets were often moved between damp tunnels and drier warehouse rooms to control fermentation. In Malaysia, a warehouse by the sea and a shophouse attic would not keep tea the same way. A label that says "stored in Malaysia" tells you the climate. It cannot tell you the room.
Does "stored in Malaysia" guarantee a good tea?
No. It is useful information, not a grade. The leaf, the processing and the actual storage conditions matter as much as the country. Clean, well-stored liu bao smells of wood, betel nut and old paper. It should not smell sour, damp or of wet cardboard.
A long trip into a new climate also affects what you taste. Aged tea that moves from a humid climate to a dry one, such as inland Australia, can taste flat for a week or two. Open it and let it settle before you judge it. Our guide to storing puerh and liu bao at home covers keeping it well once it arrives.
To taste what storage does, brew two liu bao of similar age side by side, one that stayed in Malaysia and one that did not. The difference is easier to taste than to describe.
