The Great British Tea Heist

In 1848, the British East India Company sent Robert Fortune on a trip to China's interior, an area forbidden to foreigners. Fortune's mission was to steal the secrets of tea horticulture and manufacturing. The Scotsman donned a disguise and headed into the Wu Si Shan hills in a bold act of corporate espionage.

This is an excerpt from For All the Tea in China: How England Stole the World’s Favorite Drink and Changed History by Sarah Rose.

With [his servant] Wang walking five paces ahead to announce his arrival, Robert Fortune, dressed in his mandarin garb, entered the gates of a green tea factory. Wang began to supplicate frantically. Would the master of the factory allow an inspection from a visitor, an honored and wise official who had traveled from a far province to see how such glorious tea was made?

The factory superintendent nodded politely and led them into a large building with peeling gray stucco walls. Beyond it lay courtyards, open work spaces, and storerooms. It was warm and dry, full of workers manufacturing the last of the season’s crop, and the woody smell of green tea hung in the air. This factory was a place of established ceremony, where tea was prepared for export through the large tea distributors in Canton and the burgeoning tea trade in Shanghai.

Although the concept of tea is simple—dry leaf infused in hot water—the manufacture of it is not intuitive at all. Tea is a highly processed product. At the time of Fortune’s visit the recipe for tea had remained unchanged for two thousand years, and Europe had been addicted to it for at least two hundred of them. But few in Britain’s dominions had any firsthand or even secondhand information about the production of tea before it went into the pot. Fortune’s horticultural contemporaries in London and the directors of the East India Company all believed that tea would yield its secrets if it were held up to the clear light and scrutiny of Western science.

Among Fortune’s tasks in China, and certainly as critical as providing Indian tea gardens with quality nursery stock, was to learn the procedure for manufacturing tea. From the picking to the brewing there was a great deal of factory work involved: drying, firing, rolling, and, for black tea, fermenting. Fortune had explicit instructions from the East India Company to discover everything he could: “Besides the collection of tea plants and seeds from the best localities for transmission to India, it will be your duty to avail yourself of every opportunity of acquiring information as to the cultivation of the tea plant and the manufacture of tea as practised by the Chinese and on all other points with which it may be desirable that those entrusted with the superintendence of the tea nurseries in India should be made acquainted.”

But the recipe for the tea was a closely guarded state secret.

In the entry to the tea factory, hanging on the wall, were inspiring calligraphic words of praise, a selection from Lu Yu’s great work on tea, the classic Cha Ching.

The best quality tea must have

The creases like the leather boots of Tartar horsemen,

Curl like the dewlap of a mighty bullock,

Unfold like a mist rising out of a ravine,

Gleam like a lake touched by a zephyr,

And be wet and soft like

Earth newly swept by rain.

Proceeding into the otherwise empty courtyard, Fortune found fresh tea set to dry on large woven rattan plates, each the size of a kitchen table. The sun beat down on the containers, “cooking” the tea. No one walked past; no one touched or moved the delicate tea leaves as they dried. Fortune learned that for green tea the leaves were left exposed to the sun for one to two hours.

The sun-baked leaves were then taken to a furnace room and tossed into an enormous pan—what amounted to a very large iron wok. Men stood working before a row of coal furnaces, tossing the contents of their pans in an open hearth. The crisp leaves were vigorously stirred, kept constantly in motion, and became moist as the fierce heat drew their sap toward the surface. Stir-frying the leaves in this way breaks down their cell walls, just as vegetables soften over high heat.

The cooked leaves were then emptied onto a table where four or five workers moved piles of them back and forth over bamboo rollers. They were rolled continuously to bring their essential oils to the surface and then wrung out, their green juice pooling on the tables. “I cannot give a better idea of this operation than comparing it to a baker working and rolling his dough,” Fortune recalled.

Tightly curled by this stage, the tea leaves were not even a quarter the size they had been when picked. A tea picker plucks perhaps a pound a day, and the leaves are constantly reduced through processing so that the fruits of a day’s labor, which filled a basket carried on a tea picker’s back, becomes a mere handful of leaves—the makings of a few ounces or a few cups of brewed tea. After rolling, the tea was sent back to the drying pans for a second round of firing, losing even more volume at every contact with the hot sides of the iron wok.

With leaves plucked, dried, cooked, rolled, and cooked again, all that was left to do was sort through the processed tea. Workers sat at a long table separating the choicest, most tightly wound leaves—which would be used in the teas of the highest quality, the flowery pekoes—from the lesser-quality congou and from the dust, the lowest quality of all.

The quality of tea is partly determined by how much of the stem and rougher lower leaves are included in the blend. The highest-quality teas, which in China might have names like Dragon Well, or in India FTGFOP1 (Finest Tippy Golden Flowery Orange Pekoe First Grade), are made from the topmost two leaves and the bud at the end of each tea branch. The top shoots taste delicate and mild, and are only slightly astringent; therefore the most pleasant and refreshing.

The distinctive quality of tea comes from essential oils that leach flavor and caffeine into a cup of hot water. These chemical compounds are not necessary for the primary survival of the tea plant’s cells; they are what is known as secondary compounds. Secondary chemicals help plants in many different respects, such as defending them against pests, infections, and fungus, and aiding them in their fight for survival and reproduction. Tea, like other green plants, has several defense systems against predators: Caffeine, for instance, is a natural insecticide. Almost all of tea’s thick waxy leaves, apart from the topmost shoots, are bitter and leathery and difficult to bite through. Tea also has hard, fibrous stalks to discourage animal incursion. Clumsy pickers can compromise the quality of tea by including a leaf farther down the stem and even some of the stem itself; this will make for a harsher, more tannic brew, and in China it will be qualified by names suggesting crudeness, such as dust.

The workers sat at long low tables to pick through the leaves and sort out any pieces of stem. They also looked for any insects that might have tainted the batch, as well as small stones and pieces of grit from the factory floor. Even with a measure of quality control, tea was not a clean product in any sense, which is one of the reasons that Chinese tea drinkers traditionally discard the first cup from any pot. “The first cup is for your enemies,” the saying goes among connoisseurs.

Culinary historians know nothing about who first put leaf to water. But where human knowledge has failed, human imagination has inserted itself. Many Chinese believe that tea was discovered by the mythical emperor Shennong, inventor of Chinese medicine and of farming. The story goes that one day the emperor was reclining in the leafy shade of a camellia bush when a shiny leaf dropped into his cup of boiled water. Ripples of light green liquor soon began to emerge from the thin, feathery leaf. Shennong was familiar with the healing properties of plants and could identify as many as seventy poisonous plants in a daylong hike. Convinced that the camellia tisane was not dangerous, he took a sip of it and found that it tasted refreshing: aromatic, slightly bitter, stimulating, and restorative.
