he would send out free samples of his tea.
In the world of tea lovers, few things are as recognisable as the tea bag.
It’s a simple staple, a comforting companion in kitchens everywhere.
Yet this everyday item exists thanks to a happy accident. What began as clever packaging turned into a brewing revolution, changing how people enjoy tea.
A New York merchant’s creativity and an unintentional discovery came together to reshape tea culture.
This is the story of the tea bag’s invention—a testament to how the best ideas often arise from chance rather than careful planning.
How was Tea Originally Sold?
In the early 1900s, tea was typically sold loose and brewed in teapots.
Wealthy tea drinkers in Britain and America enjoyed their brews steeped from high-quality loose leaves.
However, transporting tea internationally, particularly from regions like India, Sri Lanka, and China, posed challenges.
Merchants constantly sought ways to make the process more efficient and attractive to their customers.
In 1908, an American tea merchant named Thomas Sullivan unintentionally changed the course of tea history.
Sullivan, based in New York, sold fine teas to his clients by the pound. To entice new buyers, he would send out free samples of his tea.
It was the packaging of these samples that led to the accidental invention of the tea bag.
Accidentally Inventing the Tea Bag
Instead of sending loose tea in tins, Thomas Sullivan shipped his tea samples in small silk pouches to save money.
The silk pouches were meant to act as containers for the tea during transportation, and the customers were supposed to cut them open and use the loose tea as usual.
But Sullivan’s clients misunderstood his intent.
Believing that the silk pouches were designed to be immersed directly in hot water, they began brewing their tea with the pouch still intact.
To their surprise, the method worked.
The tea infused through the silk, delivering a flavourful brew without the mess of loose leaves. It was a revelation for those who appreciated a quick and tidy way to enjoy their tea.
Perfecting the Tea Bag & Gaining Prominence
Although the silk pouches were innovative, they weren’t particularly practical for mass production.
Silk was expensive, and the bags often tore when used.
Recognising the potential of his accidental invention, Sullivan began experimenting with other materials.
By the 1920s, gauze and paper were introduced, making the tea bag more durable and affordable. This marked the beginning of the tea bag’s journey towards widespread adoption.
But it wasn’t just Sullivan who was perfecting the tea bag.
German inventor Adolf Rambold invented a tea bag packing machine called Pompadour in 1929.
In 1949, he invented a modern form of tea bag, which featured two chambers.
Meanwhile, American inventor William Hermanson patented the first heat-sealed paper tea bag, ensuring no one needed to use tea bags that resembled small sacks ever again.
The tea bag gained traction in America by the early 20th century, especially after the introduction of machine-made tea bags in the 1920s.
This innovation allowed for mass production, making tea bags widely accessible.
While companies like Lipton helped popularise tea globally, it was firms such as Tetley that initially focused on the commercialisation of tea bags.
Notwithstanding Britain’s modern reputation as a land of tea drinkers, tea bags only began to gain widespread adoption there after the end of the Second World War, lagging behind the United States by a few decades.
The introduction of the staple pin to secure tea bags simplified the brewing process, making it easy for people to enjoy their tea without the fuss of loose leaves and teapots.
Making its Way across the World
By the 1950s and 1960s, tea bags were becoming more common in British households, but they still faced resistance from tea purists who considered them inferior to loose-leaf tea.
Meanwhile, the tea bag began spreading to other parts of the world.
In continental Europe, where coffee often dominated, tea drinking took on a different character as the tea bag offered a practical way for occasional tea drinkers to enjoy a quick and mess-free brew.
Its popularity began to grow, particularly in countries like Germany and the Netherlands.
In Asia, where tea traditions were deeply ingrained and varied widely from region to region, the tea bag was initially met with scepticism.
Countries like China, Japan, and India, with their rich histories of tea culture, valued the ritualistic and artisanal aspects of tea preparation, which the tea bag could not replicate.
But over time, their convenience found a niche even in these markets, particularly in urban areas and for export purposes.
The likes of Lipton, Tetley and Twinings marketed tea bags as a modern, practical solution, using advertising campaigns to promote their convenience and reliability.
Innovations in materials and design, such as the introduction of heat-sealed paper bags and the development of pyramid-shaped bags, further enhanced their appeal, allowing for better infusion and flavour.
By the late 20th century, tea bags had achieved prominence in much of the world.
While loose-leaf tea continued to thrive among connoisseurs and in traditional tea-drinking cultures, the tea bag transformed tea consumption, making it accessible to a broader audience.
Tea in South Asia
Tea was introduced to South Asia during British colonial rule as part of an effort to reduce Britain’s dependence on Chinese tea.
The East India Company transformed tea from a luxury item to a widely consumed commodity.
Large-scale plantations were established in regions like Assam and Darjeeling in the mid-1800s, where the climate and terrain were ideal for cultivation.
Darjeeling tea soon gained fame as the “champagne of teas” for its muscatel aroma and delicate flavours.
The industry relied on local and indentured labour, and tea became a cornerstone of British culture, with vast quantities exported to Britain to fuel the growing popularity of afternoon tea rituals.
India
In India, tea quickly transcended its colonial roots to become deeply embedded in local culture.
Street vendors (chai wallas) popularised tea as an affordable and communal experience, blending it with spices like ginger, cardamom, and cinnamon to create chai masala.
These vendors made tea a part of daily life across social classes, fostering connections and establishing chai as a symbol of Indian hospitality.
Pakistan
In Pakistan, tea developed a similarly significant cultural presence, despite the country being a major importer of tea leaves.
Drawing inspiration from Tibetan tea traditions, Pakistan’s chai is often rich and aromatic, featuring flavours like cinnamon and caramel.
Roadside tea stalls (dhabas) cater to travellers and truck drivers, serving steaming cups of tea as a refreshment.
A standout variety is Kashmiri chai, or “noon chai”, a pink-hued tea made with green tea leaves, milk, and a pinch of salt, often garnished with nuts.
Sri Lanka
Sri Lanka’s tea journey began in the 1860s, when Scottish planter James Taylor introduced cultivation to the island, experimenting with tea plants from China.
His success laid the foundation for a thriving tea industry, supported by Tamil labourers from South India who worked under challenging conditions.
The British controlled the production and export of tea, ensuring profits flowed back to Britain.
Today, Sri Lanka remains a leading tea exporter, with its Ceylon tea celebrated for its bright, brisk flavours. Tea tourism has also flourished, with estates offering tastings and tours.
Across South Asia, tea evolved from a colonial export into a cultural cornerstone, shaped by local traditions and preferences.
From India’s spiced chai to Pakistan’s savoury Kashmiri chai and Sri Lanka’s iconic Ceylon teas, tea has become a unifying force, weaving itself into daily rituals and fostering connections.
The accidental invention of the tea bag serves as a charming reminder that significant innovations often emerge from unforeseen circumstances rather than meticulous planning.
Thomas Sullivan’s cost-saving initiative and his customers’ ingenuity led to a revolution in how we drink tea.
So, as you relish your next cup, take a moment to reflect on the fortuitous circumstances that gave rise to the tea bag.
