Origins and Legend
The tale of tea begins in China more than four thousand years ago, in misty highlands where Camellia sinensis grew wild. Legends credit Emperor Shen Nong with its discovery around 2737 BCE, when leaves drifted by chance into a pot of boiling water. The aroma intrigued him, the taste refreshed, and tea’s journey into human culture began.
Whether myth or history, tea quickly embedded itself in ritual, medicine and daily sustenance. Ancient texts praised it for clearing the head and lightening the body. Monks adopted it as an aid to meditation, the gentle caffeine supporting long hours of study and prayer. Over centuries, tea spread through dynasties, its preparation refined into art forms that still shape culture today.
The Spread of Tea
From its Chinese cradle, tea journeyed outward with merchants, monks and explorers. By the first millennium, it was known across East Asia. Japanese envoys carried seeds home in the ninth century, giving rise to centuries of cultivation and the meditative tea ceremony. In Tibet, tea was churned with yak butter and salt, sustaining highland communities against harsh climates.
Tea entered European life in the seventeenth century, carried by Portuguese traders and later dominated by the Dutch and English East India companies. In Britain, it shifted from a luxury to a daily necessity, entwined with sugar imports and porcelain trade. By the eighteenth century, the ritual of afternoon tea had become a cornerstone of social life, weaving tea into the fabric of empire.
Australia’s relationship with tea began with colonisation. For much of the nineteenth and twentieth centuries, tea was the default hot beverage, drunk by workers, families and travellers. Even today, Australia maintains one of the higher per-capita tea consumptions outside Asia, though coffee has since challenged its dominance. Small plantations now exist in tropical Queensland and northern New South Wales, producing niche green and black teas suited to local soils.
Varieties of Tea
All true teas - green, black, oolong, white, yellow and pu-erh - come from the same plant species, Camellia sinensis. Their differences arise from processing, oxidation, and terroir:
- Green Tea - Unoxidised, steamed or pan-fired to preserve freshness. Flavours range from grassy and seaweed-like to nutty and sweet.
- Black Tea - Fully oxidised, producing dark colour and bold flavour. Assam and Darjeeling are famous examples, beloved for their strength and complexity.
- Oolong - Partially oxidised, bridging green and black. Floral, fruity, and endlessly variable.
- White Tea - Minimally processed young leaves or buds, delicate and subtle.
- Pu-erh - Fermented and aged, earthy and robust, often pressed into cakes.
Beyond these, herbal infusions - chamomile, rooibos, peppermint - are often called “teas” though botanically distinct. In Australia, lemon myrtle and wattleseed infusions sit alongside imported leaves, weaving native flavours into the tradition.
Cultivation and Processing
Tea thrives in highland regions with mist, rain and cool temperatures. Leaves are hand-plucked - the youngest bud and top two leaves are prized for quality. Timing and precision matter: a day’s delay can alter flavour dramatically.
Withering. Freshly plucked leaves are spread to reduce moisture and soften texture.
Rolling. Leaves are twisted or rolled to break cell walls, releasing enzymes and shaping oxidation.
Oxidation. The crucial stage: enzymes react with oxygen, turning leaves darker and altering flavour. Green tea is heated early to halt this; black tea is fully oxidised.
Drying. Heat or sun stabilises the product, locking in flavour and preparing it for storage.
Each style balances these steps differently. A Japanese sencha may be steamed within hours of harvest; a pu-erh might ferment for years, developing depth and complexity. Skilled hands and keen eyes ensure that every batch expresses its intended character.
Tea in Culture
No other drink has carried so much cultural weight across so many societies. In Japan, the chanoyu ceremony elevates tea to ritual, embodying simplicity, harmony and respect. In Britain, afternoon tea remains a symbol of civility, complete with scones and cucumber sandwiches. In Morocco, mint tea poured from height signals hospitality; in India, sweet, spiced chai is sold on every corner, binding communities together.
Australia has long mirrored British traditions, but today tea culture is diversifying. Specialty tea houses in Sydney and Melbourne offer tastings as elaborate as wine flights, with notes of terroir and leaf processing explained in detail. At the same time, a humble teabag remains part of the daily rhythm for many households, whether at breakfast tables or during afternoon breaks in offices and workshops.
Health and Debate
Tea contains caffeine, though generally less than coffee, offering a gentler stimulant effect. It also carries L-theanine, an amino acid linked to relaxation and focus, which may explain tea’s dual power to calm and invigorate.
Polyphenols in tea are studied for antioxidant properties, with potential links to heart health and metabolism. Green tea in particular is associated with these benefits, though much depends on preparation and quantity.
Debates arise over pesticides in large-scale production, labour conditions in plantations, and environmental impacts. Ethical sourcing schemes aim to improve fairness, while organic certification addresses concerns about chemicals. Australian buyers increasingly seek transparency, valuing both taste and sustainability in equal measure.
Brewing Traditions
| Tea Type | Recommended Temperature | Steeping Time | Tasting Notes |
|---|---|---|---|
| Green Tea | 70–80°C | 2–3 minutes | Can become bitter if steeped too long or with water that is too hot. |
| Black Tea | 95–100°C | 3–5 minutes | Bold and full-bodied, often served with milk. |
| Oolong | 85–90°C | Multiple short infusions | Reveals layers of flavour. |
| White Tea | 75–85°C | 4–5 minutes | Gentle treatment preserves subtlety. |
| Pu-erh | Rinse quickly with hot water, then steep at 95°C | Multiple infusions | Multiple infusions are recommended. |
Buying, Storing & Serving
Loose-leaf tea offers greater depth than bags, allowing leaves to unfurl fully. Quality varies: whole leaves indicate care, while dust and fannings are typical of lower-cost blends.
Store tea in airtight containers away from light, heat and moisture. Green teas keep for months; darker teas age well, sometimes improving with time. Pu-erh cakes can develop complexity over decades, akin to fine wine.
Serving vessels matter too. Porcelain teapots retain heat gently, while cast iron teapots hold warmth longer. Glass allows the beauty of unfurling leaves to be admired. In Australia’s warmer climates, iced teas and cold brews have become popular alternatives, steeped slowly in the fridge for a refreshing summer drink.
Tasting and Pairing
Tea tasting begins with aroma. Green teas may suggest cut grass or sea breeze; black teas, malt and spice; oolongs, flowers and stone fruit. Sip slowly, noting body, astringency, sweetness and aftertaste.
Pairings reveal another dimension. Robust black teas stand alongside rich breakfasts; delicate green teas accompany seafood; smoky lapsang soothes with cheese or charcuterie. In Australia, tea is increasingly paired with native foods - lemon myrtle shortbread with green tea, wattleseed biscuits with oolong.
Like wine or coffee, tea rewards attention. The more one notices, the more subtle patterns emerge, from the soil of Darjeeling to the volcanic slopes of Uji or the tropical valleys of Queensland.
