All true tea comes from a single plant, Camellia sinensis, and the different types of tea come from how its leaves are processed after picking. Tea is usually grouped into six families: white, green, yellow, oolong, black and dark tea, which includes pu-erh. The biggest difference between them is oxidation, the natural darkening of the leaf. Herbal teas such as chamomile or peppermint are not tea at all, though they are brewed the same way.
That single fact clears up most of the confusion around tea. Green tea and black tea are not different plants; they are the same leaves handled differently, the way grapes become very different wines. This guide explains how processing creates each family, gives you a side-by-side chart of all six, shows how to tell them apart in the dry leaf and the cup, and points you to a brewing guide for each so you can start tasting.
Quick facts
- Every true tea comes from Camellia sinensis; the types differ in processing, not plant species.
- There are six families: white, green, yellow, oolong, black and dark tea.
- Oxidation is the main dial. Green tea is stopped before it oxidises; black tea is fully oxidised; oolong sits between.
- Pu-erh is a dark tea, fermented and often aged, and sometimes pressed into cakes.
- Herbal teas are infusions of other plants, properly called tisanes.
One plant, six families
Fresh tea leaves start oxidising the moment they are picked, much as a cut apple turns brown. Tea makers decide how far to let that happen, and then stop it with heat. Nearly every tea goes through some version of these steps, and the families differ in which steps they use and how far each goes:
- Withering. Freshly picked leaves are spread out to lose moisture and soften.
- Fixing, or kill-green. Heat from a pan, steam or oven stops oxidation. Green and yellow teas are fixed early.
- Rolling or shaping. Leaves are rolled, twisted or pressed, which breaks cell walls and shapes the finished tea.
- Oxidation. For oolong and black tea, the leaves are left to darken partly or fully before heat stops the process.
- Drying. The finished leaves are dried to make them stable for storage.
- Extra steps for some families. Yellow tea is gently “sweltered” under cover; dark tea is fermented by microbes, sometimes over years.
White tea is the exception that skips most of this: its buds and leaves are simply withered and dried, which is why it looks so natural and fluffy.
Takeaway: the same leaf becomes six different teas depending on when, and whether, oxidation is stopped.
The six families at a glance
Here is how the families compare, with a brewing guide for each:
| Family | How it is made | Typical flavour | Well-known examples | How to brew it |
|---|---|---|---|---|
| White | Withered and dried, barely processed | Delicate, honeyed, soft | Silver Needle, White Peony | Brewing white tea |
| Green | Heated early to stop oxidation | Fresh, grassy, nutty or savoury | Dragon Well, sencha | Making green tea |
| Yellow | Like green tea, plus a gentle covered resting step | Mellow, sweet, less grassy than green | Junshan Yinzhen | Brew like a delicate green tea |
| Oolong | Partly oxidised, often rolled and sometimes roasted | Floral and creamy to toasty and mineral | Tieguanyin, Da Hong Pao | Brewing oolong tea |
| Black | Fully oxidised | Malty, brisk, honeyed or chocolatey | Assam, Darjeeling, Keemun | Brewing black tea |
| Dark | Fermented by microbes, often pressed and aged | Earthy, smooth, woody, deep | Pu-erh, Liu Bao | Brewing pu-erh |
One naming trap is worth knowing. In China, what the West calls black tea is called red tea, after the colour of the cup, while “black tea” in Chinese refers to the dark tea family. If you shop from Chinese tea sellers, check which family a “red” or “black” tea actually belongs to.
Takeaway: white and green are the least oxidised, oolong sits in the middle, black is fully oxidised, and dark tea is fermented.
How to tell them apart
You can usually place a tea in its family by looking at the leaf and the cup:
| Family | Dry leaf | Colour in the cup | Water it likes |
|---|---|---|---|
| White | Silvery, downy buds or fluffy green-grey leaves | Pale straw to light gold | Below boiling |
| Green | Bright to deep green, flat, curled or needle-like | Pale green to yellow-green | Well below boiling |
| Yellow | Yellow-green buds | Pale yellow | Below boiling |
| Oolong | Green balls to dark twisted strips | Gold to amber to copper | Hot to near boiling |
| Black | Dark brown to black, twisted or finely broken | Red-brown to deep copper | At or near boiling |
| Dark | Dark leaf, often compressed into a cake or brick | Deep red-brown, almost coffee-like | At boiling |
The pattern for brewing follows the pattern for processing: the less oxidised and more delicate the tea, the cooler the water; the more oxidised or fermented, the hotter. For starting times across every family, see our steeping time chart.
Takeaway: pale leaf and pale cup mean gentle water; dark leaf and dark cup mean near-boiling water.
Scented, flavoured and blended teas
Many popular teas are one of the six families with something added. Jasmine tea is usually green tea scented with fresh jasmine blossoms; our guide to brewing jasmine tea explains how the scenting works. Earl Grey is black tea flavoured with bergamot. Masala chai is black tea simmered with spices and milk. Matcha is green tea, shade-grown and stone-ground into powder, and whisked rather than steeped. Genmaicha is green tea mixed with toasted rice.
These teas are brewed according to their base: jasmine green like a gentle green tea, Earl Grey like black tea. Knowing the family underneath tells you how hot the water should be and how long to steep.
Takeaway: scented and blended teas follow the brewing rules of the tea they are made from.
Herbal teas: not tea, but brewed like it
Chamomile, peppermint, rooibos, hibiscus and lemongrass are all infusions of plants other than the tea plant, which is why tea people call them tisanes. They contain no tea leaf unless it is blended in. Most herbal infusions are brewed with water at a full boil and steeped longer than true tea, often five minutes or more, because flowers, roots and bark release their flavour slowly and rarely turn bitter.
Takeaway: herbal teas are tisanes; brew them hot and long.
Where to start
If you are exploring tea for the first time, choose by the flavours you already enjoy:
- You like coffee or strong flavours: start with a black tea, or a dark roasted oolong.
- You like fresh, green, savoury tastes: try a Chinese or Japanese green tea.
- You like floral and fragrant: try a jasmine tea or a light, floral oolong.
- You like gentle and sweet: try a White Peony white tea.
- You like earthy and smooth: try a ripe pu-erh.
Tasting two or three families side by side is the fastest way to learn them. A small gongfu setup makes this easy, because each pot brews just a few small cups; our gongfu tea service pairs a 280 mL titanium teapot with two double-wall cups, and titanium's neutral taste means one pot can move between families without carrying flavours over.
Takeaway: start from the flavours you already love, and taste families side by side.
Frequently asked questions
How many types of tea are there?
True tea is usually grouped into six families: white, green, yellow, oolong, black and dark tea, the family that includes pu-erh. All come from the same plant, Camellia sinensis, and differ in processing. Within each family there are hundreds of individual teas, and herbal teas are a separate category.
What is the difference between green tea and black tea?
Green tea and black tea come from the same plant. Green tea is heated soon after picking to stop oxidation, keeping it fresh and grassy. Black tea is fully oxidised before drying, which turns the leaves dark and gives a malty, brisk flavour. They are brewed differently too, with black tea taking hotter water.
Is herbal tea really tea?
Not strictly. Herbal teas such as chamomile, peppermint and rooibos are infusions of other plants, so they are called tisanes, and contain no tea leaf unless it is blended in. They are brewed the same way as tea, usually with boiling water and a longer steep.
What is yellow tea?
Yellow tea is a rare Chinese tea family made much like green tea, with an extra step in which the warm, damp leaves are gently covered and rested. This mellows the grassy notes, giving a smooth, sweet cup. Brew it like a delicate green tea, with water well below boiling.
What is dark tea?
Dark tea is the family of teas fermented by microbes after processing, often pressed into cakes or bricks and aged. Pu-erh from Yunnan is the best known. Dark teas brew a deep red-brown cup with earthy, smooth, woody flavours, and are usually brewed with water at a full boil.
Which type of tea should a beginner try first?
Start from flavours you already like. Coffee drinkers often enjoy black tea or a roasted oolong; people who like fresh flavours tend to prefer green tea; and anyone who likes floral aromas should try jasmine or a light oolong. Tasting two families side by side is the quickest way to learn.
The short version
All true tea comes from one plant, and processing makes six families: white, green, yellow, oolong, black and dark. The less oxidised the tea, the cooler the water it wants. Scented teas follow their base, and herbal teas are tisanes brewed hot and long.
