What is the difference between green tea and black tea?

Both come from the same plant; the difference is oxidation. Green tea is heated shortly after picking, which stops oxidation and preserves a fresh, vegetal flavor. Black tea is rolled and fully oxidized before drying, which darkens the leaf and creates malty, brisk flavors that stand up to milk. The processing gap also changes brewing: green tea prefers cooler water and short steeps, while black tea handles near-boiling water well.

Oolong is a partially oxidized tea, deliberately stopped somewhere between green and black. Where it lands on that spectrum defines its character: lightly oxidized oolongs taste floral and creamy, close to green tea, while heavily oxidized or roasted oolongs are dark and toasty, edging toward black tea. Good rolled-leaf oolongs are also famously resteepable, opening up across several infusions with slightly different flavor each time.

Are herbal teas like chamomile and peppermint real tea?

Strictly speaking, no. True tea contains leaves of Camellia sinensis, the tea plant. Chamomile, peppermint, rooibos, and similar drinks are herbal infusions — sometimes called tisanes — made from other plants entirely, and they contain no caffeine from tea leaves. They are enjoyable drinks in their own right, but they sit outside the six true tea types of white, green, yellow, oolong, black, and pu-erh.

Which type of tea is best for beginners?

Black tea is the most forgiving starting point: it tolerates boiling water and imprecise timing far better than delicate types, and familiar blends like English Breakfast are easy to find. A darker roasted oolong is another friendly option with more complexity. Green and white teas reward beginners too, but they punish water that is too hot or steeps that run long, so they benefit from a little more care with temperature and timing.

Types of Tea Explained: 6 True Teas and How They Differ

Just Tea Journal · Updated 2026-07-19 · 4 min read

In briefAll true tea comes from one plant, Camellia sinensis, and the six types — white, green, yellow, oolong, black, and pu-erh — differ mainly in how the leaf is processed, especially its level of oxidation. Green tea is heated early to stay fresh and grassy, black tea is fully oxidized for a malty, robust cup, oolong sits deliberately in between, and pu-erh is aged and fermented. Herbal infusions like chamomile are not true tea.

What Are the Types of Tea?

All true tea comes from one plant: Camellia sinensis. The six types — white, green, yellow, oolong, black, and pu-erh — are not different plants but different ways of processing the same leaf. The biggest variable is oxidation, the natural browning reaction that begins when a picked leaf is bruised and exposed to air, the same chemistry that darkens a cut apple. Stop oxidation early and you get a grassy green tea; let it run to completion and you get a malty black tea; land anywhere in between and you are in oolong territory.

Herbal infusions like chamomile, peppermint, and rooibos are not tea in the strict sense — they contain no Camellia sinensis and no caffeine from tea leaves. They are worth drinking, but they belong to a different family.

Tea Oxidation Levels at a Glance

Oxidation is the fastest way to make sense of the tea shelf. From least to most processed:

Type	Oxidation	Typical flavor	Character
White	Minimal	Delicate, honeyed, soft	Least processed; simply withered and dried
Green	None (halted by heat)	Grassy, vegetal, fresh	Heated early to stop oxidation
Yellow	Very light	Mellow, smooth, gently sweet	Rare; green tea plus a slow "sealed yellowing" step
Oolong	Partial	Floral to toasty, wide range	Anywhere between green and black
Black	Full	Malty, brisk, robust	Fully oxidized; the everyday Western cup
Pu-erh	Post-fermented	Earthy, deep, smooth	Microbially aged after processing

The Six True Teas, One by One

White Tea

White tea is the least handled of the six: young buds and leaves are withered and dried, and that is essentially it. The result is pale, subtle, and quietly sweet, often with notes of honey, melon, or hay. Because nothing masks the leaf, quality matters — good white tea rewards attention, while cheap white tea can taste like warm water.

Green Tea

Green tea is heated soon after picking — pan-fired in much of China, steamed in Japan — which halts oxidation and locks in a fresh, vegetal character. Chinese greens lean toasty and nutty; Japanese greens like sencha lean marine and grassy. Green tea is also the least forgiving type in the pot: water that is too hot or a steep that runs too long turns it bitter fast, so cooler water and shorter times are the rule.

Yellow Tea

Yellow tea is the rarest of the six. It starts like green tea, then goes through an extra step — the leaves are wrapped or piled while still warm and left to "yellow" slowly. That slow, gentle smothering rounds off green tea's sharp edges, producing a mellow, smooth cup with little of the grassiness. Genuine yellow tea is produced in small quantities, mostly in China, and priced accordingly.

Oolong Tea

What is oolong tea? It is a partially oxidized tea — deliberately stopped somewhere between green and black — and that "somewhere" is the whole story. Lightly oxidized oolongs are floral, creamy, and close to green tea in spirit; heavily oxidized or roasted oolongs are dark, toasty, and edge toward black tea. Oolongs are also famously resteepable: good rolled-leaf oolong opens up over several infusions, each one a little different.

Black Tea

Black tea is fully oxidized, which is why it brews dark, tastes malty and brisk, and stands up to milk and sugar. It is the backbone of English Breakfast and Earl Grey blends and most iced tea. Black tea is the forgiving choice for beginners: it tolerates boiling water and a slightly careless timer far better than green tea does. Assam tends toward bold and malty, Darjeeling toward light and muscatel, Ceylon toward crisp and citrusy.

Pu-erh Tea

Pu-erh, from China's Yunnan province, is a post-fermented tea: after initial processing, the leaves are aged and transformed by microbes, either slowly over years (raw, or sheng) or through an accelerated wet-piling process (ripe, or shou). The result is earthy, dark, and unusually smooth, with none of black tea's briskness. It is the one tea routinely sold in pressed cakes and the one that can genuinely improve with age.

Green Tea vs Black Tea: The Difference

The difference between green and black tea is oxidation, not the plant. Green tea is heated shortly after picking so the leaf stays green and the flavor stays fresh and vegetal. Black tea is rolled and fully oxidized before drying, turning the leaf dark and the flavor malty and strong. That processing gap also changes brewing: green tea wants cooler water and short steeps, while black tea takes near-boiling water happily. Caffeine overlaps more than the folklore suggests — it depends heavily on the specific leaf, how much you use, and how long you steep.

Brewing: Where Type Meets Method

Knowing your tea type is half the job; steeping it correctly is the other half. Each type has its own preferred water temperature and time — get those right and even a modest tea improves dramatically. Our companion guide to steeping times and temperatures for every type gives the exact numbers, and the rest of our brewing basics guides cover ratios, resteeping, and how to adjust to taste.
