Tea Types & Varieties: A Complete List of the 6 Categories
All true tea comes from one plant: Camellia sinensis. The six tea types—white, green, yellow, oolong, black and pu-erh—are not different plants, but different choices in processing: withering, heating, oxidation (browning) and, in the case of pu-erh, fermentation. Those choices shape the tea colours in the cup, the flavour, and how stimulating the tea feels. This page is your calm map—start here, then explore each type in depth.
Rare and refined, yellow tea includes a gentle resting stage that softens the sharper edges found in some green teas. The result is a mellow, rounded cup with smooth sweetness and a silky, understated mouthfeel—often calmer and less brisk than green.
Oolong tea is partially oxidised, spanning flavours from floral and creamy to toasty, mineral, and roasted. If you’re researching what is oolong tea, it’s defined by the maker’s craft in shaping aroma and texture. Does oolong tea have caffeine? Yes—usually moderate.
From Yunnan, Pu Er Cha Tea (Pu’er / pu-erh) is a post-fermented category valued for earthy depth and ageing potential. It is typically Raw (Sheng) or Ripe (Shou), ranging from bright to dark and smooth. Caffeine is present, but highly variable by material and brew.
Tea Colours Explained: Why Tea Brews Pale, Gold, Amber or Dark
Although tea can look almost colourless in the cup or deep enough to appear near-black, most tea colours come down to one quiet variable: how much the leaf is allowed to oxidise before it is dried. Oxidation is the natural “browning” reaction that happens when tea leaves are bruised and exposed to oxygen — the same process that turns a cut apple darker over time.
That single choice shapes both colour and flavour. White tea is gently withered and dried with minimal oxidation, so it brews pale and soft. Green tea is heated early to stop oxidation, keeping a brighter, greener character. Oolong sits between the two — partially oxidised — often giving golden, amber cups. Black tea is fully oxidised, which is why it tends to brew darker, maltier and more robust.
One important note: Pu-er teas (and other dark teas) is not simply “more oxidised” — it is fermented, meaning its character develops through microbial activity over time, creating deeper, earthy tones that sit outside the simple light-to-dark oxidation spectrum.
Are Herbal Teas "Real" Tea?
Strictly speaking, herbal teas aren’t real tea. When people ask "what are the herbal teas?", they are usually referring to infusions made from flowers, roots, or spices. In the tea world, these are correctly called tisanes because they do not come from the tea plant (Camellia sinensis).
Common herbal infusions include:
-
Peppermint & Ginger: Often used for digestion.
-
Chamomile & Lavender: Popular for sleep.
-
Rooibos: A distinct South African "Red Bush" infusion.
Is Green Tea Herbal Tea? No. This is a common confusion. Green tea is a "true tea" made from Camellia sinensis, so it naturally contains caffeine (approx. 20–45 mg per cup). Herbal infusions are usually made from ingredients like fruit or flowers, making them naturally caffeine-free.
Herbal infusions belong in a calm daily ritual—especially in the evening, when you want warmth without stimulation. Think of them not as a "tea type," but as a caffeine-free "tea moment."
Types of Tea List (At a Glance)
For a quick comparison, the table below outlines the six true tea categories based on their oxidation level, flavour profile, and caffeine content. Use this list to match the right tea to your time of day.
Tea Types | Processing (What makes it distinct) | Typical Flavour Profile | Caffeine (approx, per 250–300ml)* | Common moments |
|---|---|---|---|---|
Minimal (withered & dried) | Delicate, floral, honeyed | 15–30 mg | Late morning / Quiet focus | |
Unoxidised (heat-fixed) | Fresh, vegetal, nutty | 20–45 mg | Morning / Early afternoon | |
Gently “smothered” (light oxidation) | Mellow, rounded, soft sweetness | 30–45 mg | Afternoon (Softer lift) | |
Partial oxidation | Floral → toasted (varies widely) | 30–50 mg | Midday / Early PM | |
Fully oxidised | Malty, cocoa, brisk | 40–70 mg | Breakfast / Strong start | |
Fermented (piled/aged) | Smooth, earthy, grounding | 30–60 mg | After meals / Slower evenings |
*Caffeine varies with leaf amount and steep time. For the full comparison chart, see our guide to Tea and Caffeine Levels.

Chinese Tea Categories: The Six Types of Chinese Tea
One widely used way of grouping Chinese teas is the traditional six types: white, green, yellow, oolong, black, and dark tea. In Chinese tea traditions, these Chinese tea categories are defined primarily by processing (withering, heat-fixing, oxidation, and—only for some teas—post-fermentation), rather than by where the tea is grown.
Those Chinese tea categories are:
-
Green tea (绿茶) — heat-fixed to prevent oxidation; fresh, bright “leaf” character.
-
White tea (白茶) — minimally processed; withered and dried; soft, gentle aroma.
-
Yellow tea (黄茶) — lightly “sealed/rested” during processing for a rounder, mellower cup.
-
Oolong tea (乌龙 / 青茶) — partially oxidised; spans floral to roasted.
-
Black tea (红茶) — fully oxidised (note: called “Hong Cha” in Chinese due to the liquor colour).
-
Dark tea (黑茶) — post-fermented / aged styles; pu-erh sits here in the Chinese system.
Naming note (common confusion): what English speakers call “black tea” is usually Hong Cha (红茶 / red tea) in Chinese. Hei Cha (黑茶 / dark tea) refers specifically to post-fermented teas, not simply “a stronger black tea”.
