Quick answer: Tangerine pu-erh tea (also called xiao qing gan or 小青柑) is a traditional Chinese tea made by stuffing aged pu-erh leaves inside a hollowed-out green tangerine shell, then drying and ageing the two together for months or years. The result is a smooth, earthy tea with bright citrus notes — one of the most distinctive teas in the world, and a signature product of O2H TEA's O Collection.
What Is Tangerine Pu-erh Tea?
Tangerine pu-erh tea is a speciality Chinese tea that combines two ingredients: fermented pu-erh tea from Yunnan province and dried tangerine peel (known as chenpi in Chinese). The most prized version uses small green tangerines called xiao qing gan (小青柑), harvested before they fully ripen — when the peel is most aromatic and rich in essential oils.
Unlike ordinary flavoured teas where flavouring is added after production, tangerine pu-erh is a true fusion: the pu-erh leaves and tangerine shell age together, allowing the citrus oils and the earthy, fermented tea to slowly merge into a single, layered flavour profile. This process can take months to years, and like fine wine, the tea improves with age.
In Australia, tangerine pu-erh remains relatively unknown — most tea drinkers have never seen a whole tangerine stuffed with tea leaves. O2H TEA is one of the few Australian brands to offer a full xiao qing gan range, including Tangerine Pu-erh, Tangerine Oolong, Tangerine White Tea, and Tangerine Black Tea.
How Is Tangerine Pu-erh Tea Made?
The production of tangerine pu-erh tea is a multi-stage craft that requires patience and skill.
Step 1: Selecting the tangerines
Small green tangerines (xiao qing gan) are harvested from Xinhui, Guangdong province — the region famous for producing the highest quality chenpi in China. The tangerines are picked while still young and green, when the peel is thin, aromatic, and packed with volatile oils.
Step 2: Hollowing and filling
Each tangerine is carefully hollowed out by hand, removing the fruit flesh while keeping the shell intact. The hollow shell is then packed with aged, fermented pu-erh tea leaves — typically ripe (shou) pu-erh that has undergone the wodui (渥堆) fermentation process.
Step 3: Drying and ageing
The stuffed tangerines are sun-dried or low-temperature dried to preserve both the citrus oils and the tea's character. After drying, they continue to age — the flavours of the pu-erh and the tangerine peel slowly meld together over time. The longer the ageing, the smoother and more complex the flavour becomes.
What Does Tangerine Pu-erh Tea Taste Like?
Tangerine pu-erh tea has a distinctive flavour profile that sets it apart from any other tea:
- Aroma: A bright, sweet citrus fragrance layered over deep, earthy pu-erh notes
- Taste: Smooth and mellow, with a balance of tangerine sweetness and the rich, woody depth of aged pu-erh. No bitterness when brewed correctly.
- Colour: A clear, deep amber liquid
- Finish: A lingering sweetness with a gentle citrus aftertaste
The flavour is more approachable than plain pu-erh tea, making tangerine pu-erh an excellent entry point for tea drinkers who are curious about fermented Chinese teas but find straight pu-erh too earthy or intense.
How to Brew Tangerine Pu-erh Tea
Brewing tangerine pu-erh tea is simple, whether you use a whole xiao qing gan or break off a piece.
Method 1: Whole tangerine (recommended for beginners)
- Place one whole xiao qing gan in a teapot or large mug (300–500 ml)
- Rinse with hot water (95–100 °C) for 5 seconds, then discard the water
- Refill with hot water and steep for 3–5 minutes
- The same tangerine can be re-steeped 8–15 times — the flavour evolves with each steep
Method 2: Break and brew (stronger flavour)
- Break the tangerine shell into 2–3 pieces
- Place the pieces and loose pu-erh leaves into your teapot
- Rinse once, then steep for 2–3 minutes
- This method gives a stronger, more immediate flavour with more citrus intensity
Method 3: Gongfu style
- Use a gaiwan or small teapot (100–150 ml)
- Place a broken piece of xiao qing gan with some pu-erh leaves
- Rinse once, then steep for 10–15 seconds, gradually increasing steep time
- This reveals the most nuanced flavour progression across 10–20 steeps
Water temperature: Always use water at 95–100 °C. Tangerine pu-erh handles boiling water well — unlike green or white teas, there is no risk of burning the leaves.

Health Benefits of Tangerine Pu-erh Tea
Tangerine pu-erh tea combines the health properties of both fermented pu-erh and chenpi (aged tangerine peel). While we make no medical claims, these are the benefits commonly associated with the ingredients based on traditional Chinese medicine and preliminary research:
- Digestive support: Pu-erh tea has been consumed in China for centuries as an after-meal digestive aid. The fermentation process produces beneficial microorganisms that may support gut health.
- Vitamin C from the tangerine peel: The chenpi shell retains vitamin C and flavonoids, which are released during brewing.
- Antioxidants: Both pu-erh tea and tangerine peel contain antioxidant compounds.
- Gentle caffeine: Ripe pu-erh has moderate caffeine — less than black tea or coffee — making tangerine pu-erh suitable for afternoon and evening drinking.
Important note: Health claims about tea vary widely in scientific support. We encourage readers to enjoy tangerine pu-erh for its flavour and cultural significance, and to consult health professionals for specific health advice.
How to Store Tangerine Pu-erh Tea
Tangerine pu-erh tea can improve with age when stored correctly:
- Keep it dry: Store in an airtight container away from moisture
- Avoid strong odours: Tea absorbs surrounding smells easily
- Cool, dark location: Room temperature is fine — no need for refrigeration
- Allow some air exchange: Unlike green tea, pu-erh benefits from minimal air circulation during ageing. A ceramic jar with a loose lid works well.
Properly stored tangerine pu-erh can last for years, with the flavour becoming smoother and more complex over time. If the tea develops mould, visible discolouration, or an off-putting smell, it has been stored improperly and should be discarded.
When Is the Best Time to Drink Tangerine Pu-erh Tea?
Tangerine pu-erh tea is versatile enough for any time of day:
- Morning: A gentle energy lift without the jitters of coffee
- After meals: The traditional Chinese use — as a digestive aid after lunch or dinner
- Afternoon: A warming, flavourful break that pairs well with light snacks
- Winter evenings: The warming, citrus-sweet character makes it especially satisfying in cold weather
In Australia, tangerine pu-erh tea is particularly popular during the winter months (June–August), when its warming properties and rich flavour are most appreciated.
What Is the Difference Between Xiao Qing Gan and Chenpi Pu-erh?
This is a common question, and the answer comes down to the age of the tangerine:
- Xiao qing gan (小青柑): Uses small, unripe green tangerines. The peel is thin, intensely aromatic, and produces a brighter, more citrus-forward flavour.
- Da hong gan / chenpi pu-erh: Uses fully ripe, larger tangerines with thicker peel. The flavour is mellower, sweeter, and less sharp.
Both are legitimate styles of tangerine pu-erh tea. O2H TEA uses xiao qing gan for its Tangerine Serenade range because the young green tangerine delivers the most vibrant citrus character.

Frequently Asked Questions
What is tangerine pu-erh tea?
Tangerine pu-erh tea is a Chinese specialty tea made by stuffing aged, fermented pu-erh tea leaves inside a hollowed-out small green tangerine (xiao qing gan). The tea and tangerine shell are dried and aged together, creating a unique flavour that blends earthy pu-erh depth with bright citrus sweetness.
What does xiao qing gan mean?
Xiao qing gan (小青柑) translates to "small green tangerine" in Chinese. It refers to both the unripe tangerine fruit used in production and the finished tea product. In English, it is also called tangerine pu-erh tea, citrus pu-erh, or mandarin pu-erh.
How many times can you steep tangerine pu-erh tea?
A single xiao qing gan can be steeped 8 to 15 times, depending on brewing method and personal taste. The flavour changes with each steep — early steeps are more citrus-forward, while later steeps reveal more of the deep, earthy pu-erh character.
Is tangerine pu-erh tea good for digestion?
Pu-erh tea has been used as a digestive aid in Chinese culture for centuries, and the addition of chenpi (tangerine peel) is traditionally believed to support stomach comfort. However, these are traditional uses, not clinically proven medical claims.

How long does tangerine pu-erh tea last?
When stored properly (airtight, cool, dry, away from odours), tangerine pu-erh tea can last for years and actually improves with age. The flavour becomes smoother and more complex over time, similar to how fine wine develops with cellaring.
