ABOUT OUR OOLONG TEAS
Semi-oxidised classics from China & Java
At DieTees you'll find premium oolong tea in verified quality: from the creamy China Milky Oolong with its characteristic buttery taste to the fruity Bio China Jade Oolong and the aromatic Bio Java Jade Oolong – each variety with its own character. Oolong (Chinese Wū Lóng, "black dragon") is a semi-oxidised type of tea that sits between green and black tea: less oxidised than black tea, more processed than green tea. The result is a layered, complex aroma. High-quality oolongs can be infused 3–5 times – each infusion brings a new flavour profile.
Our loose-leaf oolong tea is carefully processed and offers an intense, layered aroma — no tea-bag wrapper, in full leaf quality. Browse our selection above or discover more organic teas in our range.
Reading tip: Learn all about the tradition, processing, varieties and correct preparation of oolong in our oolong guide.
VARIETY OVERVIEW
What types of oolong are there?
Oolong teas can be broadly classified by degree of oxidation and region of origin — each variety has its own character:
- Milky Oolong (China) — lightly oxidised, creamy and buttery in aroma. Sweet and mild, the classic for beginners.
- Jade Oolong (China & Java) — lightly oxidised (10–30 %), fruity and fresh, with floral notes. Often a greenish, jade-coloured infusion.
- Heavily oxidised oolongs (e.g. Da Hong Pao, Wu Yi) — 50–80 % oxidised, roasted and full-bodied, with a darker infusion, closer to black tea.
- Flavoured oolongs — refined with peach, vanilla or blossoms, premium blends for special moments.
Looking for milder teas from Camellia sinensis? Take a look at our green tea category with unoxidised classics, or the more delicate white tea category. For stronger classics we recommend our black tea selection. Caffeine-free alternatives can be found in the herbal tea category.

FREQUENTLY ASKED QUESTIONS
Answers about oolong tea
What is oolong tea?
Oolong (Chinese Wū Lóng, black dragon) is a semi-oxidised type of tea that sits between green tea (unoxidised) and black tea (fully oxidised). Depending on the degree of oxidation (10–80 %), a very wide spectrum of taste and aroma profiles emerges – from floral and fresh to roasted and full-bodied.
How is oolong tea prepared?
Let the water cool to 90–95 °C (a little hotter than for green tea), use 1 tsp per 250 ml and steep for 2–3 minutes. High-quality oolongs can be infused 3–5 times – shorten the steeping time slightly for the 2nd and 3rd infusion, then lengthen it again for the 4th and 5th.
How much caffeine does oolong tea contain?
Oolong tea contains caffeine – about 30–50 mg per cup (250 ml), depending on the variety and steeping time. That is similar to or slightly more than green tea, but less than black tea or coffee.
What is Milky Oolong?
Milky Oolong is a lightly oxidised oolong that develops a creamy, buttery aroma through a special processing method or through cultivar-specific characteristics. The distinctive milky-sweet taste gave it its name – even though it contains no milk.
What is the difference between oolong and green tea?
The main difference is oxidation: green tea is heated immediately after harvest (steamed or pan-fired), so no oxidation takes place. Oolong, by contrast, is semi-oxidised – the tea leaves are allowed to oxidise partially. The result: oolong has more complex aromas and is usually rounder in taste. More in our green tea guide.
