Tea Guides

Our Dark Oolong Tea is for people who want a tea with body, depth, and something to think about. Heavily oxidized and roasted, it sits at the opposite end of the oolong range from the light, floral styles. It's closer to black tea, with a woody, stone fruit richness and a smooth finish that rewards slow drinking. If light teas seem too subtle, or you want a satisfying evening cup without the caffeine of a full black tea, try this one.

What Is Dark Oolong Tea?

Oolong covers a wide range of oxidation, from 15% (very green, floral, and light) to 85% (deeply oxidized, roasted, and rich). Our Dark Oolong sits toward the top of that range. It's more heavily oxidized and roasted than our Floral Oolong Tea, and has the deeper, more complex character that comes with that.

Roasting does two things. It drives off leftover moisture and grassy notes, and it creates Maillard reaction compounds, the same chemistry behind the flavours of roasted coffee, toast, and caramelised food. In Dark Oolong, that gives a warm, woody, caramelised depth that lighter teas don't have.

The tea is grown at high altitude in Nepal's Ilam district, and its natural sweetness, smooth finish, and low astringency survive under the roast. Thanks to the altitude, tannins are low enough that even after heavy processing the cup stays smooth.

Flavour Profile

Roasted, woody, and warm, with stone fruit (dried plum, apricot) under the roast and a smooth, slightly caramelised finish. The cup has weight and presence. As it cools, the roasted notes soften a little and the fruit sweetness underneath comes forward.

Despite its intensity, it has less caffeine than black tea. It satisfies without over-stimulating, which is one reason it works so well in the evening.

Who Is Dark Oolong Tea For?

• Coffee drinkers trying tea. Its dark, roasted character is the closest tea gets to the flavours coffee drinkers know.
• Evening tea drinkers. It has less caffeine than black tea (35 to 55mg against 40 to 70mg) and plenty of depth, so it makes a natural evening cup.
• Whisky and dark spirits drinkers. Its roasted, woody, fruity complexity fits the way people describe aged spirits.
• People who find light teas too subtle. Dark Oolong has unmistakable presence and is never boring.
• Meditation and slow rituals. It rewards attention and is a tea worth sitting with.

How to Brew Dark Oolong Tea

Water temperature: 95 to 100°C. Dark oolong can handle near-boiling water. Unlike light oolongs and green teas, it needs the higher temperature to bring out its roasted character fully.

How much leaf: 1 teaspoon (2 to 3g) per 250ml for Western style. For gongfu style, use 5 to 6g per 100ml with steeps of 45 to 60 seconds.

Steeping time: 3 minutes for Western style. Dark Oolong is more forgiving of long steeps than lighter teas; at 4 minutes you'll get a fuller, heavier cup, not a bitter one.

Straight or with a little milk: Dark Oolong is good without milk, since the roasted character is the point. Unlike light oolongs, though, where milk masks everything, it keeps its character with a little milk added. It's down to preference.

Re-steeping: Dark Oolong re-steeps well for 3 to 4 infusions. Later steeps are less roasted and show more of the stone fruit underneath, and each one is worth trying.

Dark Oolong vs. Floral Oolong

Our two oolongs sit at opposite ends of the range:

• Dark Oolong is heavily oxidized and roasted, with woody and stone fruit notes. It's rich and substantial, best in the evening or when you want depth.
• Floral Oolong Tea is lightly oxidized and aromatic, with jasmine and honey notes. It's light, sweet, and floral, best in the afternoon or when you want aromatic complexity.

Both are worth having, and together they show how wide the range of oolong is.

Frequently Asked Questions

Is Dark Oolong similar to roasted Taiwanese oolong (Dong Ding style)?

In character, yes. Both are heavily oxidized and roasted, with woody, caramelised notes and a smooth finish. The terroir differs (Himalayan against volcanic Taiwanese soil), but the processing and the resulting character are comparable, so Dong Ding fans will feel at home with our Dark Oolong.

How much caffeine does Dark Oolong have?

About 35 to 55mg per cup, between green and black tea. Despite its heavy character it has less caffeine than black tea, so most people can drink it in the evening.

Is it good for coffee drinkers?

Yes, more than any other tea we sell. Its roasted, dark, complex character is the closest match to the flavours coffee drinkers know, and it's a satisfying cup for people who find most teas too delicate or watery.

Can I drink it with milk?

Yes. With lighter teas, milk overwhelms the flavour, but Dark Oolong has enough character to stay interesting with a little milk. Try it both ways and see which you prefer.

Does Nepal Hills ship Dark Oolong to Canada?

Yes, Canada-wide from Peterborough, Ontario. Shipping is free on orders over $60 CAD, and most provinces get their orders within 3 to 7 business days.

The Bottom Line

Dark Oolong is the most substantial cup in our range: roasted, rich, woody, and smooth. Coffee drinkers reach for it in the evening, whisky lovers recognise its flavours, and anyone who finds ordinary tea too timid will take to it quickly.
