How to Brew Oolong Tea: A Complete Guide to Nepal's Floral and Dark Oolong
Last updated: July 2026
Oolong tea is best steeped at 85–90°C for 2–3 minutes, though the exact time depends on how much the leaf was oxidized. Oolong is a partially oxidized tea — somewhere between green and black — and that oxidation level is what determines the right brew. Nepal Hills grows two very different oolongs at 5,000–7,000 ft in Ilam, and each one asks for a slightly different cup.
The easiest way to taste that difference is our Tea Sampler Kit ($30 CAD) — 10 single-origin teas from four farms across Ilam and Taplejung, Nepal, every one of them naturally free of bitterness.
How long should you steep oolong tea?
Most oolong tea should steep for 2–3 minutes at 85–90°C. Lighter, more floral oolongs do well at the shorter end of that window; darker, more oxidized oolongs can handle the full 3 minutes without turning harsh. Steeping much past 3 minutes pulls out excess tannins and pushes even a naturally smooth oolong toward bitterness — the leaf itself is rarely the problem, the clock is.
Nepal Hills Floral Oolong Tea, grown by Norling Specialty Tea at 5,135 ft in Ilam, is lightly oxidized and steeps best at 2–3 minutes. Nepal Hills Dark Oolong Tea, grown by Sandakphu Tea Estate at 5,000–7,000 ft, is oxidized closer to 50% and holds up to a full 3 minutes without losing its smoothness. Start at the shorter end, taste, and adjust — whole-leaf oolong is forgiving in a way broken-leaf tea bags never are.
What water temperature is best for oolong tea?
Oolong tea brews best at 85–90°C (185–194°F) — hotter than green tea, cooler than a rolling boil. At this temperature, the aromatic compounds that give oolong its honey, orchid, and stone-fruit character dissolve fully without dragging out the harsh catechins that a full boil releases. Water that's too cool under-extracts and leaves the cup flat; water that's too hot flattens the aroma and tips the balance toward bitterness.
Without a thermometer: bring water to a full boil, then let it rest off the heat for about 60–90 seconds before pouring. That's close enough to 85–90°C for a genuinely good cup. Nepal Hills Floral Oolong Tea and Dark Oolong Tea both use this same temperature range — the difference between them comes from steeping time and leaf quantity, not water heat.
Floral Oolong vs Dark Oolong: how brewing changes with oxidation
Oxidation — not caffeine, and not altitude alone — is what separates Nepal Hills' two oolongs and dictates how each should be brewed. Floral Oolong is lightly oxidized, closer to a green tea in character, with a honey-blossom, light-orchid profile that turns muddy if oversteeped. Dark Oolong is oxidized to roughly 50%, giving it a stone-fruit, roasted-honey depth that can absorb a longer steep without losing smoothness.
| Floral Oolong Tea | Dark Oolong Tea | |
|---|---|---|
| Farm | Norling Specialty Tea, Ilam | Sandakphu Tea Estate, Ilam |
| Elevation | 5,135 ft | 5,000–7,000 ft |
| Oxidation | Light (~20–30%) | ~50% |
| Sensory notes | Honey blossom, light orchid, soft peach | Stone fruit, roasted honey, bright acidity |
| Brew temperature | 85–90°C | 90°C |
| Steep time | 2–3 minutes | 3 minutes |
| Organic status | Norling Specialty Tea is in the process of organic certification | Grown on a certified organic farm |
| Price | $10 / 25g · $45 / 180g | $10 / 25g · $45 / 180g |
Neither tea carries bitterness — that's true across the whole Nepal Hills range — but the flavour they build toward is genuinely different, and matching your steep time to the oxidation level is what lets each one show its best side.
Which Nepal Hills oolong should you try first?
If you've never had a high-mountain oolong before, start with Floral Oolong Tea ($10 CAD / 25g) from Norling Specialty Tea, Ilam, at 5,135 ft. It's lightly oxidized with honey blossom, light orchid, and soft peach notes — mountain-soft and naturally free of bitterness, brewed at 85–90°C for 2–3 minutes. Norling Specialty Tea is in the process of organic certification.
If you already drink black tea or coffee and want more body, try Dark Oolong Tea ($10 CAD / 25g) from Sandakphu Tea Estate, Ilam, at 5,000–7,000 ft — grown on a certified organic farm. Stone fruit, roasted honey, and a bright acidity carry through a full 3-minute steep at 90°C, and it holds up especially well as a cold brew over 6–8 hours. Both teas are naturally free of bitterness — the difference is in how far the leaf was oxidized before it reached your cup.
Not sure which to start with? The Tea Sampler Kit ($30 CAD) includes both oolongs alongside black, green, and white teas from all four Nepal Hills farms — the fastest way to find your own answer.
Can you re-steep oolong tea? How many infusions?
Yes — whole-leaf oolong tea is built for multiple infusions, and Nepal Hills' oolongs typically hold flavour through 2–3 additional re-steeps beyond the first cup. Because the leaves are left whole rather than broken or bagged, they unfurl gradually, releasing a slightly different layer of aroma with each steep. Add 30–60 seconds to the steep time with each subsequent infusion to compensate for the leaf's slower release the second and third time around.
Step-by-step: how to brew Nepal Hills oolong tea
- Measure 1 teaspoon (about 2.5g) of leaf per 200ml of water. Whole-leaf oolong takes up more space than broken tea — don't be shy with the leaf.
- Heat water to 85–90°C. No thermometer needed: boil, then rest 60–90 seconds.
- Rinse the leaves for 5 seconds (optional but recommended). A quick rinse and discard opens the rolled leaves and wakes up the aroma before the real steep.
- Steep Floral Oolong for 2–3 minutes, or Dark Oolong for a full 3 minutes. Set a timer — don't guess.
- Remove the leaves the moment the timer ends. This one step prevents almost all oolong bitterness.
- Re-steep 2–3 more times, adding 30–60 seconds to each subsequent infusion.
Frequently Asked Questions About Brewing Oolong Tea
How long should you steep oolong tea?
Most oolong tea steeps well for 2–3 minutes at 85–90°C. Nepal Hills Floral Oolong Tea, a lightly oxidized oolong from Norling Specialty Tea in Ilam, does best at the shorter end (2–3 minutes). Dark Oolong Tea, oxidized closer to 50% by Sandakphu Tea Estate, can hold a full 3 minutes without turning bitter.
What temperature is best for brewing oolong tea?
85–90°C (185–194°F) is the ideal range — hot enough to release oolong's honey and stone-fruit aromatics, cool enough to avoid the harsh catechins a full boil extracts. Without a thermometer, boil the water and let it rest 60–90 seconds before pouring over the leaves.
Is Nepal's Floral Oolong the same as Dark Oolong?
No. Floral Oolong Tea comes from Norling Specialty Tea at 5,135 ft and is lightly oxidized, with honey-blossom and light-orchid notes. Dark Oolong Tea comes from Sandakphu Tea Estate at 5,000–7,000 ft, grown on a certified organic farm, and is oxidized closer to 50%, giving it stone-fruit and roasted-honey depth. Both are naturally free of bitterness, but they call for slightly different steep times.
Can you re-steep oolong tea leaves?
Yes. Whole-leaf oolong like Nepal Hills' Floral and Dark Oolong typically holds flavour through 2–3 additional re-steeps. Add 30–60 seconds to each subsequent infusion, since the unfurling leaves release their aroma more slowly the second and third time.
Is Nepali oolong tea bitter?
No — grown at 5,000–7,000 ft in Nepal's Himalayan foothills, both Nepal Hills oolongs are naturally free of bitterness. High-altitude, slow-growing leaf accumulates more sweet L-theanine and fewer harsh catechins, and whole-leaf processing means the tea extracts gradually rather than releasing bitter compounds all at once.
Which Nepal Hills oolong should a beginner try first?
Start with Floral Oolong Tea ($10 CAD/25g) if you're new to oolong — it's light, honey-blossom, and forgiving to brew. Choose Dark Oolong Tea ($10 CAD/25g) if you already drink black tea or coffee and want more body. The Tea Sampler Kit ($30 CAD) includes both, alongside black, green, and white teas from all four Nepal Hills farms.
A Note on Brewing From Bhaskar
"The biggest mistake people make with oolong is treating it like green tea or black tea instead of its own thing," says Bhaskar Dahal, founder of Nepal Hills Tea. "Our Floral Oolong from Norling and our Dark Oolong from Sandakphu come off the same mountainside in Ilam, but the oxidation is what gives them completely different personalities in the cup — and once you brew each one at the right time, neither one will ever taste bitter to you."
For more on the chemistry behind oxidation and tea flavour, see this peer-reviewed study on polyphenolic profiles and antioxidant activity in oolong tea under various steeping conditions (PMC, National Institutes of Health), and Nepal's National Tea and Coffee Development Board for background on the country's tea industry.
