Here is the short answer. Brew Yunnan dianhong black tea with water at 90 to 95°C (194 to 203°F), not a rolling boil. In a mug or small teapot, use one 3 gram sachet or 3 grams of loose leaf per 250 ml of water and steep for 2 to 3 minutes. The same leaves will give you a second cup. In a gaiwan, use 5 to 6 grams per 120 ml, start at 10 seconds, and expect 3 to 5 infusions. The full parameters, including the jasmine and rose versions, are in the table below.
Dianhong brewing parameters at a glance
| Method | Leaf | Water | Temperature | First steep | Total infusions |
|---|---|---|---|---|---|
| Mug or small teapot | 3 g (one sachet) | 250 ml | 90 to 95°C | 2 to 3 minutes | 2 |
| Gaiwan (gongfu) | 5 to 6 g | 120 ml | 90 to 95°C | 10 seconds, then add 5 to 10 seconds each round | 3 to 5 |
| Jasmine or rose dianhong, any vessel | Same as above | Same as above | 85 to 90°C | Shorten by about 30 seconds (mug) or keep at 10 seconds (gaiwan) | Same as above |
| Cold brew | 3 g per 300 ml | Room temperature or fridge | Cold | 8 to 12 hours in the fridge | 1 |
If you searched for this page, those numbers are probably what you came for. The rest of this guide explains why they work, how to adjust them for the scented versions and for milk tea, and what dianhong actually is. Our own Ancient Black Tea is a Yunnan dianhong from old tea trees, sold in 3 gram sachets, so every example below is measured against a real bag you can hold.
Why 90 to 95°C instead of boiling water
Most Western tea guides tell you to pour fully boiling water on any black tea. Dianhong is more forgiving than a green tea, but the teas made from Yunnan's large leaf varietal carry a lot of honey and malt sweetness, and water straight off the boil pushes the brew toward tannic bitterness before that sweetness has a chance to show. Letting the kettle rest for about a minute after boiling lands you in the 90 to 95°C range without a thermometer. If your kettle has temperature control, set it to 95°C and forget about it.
There is one situation where full boiling water makes sense, and that is milk tea. More on that below.
Brewing dianhong in a mug or small teapot, step by step
This is the method most of our customers use on a weekday, and it is the one most brewing guides skip past. It works with a sachet or with loose leaf in an infuser.
- Boil your water and let it rest for about one minute. You are aiming for 90 to 95°C.
- Use 3 grams per 250 ml. One Tastea sachet is exactly this dose. For a large 350 ml mug, the same sachet still works, and the cup will simply be a little lighter. If you prefer it stronger, steep longer rather than hotter.
- Steep 2 to 3 minutes, then remove the leaves. Start tasting at 2 minutes. Dianhong turns a deep amber quickly, so judge by taste, not by color. Removing the sachet matters, because leaves left sitting in the mug keep extracting and turn the last third of your cup bitter.
- Resteep once. Give the second infusion 3 to 4 minutes. In our own testing notes for this tea, two mug infusions is the honest count, and the pattern matches what we measured across methods in our guide to how many times you can steep a tea. A third mug steep is usually thin.
That works out to two full cups from one $2.99 sachet, which is a useful number to keep in mind the next time a coffee shop charges you six dollars for one.
Gongfu brewing, briefly
If you own a gaiwan, dianhong rewards the small vessel treatment: 5 to 6 grams in 120 ml at 90 to 95°C, a 10 second first infusion, and 5 to 10 seconds added to each round after that, for 3 to 5 infusions in total. Watching the flavor move from honey toward malt and dried fruit across those rounds is the point of brewing it this way. We wrote a complete walkthrough of the equipment, the pouring technique, and the timing in our gongfu brewing guide for beginners, so this article will not repeat it.
Brewing the jasmine and rose versions
This is the section almost no brewing guide covers, because most shops only sell unscented dianhong. Our Ancient Black Tea comes in three versions: Original, Jasmine, and Rose. The base leaf is the same, so the parameters above are your starting point, with two adjustments.
Drop the temperature to 85 to 90°C. Floral aromatics are more volatile than the malt and honey notes of the base tea. Water that is slightly cooler keeps the jasmine or rose character in the cup instead of sending it out of the mug as steam in the first thirty seconds.
Shorten the first steep. In a mug, start tasting at about 90 seconds instead of 2 minutes. The floral layer comes out ahead of the tannin, so the tea reaches its balance point sooner. If you steep the scented versions as long and as hot as the original, the result is a cup where the base tea overwhelms exactly the thing you chose that version for.
If you are deciding between the three, Original shows the Yunnan leaf most clearly, Jasmine is the most approachable for people who usually drink green tea, and Rose is the one we see chosen most often as a gift.
Dianhong for milk tea and cold brew
Dianhong's malt and honey profile is sturdy enough to carry milk, which is not true of most Chinese teas. For milk tea, break the gentle temperature rule on purpose: use boiling water, double the leaf to about 6 grams per 250 ml, and steep 4 to 5 minutes. You want an overstrength base, because milk will soften both the body and the tannin. Add warm milk to taste, and sugar if you like. The Original version works best here; the scented versions lose their floral point under milk.
For cold brew, put 3 grams in 300 ml of cold water and leave it in the fridge for 8 to 12 hours. Cold water extracts the sweetness and almost none of the bitterness, so the result is a smooth, honeyed tea that needs nothing added. This is the lowest effort method on this page, and in summer it is the one we would point a complete beginner to first.
Five mistakes that ruin a good dianhong
- Judging strength by color. Dianhong brews dark within the first minute. The color arrives long before the flavor peaks, and long before the bitterness does. Trust the clock and your tongue.
- Leaving the leaves in the mug. A sachet is easy to pull out. Pull it out.
- Boiling water on the jasmine and rose versions. As above, the aroma you paid for evaporates first.
- Throwing the leaves away after one steep. The second infusion is not a leftover. In gongfu brewing, the second and third rounds are usually the best ones.
- Storing the tea next to the stove. Heat, light, and kitchen smells all flatten the leaf. A sealed sachet in a cool cupboard keeps its character; an opened bag by the window does not.
What you are actually drinking
Dianhong simply means Yunnan red tea. Dian is the classical short name for Yunnan province, and hong cha, red tea, is what China calls the category the West labels black tea. It is a young style by Chinese standards, first produced in the late 1930s, but Yunnan itself is the oldest tea landscape on earth, home to tea trees that have been growing for centuries.
That is the meaning of the word Ancient in our Ancient Black Tea. The leaf comes from old tea trees deep in the Yunnan mountains rather than from young hedge rows on a plantation. Older trees root deeper, grow slower, and give a thicker, sweeter liquor, which is where the honey, malt, and dried fruit character in your cup comes from. When a guide tells you dianhong tastes like malt and honey, this leaf is the version of that claim you can actually taste.
Not sure dianhong is your tea? Ask the AI guide
Every brewing guide assumes you have already chosen your tea. If you have not, Tastea has a shortcut that traditional tea shops do not: an AI tea guide on our site that asks a few questions about what you already drink, whether you take coffee with milk, and how you feel about bitterness, then points you to the tea that fits. It takes about a minute, and it will tell you honestly if you are more of a green tea or oolong person than a black tea person.
If you would rather taste your way to the answer, the Discovery Trio tasting set ($24.99) is the sampler we built for exactly this: three sachets each of this dianhong, Da Hong Pao oolong, and West Lake Dragon Well green tea, nine cups across three provinces, with a brewing card in the box.
Ready to brew? A single sachet of Ancient Black Tea is $2.99 in Original, Jasmine, or Rose. If it is a gift, the AI customized gift box ($66.66) lets the guide build a box around what the recipient actually drinks.
