How to Make Tea
By Mia Hartwell
Making tea looks like the simplest thing in the world. Hot water, a tea bag, done. And yet most of us have had a cup that came out bitter, or weak, or strangely flat, without ever knowing why. I certainly did for years. I would drop a bag in a mug, walk away, come back when I remembered, and wonder why the tea tasted like it was punishing me.
It turns out tea is fussy about exactly two things: how hot the water is and how long the leaves sit in it. Get those right and almost everything else is personal preference. Get them wrong and no amount of sugar or milk will save the cup. The good news is that both are easy to control once you know the numbers, and the numbers are not complicated.
This guide walks through the whole thing. The basic method that works for any tea, the exact water temperature and steeping time for each type, how to make iced tea and milk tea, and the handful of small mistakes that quietly ruin a good cup. By the end you will be able to make tea that actually tastes the way it is supposed to, every single time.
What You Need
You do not need special equipment. A kettle and a mug will make excellent tea. Everything beyond that just makes it a little easier or a little nicer.
- Tea. Loose leaf or bags. Loose leaf generally tastes better because the leaves are whole and have room to unfurl, but a good bag beats bad loose leaf every time.
- Fresh cold water. Start with cold water from the tap or filtered water. Water that has already been boiled once has lost dissolved oxygen, which makes tea taste dull and flat.
- A kettle. Any kettle works. A variable temperature electric kettle is a real luxury if you drink a lot of green tea, since it hits the exact temperature for you.
- An infuser or teapot. For loose leaf. Choose a roomy basket infuser rather than a cramped mesh ball, because leaves need space to expand.
- A timer. The most underrated tea tool there is. Your phone works fine.
How to Make Tea, Step by Step
This is the core method. It works for every type of tea, and the only thing that changes between them is the water temperature and the timer.
Heat fresh water to the right temperature
Fill the kettle with fresh cold water and heat it. Black and herbal teas want a full rolling boil at 212F. Green and white teas want noticeably cooler water, because boiling water scorches those delicate leaves and forces out bitterness within seconds. If you do not have a thermometer or a temperature kettle, boil the water and then let it sit off the heat for two to three minutes before pouring. That drops it roughly into green tea range.
Warm the pot or cup
Swirl a splash of hot water around the inside of your teapot or mug, then tip it out. This takes five seconds and stops a cold ceramic cup from pulling ten or fifteen degrees out of your water the instant you pour. It matters most in winter and most of all with green tea, where the temperature window is narrow.
Measure the tea
Use one teaspoon of loose leaf tea, or one tea bag, per eight ounce cup. If you like a stronger cup, add more leaf rather than more time. This is the single most useful trick in this guide. Extra leaf makes tea stronger and richer, while extra time makes it stronger and bitter, so they are not interchangeable.
Pour the water over the tea
Pour the hot water directly onto the leaves or the bag so everything tumbles and circulates. Agitation is how flavor gets extracted evenly. Dropping a bag into a cup of already still water gives you a strong bottom and a weak top, which is why that kind of tea always needs stirring.
Steep, covered, with a timer
Cover the mug with a saucer or put the lid on the pot. This keeps the heat in so the tea steeps at a steady temperature instead of cooling the whole time. Then set a timer and actually walk away. Judging steeping by eye does not work, because color develops much faster than flavor and a tea can look ready while still tasting thin.
Remove the leaves and serve
Take the bag or infuser out the moment the timer goes off. Do not squeeze the bag against the side of the cup. Squeezing wrings out concentrated tannins from the leaf pulp and adds a sharp, astringent edge to a cup that was otherwise perfect. Lift, drain for a second, discard, and add milk, sugar, honey, or lemon to taste.
Water Temperature and Steeping Time Chart
Save this. It is the whole guide in one table, and it is the difference between tea that tastes smooth and tea that tastes like it is fighting you.
| Tea | Water Temp | Steep Time | Notes |
|---|---|---|---|
| Black | 212F (full boil) | 3 to 5 min | Strong and malty, takes milk well |
| Green | 175F | 2 to 3 min | Delicate and grassy, burns easily |
| White | 185F | 4 to 5 min | Light and sweet, needs a longer soak |
| Oolong | 195F | 3 to 5 min | Re-steeps beautifully two or three times |
| Herbal | 212F (full boil) | 5 to 7 min | No real tea leaf, hard to over-steep |
| Rooibos | 212F (full boil) | 5 to 7 min | Naturally sweet, never turns bitter |
Making Each Type of Tea
Black tea
The most forgiving tea there is, and the one most people start with. Use fully boiling water and steep 3 to 5 minutes. Three minutes gives a brisk, lighter cup, five gives something dark and malty that stands up to milk. English Breakfast, Assam, and Ceylon all take milk well. Earl Grey and Darjeeling are usually better on their own, since milk flattens the bergamot and the floral notes. Past about five minutes black tea turns harsh, so this is one to time.
Green tea
This is where most people go wrong, and it is almost always the water. Boiling water on green tea leaves produces a bitter, spinach-like cup within about thirty seconds. Use water around 175F and steep only 2 to 3 minutes. Done properly, green tea is sweet, grassy, and light, with no bitterness at all. Good loose leaf green tea can be steeped a second and third time, and many people prefer the second cup. Matcha is green tea too, though it is a powdered whole leaf rather than an infusion, so it has its own method covered in our guide on how to make a matcha latte.
White tea
The least processed tea and the most subtle. Use water around 185F and steep 4 to 5 minutes. The longer time surprises people, but white tea leaves are barely handled, so they give up their flavor slowly. The result is delicate, slightly sweet, and floral. Do not add milk. It will bury everything that makes white tea worth drinking.
Oolong tea
Oolong sits between green and black, and it is the most rewarding tea to re-steep. Use water around 195F and steep 3 to 5 minutes. Then steep the same leaves again, and again. A good oolong changes character with each infusion, moving from bright and floral to deeper and toastier. If you have only ever used tea bags, a loose leaf oolong is the one worth trying.
Herbal tea and rooibos
Chamomile, peppermint, hibiscus, ginger, and rooibos are not technically tea at all, since they contain no leaves from the tea plant. That is good news for the cook, because without tannins they are nearly impossible to over-steep. Use fully boiling water and give them 5 to 7 minutes, or longer if you want it strong. They are naturally caffeine free, which makes them the obvious choice in the evening.
How to Make Iced Tea
The trick with iced tea is remembering that ice will dilute it. If you brew it at normal strength and pour it over ice, you get sad, watery tea. So brew it double strength, using two teaspoons of leaf or two bags per cup, with the same water temperature and steeping time as usual. Let it cool to room temperature, then pour it over a full glass of ice. The melt brings it right back to normal strength.
For cold brew iced tea, which is smoother and never bitter, put the leaves in cold water at about one teaspoon per cup and leave it in the fridge for 8 to 12 hours. There is no heat to pull out tannins, so it comes out remarkably sweet and mellow. Strain and serve. For sweet tea, stir the sugar in while the tea is still hot, since it will not dissolve properly once cold.
How to Make Milk Tea
Milk tea needs a stronger base than you would drink on its own, because the milk softens everything. Brew a strong black tea using a heaping teaspoon of leaf or two bags per cup, and steep toward the longer end at about 5 minutes. Assam and English Breakfast are ideal here. Then add warm milk to taste, roughly one part milk to three parts tea to start.
For a masala chai, simmer the tea directly in a mixture of half water and half milk with crushed cardamom, cinnamon, ginger, and cloves for about 5 minutes, then strain and sweeten. Simmering in milk is the one situation where the usual rules about gentle steeping do not apply, since the milk fat softens the tannins.
Common Mistakes to Avoid
If a cup of tea has ever tasted bitter, flat, or oddly thin, the reason is almost certainly on this list. Every one of these is a two second fix.
Pouring boiling water on green or white tea
This is the number one cause of bitter tea, and it is why so many people believe they simply do not like green tea. Green and white leaves are barely processed and extremely delicate. Water at a full boil scorches them on contact and forces out tannins within about thirty seconds, producing a harsh, astringent cup that tastes like boiled spinach.
Do this instead: Aim for about 175F for green tea and 185F for white. With no thermometer, boil the kettle and then let it stand off the heat for two to three minutes before pouring.
Squeezing the tea bag against the cup
It feels like you are extracting the last of the good stuff, but you are doing the opposite. The liquid trapped in soaked leaf pulp is heavily concentrated in tannins, the compounds responsible for dryness and bitterness. Pressing the bag releases all of them at once into a cup that was otherwise perfectly balanced.
Do this instead: Lift the bag out, let it drip on its own for a second or two, and discard it. If the tea is weaker than you like, use two bags next time rather than squeezing one.
Guessing the steeping time instead of timing it
Color develops much faster than flavor, so a tea can look dark and ready while still tasting thin, and it can look fine long after it has turned bitter. Judging by eye also means every cup is different. Most people who steep by feel drift steadily longer over time and slowly get used to increasingly harsh tea.
Do this instead: Set a timer on your phone. Three to five minutes for black, two to three for green, four to five for white, five to seven for herbal.
Reboiling the same water again and again
Fresh cold water holds dissolved oxygen, and that oxygen is what carries the aromatic compounds that make tea smell and taste alive. Every time water is boiled, more of that oxygen is driven off. Water that has been sitting in the kettle and reboiled three times produces a cup that tastes noticeably dull and flat, even when everything else is done right.
Do this instead: Empty the kettle and refill it with fresh cold water each time. It is the cheapest upgrade available to a cup of tea.
Cramming leaves into a tiny mesh ball infuser
Loose leaves need to expand to two or three times their dry size to release their flavor, and a small ball infuser physically prevents that. The leaves in the middle stay compressed and dry while only the outer layer brews, so you end up with a weak cup and a wad of wasted tea that never got to do its job.
Do this instead: Use a wide basket infuser, a teapot, or simply let the leaves float free in the pot and strain as you pour. Give them room.
Leaving the bag in the cup while you drink
Steeping does not stop when you decide the tea is ready. As long as the leaves are in the water they keep extracting, so a cup that was pleasant at minute four is genuinely unpleasant by minute ten. This is why the last third of a mug so often tastes worse than the first, and why people add sugar partway through.
Do this instead: Take the bag or infuser out the moment the timer goes off. If you want it to stay hot for longer, cover the mug instead of leaving the tea in.
Using water straight from the hot tap or a coffee machine
Hot tap water sits in a tank and picks up dissolved metals and sediment along the way, which gives tea a faintly metallic edge. Water from a coffee machine is worse, because the internal lines hold coffee oils that will quietly flavor everything that passes through them.
Do this instead: Always start with cold water and heat it in a kettle or a clean pot. If your tap water tastes of chlorine, use filtered.
Storing tea next to coffee and spices
Tea leaves are porous and absorb surrounding aromas with remarkable speed, which is exactly how scented teas like jasmine are made in the first place. Left in a cupboard beside coffee, curry powder, or an open bag of onions, plain tea will take on those smells within weeks and there is no way to reverse it.
Do this instead: Keep tea in an airtight, opaque container somewhere cool and dark, well away from anything strongly scented. Not the fridge, where condensation will get in.
How to Store Tea
Tea has four enemies: air, light, heat, and moisture. Keep it in an airtight, opaque container somewhere cool and dark, and keep it well away from coffee, spices, and anything else strongly scented, because tea leaves absorb surrounding smells with alarming enthusiasm. Do not store tea in the fridge, where condensation will get into it. Black tea holds up well for about two years, while green and white tea are best within six months to a year, since their fresher, more delicate flavors fade first.
The short version
Fresh cold water. Right temperature for the leaf, cooler for green and white, boiling for black and herbal. One teaspoon or one bag per cup. Cover it, time it, and take the leaves out without squeezing. That is genuinely all of it. Everything else in this guide is refinement on top of those five things.
Tea rewards a small amount of attention more than almost anything else you can make in a kitchen. Two minutes of care turns a mediocre cup into a genuinely good one, and once the numbers are in your head you will never really have to think about them again. Start with whatever tea is already in your cupboard, use the chart above, and taste the difference on the very first cup.

Frequently Asked Questions
How long should you steep tea?+
It depends on the leaf. Black tea needs 3 to 5 minutes, green tea 2 to 3 minutes, white tea 4 to 5 minutes, oolong 3 to 5 minutes, and herbal tea 5 to 7 minutes or longer. Steeping past those windows pulls out extra tannins, which is what makes tea taste bitter and dry rather than smooth.
Should you use boiling water for tea?+
Only for black and herbal tea. Fully boiling water at 212F is right for sturdy black leaves and herbal infusions, but it scorches delicate green and white tea and turns them bitter. For green tea aim for about 175F and for white tea about 185F. If you do not have a thermometer, boil the water and let it sit off the heat for two to three minutes.
Do you put milk in before or after the tea?+
Either works, and people have argued about it for well over a century. Adding milk after lets you see the color and control the amount, which is why most people do it that way now. Adding milk first was traditional because it kept delicate porcelain cups from cracking under hot tea. The flavor difference is very small.
How much tea do you use per cup?+
Use one teaspoon of loose leaf tea, or one tea bag, per eight ounce cup. For a larger mug or if you like it strong, use a heaping teaspoon. Adding more leaves makes tea stronger without making it bitter, while steeping longer makes it both stronger and more bitter, so adjust the amount of tea rather than the time.
Can you reuse tea bags or tea leaves?+
Loose leaf tea, especially oolong and good green tea, can be steeped two or three times and often tastes better on the second infusion. Tea bags hold small broken pieces that give up nearly all their flavor in the first steep, so a second cup tends to be weak and flat. Never save a used bag at room temperature for later, since damp leaves spoil quickly.
Why does my tea taste bitter?+
Almost always one of three things: the water was too hot for that type of tea, you steeped it too long, or you squeezed the tea bag. All three release excess tannins. Lower the water temperature for green and white tea, set a timer instead of guessing, and lift the bag out gently without pressing it against the cup.
