How to Brew Green Tea (Sabz Chai): Temperature and Caffeine
If your sabz chai tastes bitter, the tea probably isn’t the problem. The kettle is. Green tea poured straight onto rolling-boiling water turns harsh and grassy, while the same leaves at around 80°C are smooth and sweetish. Here’s how to brew green tea Pakistani style, how much caffeine you’re getting, and why a cup of tea and a green tea capsule are not the same thing.
Quick facts
- Water temperature: 70 to 80°C, not boiling
- Amount: 1 level tsp (about 2 g) loose leaves per 200 to 250 ml
- Steep: 2 to 3 minutes
- Caffeine: usually somewhat less than black tea, but it varies
- Re-steep: good leaves give 2 or 3 cups

Sabz chai vs kahwa: not quite the same cup
Across Pakistan, “green tea” at home usually means loose sabz patti brewed with a crushed elaichi or two, served after a heavy meal. In Peshawar and much of Khyber Pakhtunkhwa, the qehwa poured endlessly in small cups is also green tea, often with cardamom. Kashmiri kahwa is a different, richer drink with saffron, cinnamon and almonds, and we’ve covered it separately in our Kashmiri kahwa recipe. This guide sticks to everyday sabz chai.
Buying green tea
Loose green tea should look like dry, dark green twisted leaves or rolled pellets, with a fresh, slightly grassy smell. Brown, dusty or hay-smelling tea is old. Green tea fades faster than black tea, so small packs you can use up in 2 to 3 months are better value than a big tin that goes flat. Tea bags are convenient but usually contain finer broken leaf that turns bitter quickly, so cut their steeping time to 1 to 2 minutes.
How to brew green tea at the right temperature
You don’t need a thermometer. Boiled water cools fast.
- Bring 250 ml fresh water to a boil in the kettle or a patili.
- Switch off and wait 2 to 3 minutes with the lid off. The water drops to roughly 80°C. Or add 50 ml cold water to 200 ml just-boiled water.
- Put 1 level tsp (about 2 g) loose green tea in a teapot or cup strainer. Add 1 lightly crushed green cardamom if you like.
- Pour the water over and steep 2 to 3 minutes. Not longer.
- Strain completely. Leaves left sitting in the pot keep turning the tea bitter.
- For a second cup, use the same leaves with water at the same temperature and steep 3 to 4 minutes.
Want it lighter? Use less tea, not less time. A squeeze of lemon added after straining is common and pleasant. A little honey is fine for adults and older children, but never honey for a baby under 1 year.
| Mistake | Result | Fix |
|---|---|---|
| Boiling water | Bitter, harsh | Cool 2 to 3 min |
| Steeping 5 to 10 min | Very astringent | 2 to 3 min, strain |
| Boiling leaves in the pot | Dark, bitter | Steep off the heat |
| Old, brown leaves | Flat, hay-like | Buy smaller packs |
Try this: after-dawat sabz chai
For a pot of 4 small cups: 700 ml water cooled to about 80°C, 3 level tsp green tea, 3 crushed green cardamoms and a thin strip of lemon peel. Steep 3 minutes, strain, and serve without sugar. It’s lighter than a second round of doodh patti after a wedding meal.
How much caffeine is in green tea?
Green tea does contain caffeine. People often assume it’s caffeine-free, which is wrong. Amounts depend on the leaf, how much you use, water temperature and steeping time, and hotter, longer brews extract more. As a broad guide, a cup of green tea usually has somewhat less caffeine than a cup of black tea, and much less than a strong coffee. Some green teas, especially matcha where you drink the powdered leaf itself, can carry as much or more.
If you’re counting caffeine, for pregnancy or sleep, treat a mug of green tea as roughly similar to a mug of ordinary tea. That’s the safe assumption. Health authorities generally advise pregnant women to stay under 200 mg of caffeine a day from all sources.
Green tea also contains the amino acid L-theanine, which is why many people describe its lift as calmer than coffee. That’s a common experience, not a promise.
In Pakhtun and Central Asian tradition, green qehwa follows almost every meal and every guest, and elders held that heavy, fatty food “needs” something light and warm afterwards. Unani writers classify tea generally as hot and dry. Many hakeems would add elaichi, which is traditionally counted a digestive, to balance it. This is custom and tradition, not a clinical claim.
Green tea on an empty stomach
Plenty of people drink green tea first thing, often because of weight-loss advice online. For some, that’s fine. For others, the tannins and caffeine on an empty stomach cause nausea, a queasy or burning feeling, or acidity. If that’s you:
- Have it after breakfast instead, or with a couple of dates or a slice of toast.
- Brew it lighter, cooler and shorter.
- If heartburn is a regular problem, see our acidity guide, and cut down caffeine overall.
Green tea is not a weight-loss drink. It has no meaningful effect on its own that replaces diet, activity and sleep. Enjoy it as a pleasant, low-calorie drink without sugar, which is benefit enough.
Green tea supplements vs tea: an important difference
A cup of brewed green tea and a green tea extract capsule are not the same thing. Extract supplements concentrate the catechins (mainly EGCG) far beyond what you’d get from drinking tea. There have been reports of liver injury linked to concentrated green tea extracts, especially when taken on an empty stomach or in weight-loss products, and European food safety authorities have raised concerns about high supplement doses of EGCG. Drinking green tea as a normal beverage has not raised the same concern.
So: drink the tea, skip the “fat burner” capsules, and don’t combine green tea extracts with other slimming products. If you already take one and notice dark urine, yellowing of the skin or eyes, unusual tiredness or pain in the upper right side of the tummy, stop it and see a doctor promptly.
Pregnancy and breastfeeding: count green tea toward the 200 mg daily caffeine limit, and avoid green tea extract supplements entirely.
Iron deficiency: like black tea, green tea reduces absorption of iron from plant foods. Drink it at least an hour away from meals and iron tablets.
Medicines: green tea can reduce absorption of some medicines, for example the beta-blocker nadolol, and caffeine interacts with others. If you’re on blood thinners like warfarin, keep your intake steady rather than suddenly drinking a lot. Ask your pharmacist about your own medicines.
Children: not suitable for young children because of caffeine.
Sleep, anxiety, palpitations: avoid it in the evening and cut down if you feel jittery. Chest pain or fainting needs medical attention.
Liver disease: avoid extract supplements and ask your doctor about tea.
Storing green tea
Air, heat, light and humidity fade green tea quickly. Keep it in a small airtight, opaque tin in a cool cupboard, away from the stove and spice smells. Don’t refrigerate an opened pack you use daily, because condensation forms each time you open it. Use within 2 to 3 months of opening.

Green tea questions
What temperature should water be for green tea?
About 70 to 80°C, not boiling. You don’t need a thermometer: boil the water, switch off and wait 2 to 3 minutes with the lid off, or add 50 ml cold water to 200 ml just-boiled water.
Why is my green tea bitter?
Usually the water was too hot, it steeped too long, you used too many leaves, or the leaves sat in the pot after brewing. Cool the water to around 80°C, steep 2 to 3 minutes and strain completely. Tea bags turn bitter faster, so give them just 1 to 2 minutes.
Does green tea help with weight loss?
Not in any meaningful way on its own. It can’t replace diet, activity and sleep, and no drink shifts belly fat by itself. What it does offer is a pleasant, near zero-calorie drink when taken without sugar, which is a fine swap for a sugary chai.
How much caffeine is in a cup of green tea?
It varies with the leaf and how you brew it, but it’s usually somewhat less than black tea and much less than strong coffee. Matcha can carry as much or more. If you’re counting caffeine, treat a mug of green tea like a mug of ordinary tea.
How many cups of green tea a day is safe?
For most healthy adults, a few cups of brewed green tea a day is a normal amount. The limit comes from caffeine, so count it alongside your doodh patti and coffee, cut back if you feel jittery or sleep badly, and avoid it in the evening.
Is it okay to drink green tea on an empty stomach?
Some people are fine with it. Others get nausea, a burning feeling or acidity from the tannins and caffeine. If that’s you, have it after breakfast or with a couple of dates, and brew it lighter, cooler and shorter.
Can I drink green tea while pregnant?
In moderation, counting it toward the 200 mg daily caffeine limit along with any other tea, coffee or cola. Avoid green tea extract supplements entirely. Your midwife or doctor can help you tally what fits.
Are green tea capsules the same as drinking green tea?
No. Extract capsules concentrate catechins far beyond a cup of tea, and they’ve been linked with liver injury, especially in weight-loss products taken on an empty stomach. Brewed tea hasn’t raised the same concern. If you take a capsule and notice dark urine, yellow eyes or upper right tummy pain, stop and see a doctor.
Can I add honey to green tea?
Yes, a little honey is fine for adults and older children, stirred in once the tea has cooled slightly. Never give honey to a baby under 1 year. A squeeze of lemon after straining is another common addition.
Does green tea affect iron absorption?
It does, like black tea: it reduces how much iron you absorb from plant foods. If you’re anaemic or pregnant, drink it at least an hour away from meals and iron tablets.
Can I reuse green tea leaves?
Good loose leaves give 2 or 3 cups. For the second cup use water at the same temperature and steep a little longer, 3 to 4 minutes. Broken leaf in tea bags doesn’t re-steep well.
Is sabz chai the same as kahwa?
Everyday sabz chai and Peshawari qehwa are both plain green tea, often with elaichi. Kashmiri kahwa is a richer drink with saffron, cinnamon and almonds, so it’s a different cup altogether.
Can I drink green tea with blood pressure or heart medicines?
Green tea can reduce the absorption of some medicines, such as the beta-blocker nadolol, and caffeine interacts with others. On warfarin, keep your intake steady rather than suddenly drinking a lot. Ask your pharmacist about your own medicines.
