Most green tea is brewed badly: a quick dunk of a bag in boiling water. Here's how to get the flavour, and the good stuff, out of every leaf.
The short version: 2–3 g of leaf per 200 ml, water at 75–85°C, steep 3–4 minutes, then re-steep the same leaves. That's it.
The rest of this guide is the why, plus the myths worth dropping.
1. Start With Good Leaf
Whole, intact loose leaf gives you more flavour and more control than most tea bags. Bags usually hold small broken pieces ("fannings"). They brew fast but go bitter quickly, and you can't see what you're getting.
Look for leaves that are mostly whole, smell fresh and sweet-grassy, and come with a harvest date. Lots of dust and fragments usually means rough handling or old tea.
A note on "plant-based" bags: many silky pyramid bags are made from PLA, a plastic made from plants. It's still a plastic. Loose leaf in a stainless steel infuser avoids the question entirely.
2. Measure It
Use about 2–3 g per 200 ml cup. For most green teas that's a heaped teaspoon; for large, open leaves it may be two. Too little leaf gives you weak tea, however long you steep it.
Give the leaves room. They roughly double in size as they unfurl, so use a roomy infuser or a pot, not a tiny ball.
3. Water Temperature: For Taste
Myth: boiling water "burns" green tea and destroys its goodness. Reality: hotter water pulls more EGCG out of the leaf, along with more bitterness. Temperature is about taste.
Most green teas taste sweetest at 75–85°C. No temperature kettle? Let boiled water sit with the lid open for 3–5 minutes, or add a splash of cold water to the cup first.
If you like it hotter and don't mind the bite, go for it. You're not losing anything.
4. Steep Time: This Is Where the Good Stuff Is
Steep time matters more than temperature. L-theanine, the amino acid behind green tea's calm focus, comes out slowly.
| How you brew | L-theanine in the cup |
|---|---|
| A one-minute dunk | ~8 mg |
| 3–4 minutes, enough leaf | ~20 mg |
Same leaf, more than double the theanine. A well-brewed cup also has about 30–50 mg caffeine, roughly half a filter coffee.
5. Re-steep the Same Leaves
Good loose leaf is made for more than one cup. Pour fresh hot water over the same leaves and steep again, a little longer each time.
Here's what the second steep gives you, compared with the first:
- EGCG: roughly all of it again
- Caffeine: most of it (about 80%)
- L-theanine: about half
EGCG all, caffeine most, theanine half. Most good green teas give you two or three steeps, so one serve of leaf can carry you through the morning.
6. Use Fresh, Soft Water
Tea is 99% water, so the water matters. Fresh, filtered water gives a brighter, cleaner cup. Very hard water dulls the flavour and can leave a film on top.
7. Drink It Fresh
What actually degrades EGCG is time, not a few minutes in hot water. Tea left stewing on the bench for hours, or reheated again and again, loses both flavour and catechins. Brew it, drink it, brew again.
A squeeze of lemon helps keep EGCG stable. Milk is a matter of taste, but green tea is at its best without it.
8. Iced and Cold Brew
- Iced (most EGCG): brew hot at double strength, then pour over a glass full of ice.
- Cold brew (smoothest): leaves in cold water in the fridge for 6–12 hours. Sweeter and less bitter, with less caffeine. It also extracts less EGCG, so choose it for taste.
Quick Reference
| Tea | Water | Time |
|---|---|---|
| Green tea (loose leaf) | 75–85°C | 3–4 min, then re-steep |
| Matcha | 75–80°C | Whisk 1–2 g in 60–80 ml until frothy |
| Oolong | 85–95°C | 3–5 min, many re-steeps |
| Black tea | Just off the boil | 3–5 min |
| Green Goddess gem | Hot or cold, any temperature | Drop it in and it dissolves. No steeping. |
Brew it properly. Drink it daily.
A good cup takes four minutes. For the days you don't have four minutes, there's Green Goddess. And if you want leaf worth re-steeping, try Jade Mountain.
