Best Tea for Sleep: Low-Caffeine Options That Actually Work
A warm drink before bed is one of the oldest pieces of sleep advice there is. Tea is the obvious choice, but teas differ a lot when it comes to winding down, and the main reason is caffeine. Some teas have several times as much as others.
Below: which teas have the least caffeine, how to brew them so they stimulate you as little as possible, and why the bedtime ritual may matter as much as the tea. We'll also explain why the Nepali white teas we buy from Ilam suit evenings so well.
Does tea have caffeine? (Yes, but some have far less)
Every tea made from the Camellia sinensis plant contains caffeine: black, green, oolong, and white. How much depends on the type of tea, how it was processed, and how you brew it.
Here are the typical ranges:
| Tea Type | Caffeine per Cup (approx.) | vs. Coffee |
|---|---|---|
| White tea | 15 to 30 mg | About 1/4 of a coffee |
| Green tea | 25 to 45 mg | About 1/3 of a coffee |
| Oolong tea | 30 to 60 mg | About 1/3 to 1/2 of a coffee |
| Black tea | 40 to 70 mg | About 1/2 of a coffee |
| Coffee | 80 to 120 mg | n/a |
White tea is the least processed true tea: young buds and leaves that are simply dried. It has the least caffeine and the gentlest flavour, which makes it the natural evening choice.
The best teas for sleep
1. White tea: lowest caffeine, softest flavour
Among true teas, white tea has the least caffeine. At 15 to 30 mg a cup, it's about a quarter of what's in a coffee. It's also rich in L-theanine, an amino acid that keeps you calm and alert and may soften the effect of what caffeine there is.
The taste helps too. White teas are light, floral, and gently sweet, with nothing harsh or astringent and essentially no bitterness. They fit the slower pace you want before sleep.
We carry two white teas, both grown at 5,000 to 7,000 ft in Ilam by our farm partner Farmers Tea Co.
Floral White Tea ($10/25g) tastes of spring blossom and soft rose, with a velvety finish. It's our most popular evening tea. Its floral notes come out best at lower brewing temperatures, which also pull out less caffeine.
Fresh White Tea ($10/25g) has notes of wildflower, morning dew, and crisp cucumber. It's minimal and clean, a bit like spring water with a hint of flowers.
2. Light green tea: low caffeine, smooth and easy
Green tea has a little more caffeine than white, but it's still gentle, especially brewed cooler and for less time. Our Organic Light Green Tea ($20/50g) from Ilam is grown on our farm partner's certified organic land (packaging certification is in progress). It's smooth and one of the least stimulating teas we sell.
3. Light oolong: in between, if you handle caffeine well
Our Floral Oolong ($10/25g) falls between green and black, with notes of honey blossom, orchid, and soft peach. If you drink coffee regularly and have built up a tolerance, a light oolong in the early evening may still let you wind down.
How to brew white tea with less caffeine
How you brew changes how much caffeine ends up in the cup. Cooler water and shorter steeps pull out less caffeine and keep the flavour.
Use water at 70 to 75°C (158 to 167°F). Never pour boiling water on white tea; high heat damages the delicate amino acids and extracts more caffeine. Steep for 2 to 3 minutes and no longer. A first steep at 70°C for 2 minutes has noticeably less caffeine than a 4-minute steep at 85°C.
Use 2 to 3 grams of leaf per 250ml. More leaf with a shorter steep gives you a fuller flavour and less caffeine than less leaf steeped longer. You can also re-steep the leaves: each steep has less caffeine than the one before, so a third or fourth steep of white tea is very gentle.
No thermometer? Bring water to a full boil, pour it into your mug, and wait 10 to 12 minutes. It will drop to about 70°C.
The ritual matters as much as the tea
Making and drinking a warm cup of tea is itself a signal to sleep. It's slow, it's deliberate, and it keeps you off screens. Sleep research keeps finding that a regular wind-down routine is one of the most effective ways to sleep better without medication.
A warm cup of white tea 30 to 60 minutes before bed raises your core temperature and then lets it fall, which mimics the natural dip before sleep. It gives your hands and eyes something to do besides look at a screen. And over time, your body learns to treat it as a bedtime cue.
The trick is picking a tea that doesn't work against you: low in caffeine, and without bitterness that leaves you uncomfortable.
What about herbal tea?
Herbal "teas" like chamomile, valerian root, and passionflower are technically tisanes. They aren't made from the tea plant, so they have no caffeine at all. If you're very sensitive to caffeine or want to be certain, they're worth a look.
If you enjoy the flavour of real tea, though, white tea from high-altitude Nepal is about as close as you can get to no stimulation while still having something interesting in the cup.
What makes our white teas different
Our white teas come from Farmers Tea Co in Ilam, a certified organic farm in Nepal's Himalayan foothills at 5,000 to 7,000 ft. The plants grow slowly in the cool, thin air and develop natural sweetness and complexity without the tannins that cause bitterness.
So the tea needs no milk, sugar, or sweetener. You can drink it plain and quietly, just as it is, which is part of why it works so well in the evening.

Frequently Asked Questions
What is the best tea to drink before bed?
White tea, because it has the least caffeine of any true tea: roughly 15 to 30 mg a cup, compared with 80 to 120 mg in coffee. It also has L-theanine, which calms you without making you drowsy. Brew it cooler (70 to 75°C) for 2 to 3 minutes to cut the caffeine further. If you want no caffeine at all, choose an herbal tea like chamomile.
Does white tea keep you awake?
White tea has some caffeine (roughly 15 to 30 mg a cup), so it's mildly stimulating. Most people who aren't very sensitive to caffeine can drink it in the early evening without it affecting their sleep, and cooler water and shorter steeps reduce the caffeine further. If you are very sensitive, stick to herbal tea after 5pm.
Which tea has the least caffeine?
Among true teas, white tea has the least, typically 15 to 30 mg a cup. Next come green tea at 25 to 45 mg, oolong at 30 to 60 mg, and black tea at 40 to 70 mg. Within each type, brewing makes a big difference: cooler water and shorter steeps extract less caffeine.
Is it good to drink tea before bed?
A warm, low-caffeine tea like white tea can help you sleep in a few ways. The warm drink raises and then lowers your body temperature, the ritual of making it becomes a regular wind-down cue, and the L-theanine in white tea is calming. Pick a white or very light green tea and brew it cooler to keep the caffeine down.
What makes Nepali white tea good for evenings?
White teas grown at 5,000 to 7,000 ft in Ilam grow slowly in cool mountain air, which makes them naturally sweet. They need no milk or sugar, have no bitterness, and make a gentle, floral cup that suits an evening ritual.
Can I cold brew white tea overnight?
Yes. Steep 3 to 4g in 500ml of cold filtered water in the fridge for 8 to 12 hours. Cold water extracts caffeine more slowly, so the result is naturally sweeter and lower in caffeine than hot-brewed tea, and the floral and fruity notes come through clearly.
