How Much Caffeine Is in Darjeeling Tea? A Flush-by-Flush Guide
Someone asks this question in our inbox almost every week, usually right after they have discovered that Darjeeling is not one tea but dozens, each picked at a different point in the growing season. "How much caffeine is actually in this?" is a fair question, and the honest answer is: it depends on which Darjeeling you are holding, and how you brew it.
The Short Answer
A standard 200 ml cup of brewed Darjeeling black tea contains roughly 40 to 50 mg of caffeine, compared to around 95 mg in a similar cup of drip coffee. That puts Darjeeling at a moderate caffeine level: lower than coffee, but generally higher than green tea and well above any caffeine-free herbal blend. The exact number moves depending on flush, leaf grade, water temperature, and steep time, all of which are covered below.
What "Flush" Means and Why It Changes Caffeine Levels
Darjeeling tea is harvested in flushes, which are distinct picking periods across the growing year, each producing a noticeably different leaf.
- First flush (March to April): The youngest, most tender leaves of the season. Light in body, floral, and slightly lower in caffeine because the leaf mass is smaller and less mature.
- Second flush (May to June): Fuller leaves with the classic muscatel character Darjeeling is known for. Generally the highest caffeine of the three main flushes, since more mature leaf tissue tends to carry a denser concentration of caffeine.
- Autumn flush (October to November): Mellower, darker, and moderate in caffeine, sitting between the other two.
Younger leaves and tips (the unopened leaf buds) generally carry more caffeine per gram than older, larger leaves, which is part of why leaf grade matters as much as flush timing.
Caffeine by Flush and Grade
| Darjeeling Type | Approx. Caffeine per 200 ml Cup | Flavor Character |
|---|---|---|
| First flush (whole leaf) | 30 to 40 mg | Light, floral, slightly astringent |
| Second flush (whole leaf) | 45 to 55 mg | Full-bodied, muscatel, fruity |
| Autumn flush | 35 to 45 mg | Mellow, woody, smooth |
| Broken leaf or fannings grade | 10 to 15% higher than equivalent whole leaf | Brews faster and stronger due to greater surface area |
These figures are general ranges drawn from tea industry sources and should be read as estimates rather than exact lab values, since caffeine content varies from garden to garden and even harvest to harvest.
How Brewing Method Changes the Number in Your Cup
The leaf itself only sets the ceiling. What actually ends up in your cup depends heavily on how you brew it.
Water Temperature
Caffeine is highly soluble in hot water. Brewing closer to 90 to 95 degrees Celsius extracts caffeine faster and more completely than a cooler steep. This is one reason cold brewed Darjeeling generally delivers noticeably less caffeine per serving than a hot-steeped cup made with the same amount of leaf.
Steep Time
Most caffeine releases within the first 2 to 3 minutes of steeping. A quick 90-second infusion pulls meaningfully less caffeine than a full 5-minute steep, even with identical leaf and water temperature.
Leaf-to-Water Ratio
More leaf per cup means more caffeine, in a fairly direct relationship. A heaping teaspoon steeped in 200 ml will run noticeably higher in caffeine than a light, level teaspoon in the same volume of water.
A Practical Guide to Adjusting Your Caffeine Intake
If you want a gentler cup, steep for 2 minutes instead of 5, use slightly cooler water around 85 degrees Celsius, and favor a lighter first flush leaf over a robust second flush. If you want the fuller lift, go the opposite direction: full 4 to 5 minute steep, near-boiling water, and a second flush or broken grade leaf.
It is worth noting that steeping longer does not just add caffeine, it also pulls more tannins into the cup, which is why an over-steeped Darjeeling often tastes more bitter as well as more stimulating. The two effects run together more than most people realize.
Frequently Asked Questions
Is Darjeeling tea lower in caffeine than coffee?
Yes, generally. A cup of Darjeeling typically contains 30 to 55 mg of caffeine, compared to roughly 95 mg in an equivalent cup of drip coffee.
Which has more caffeine, first flush or second flush Darjeeling?
Second flush tends to run slightly higher, largely due to the fuller, more mature leaf used at that point in the season.
Does cold brewing reduce caffeine content?
Yes, in most cases. Cold water extracts caffeine more slowly than hot water, so a cold brewed cup generally carries less caffeine than a hot-steeped cup made with the same leaf quantity, even over a longer steep time.
Can I decaffeinate Darjeeling myself at home?
A rough home method is a 30-second hot water rinse of the leaves before the real steep, since a large share of caffeine releases in the first moments of contact with hot water. This will not fully decaffeinate the tea, but it noticeably softens the caffeine content.
Is Darjeeling a good choice for an afternoon cup?
For most people, a lighter first flush Darjeeling steeped briefly makes a reasonable afternoon option, well below the caffeine load of a mid-afternoon coffee. Anyone especially sensitive to caffeine may still want to keep it earlier in the day.
