White Tea Caffeine:
Amounts by Type & Brewing Method
Last reviewed: July 2026 · By the White Tea Central editorial team
Quick answer
A 240 ml (8 oz) cup of white tea contains roughly 15–45 mg of caffeine — about a quarter to half of a cup of coffee (90–100 mg). The exact amount depends more on the leaf grade and your brewing choices than on the label “white tea”: bud-only Silver Needle (30–45 mg) delivers noticeably more caffeine than leafy Shou Mei (15–30 mg), and hotter water, longer steeps and more leaf all raise the number. Contrary to popular belief, white tea is not reliably lower in caffeine than green tea.
Caffeine by white tea variety
Estimates below assume a 240 ml cup. “Western” means a single 3–5 minute steep with about 2 g of leaf per 100 ml; “gongfu session” means the combined caffeine across a full session of short infusions with 4–5 g per 100 ml. Actual values vary with harvest, processing and water chemistry.
| Variety | Leaf grade | Western steep | Gongfu session | Notes |
|---|---|---|---|---|
| Silver Needle (Bai Hao Yin Zhen) | Buds only | 30–45 mg | 40–55 mg | Made entirely of young buds, which naturally hold the most caffeine on the plant. |
| White Peony (Bai Mu Dan) | Buds + young leaves | 25–40 mg | 35–50 mg | A mix of buds and first leaves lands it slightly below Silver Needle. |
| Gong Mei | Mature leaves, few buds | 18–32 mg | 25–40 mg | Later-harvest leaves carry less caffeine than buds. |
| Shou Mei | Mature leaves | 15–30 mg | 22–38 mg | The lowest-caffeine white tea in typical preparation. |
| Aged white tea (5+ years) | Varies | 15–35 mg | 20–40 mg | Caffeine is chemically stable; aging changes flavor far more than caffeine content. |
A counterintuitive rule of thumb: the more delicate the tea tastes, the more caffeine it may hold. Tea buds are the plant’s most caffeine-dense tissue — caffeine is part of its natural defense for new growth — so bud-only Silver Needle outranks the darker, bolder-tasting Shou Mei.
White tea vs. other drinks
| Beverage (240 ml) | Typical caffeine | Note |
|---|---|---|
| White tea | 15–45 mg | Varies widely by variety and brewing — see the table above |
| Green tea | 25–50 mg | Overlaps heavily with white tea |
| Oolong tea | 30–55 mg | Depends on oxidation level and leaf style |
| Black tea | 40–70 mg | Hotter water and longer steeps extract more |
| Brewed coffee | 90–100 mg | Roughly 2–4× a typical cup of white tea |
| Espresso (30 ml shot) | 60–65 mg | Concentrated but a smaller serving |
| Decaf coffee | 2–5 mg | Not fully caffeine-free |
Five factors that change how much caffeine ends up in your cup
“White tea” is not one caffeine number — it is a range you control. These are the variables that matter, in roughly descending order of impact:
Leaf grade
Buds contain more caffeine than mature leaves. Bud-only teas like Silver Needle sit at the top of the white-tea range; leafy Shou Mei sits at the bottom.
Water temperature
Caffeine dissolves faster in hotter water. Brewing at 80–85°C (the recommended range for white tea) extracts noticeably less caffeine than boiling water.
Steeping time
Extraction rises steeply in the first 2–3 minutes and keeps climbing more slowly after that. A 5-minute Western steep pulls out most of the available caffeine.
Leaf-to-water ratio
More leaf per ml of water means more total caffeine in the cup. Gongfu brewing uses 2–3× the leaf of Western brewing, offset by much shorter steeps.
Number of infusions
Caffeine is front-loaded: the first infusion releases the largest share, and each re-steep yields less. By the fourth or fifth gongfu infusion, very little remains.
Want less caffeine? Brew for it
- Pick a leafy variety. Shou Mei or Gong Mei over Silver Needle cuts the baseline roughly in half.
- Brew cooler. Stay at 80–85 °C instead of near-boiling water.
- Steep shorter. Two minutes instead of five extracts meaningfully less caffeine — and white tea stays sweet rather than turning astringent.
- Skip the myth. A quick “decaffeinating rinse” does not work — it removes around 10% of caffeine at most while washing away aroma.
- Drink later infusions. In a gongfu session, most caffeine comes out early; sharing the first infusion and savoring rounds three onward is a gentler evening option.

How much caffeine is in white tea?
A typical 240 ml (8 oz) cup of white tea contains roughly 15–45 mg of caffeine, depending on the variety and how it is brewed. Bud-only teas like Silver Needle sit at the high end (30–45 mg), while leafy varieties like Shou Mei sit at the low end (15–30 mg). For comparison, a cup of brewed coffee contains about 90–100 mg.
Does white tea have less caffeine than green tea?
Not reliably. The two ranges overlap heavily: white tea typically delivers 15–45 mg per cup and green tea 25–50 mg. Laboratory analyses have found some white teas — especially bud-heavy ones like Silver Needle — contain as much or more caffeine than green teas. The 'white tea is lowest in caffeine' claim is a common myth; brewing parameters matter more than tea category.
Which white tea has the least caffeine?
Shou Mei, made from mature leaves harvested later in the season, typically delivers the least caffeine per cup (about 15–30 mg brewed Western style). Buds hold more caffeine than mature leaves, so bud-only Silver Needle is usually the strongest white tea despite its delicate taste.
Does gongfu brewing extract more caffeine than Western brewing?
Per infusion, no — the 20–30 second steeps extract only a fraction of the leaf's caffeine. But a full gongfu session of 5 or more infusions on the same leaves usually extracts more total caffeine than a single Western steep, because the higher leaf-to-water ratio means more caffeine is available overall.
Can I make white tea caffeine-free by rinsing the leaves?
No. The popular '30-second rinse removes most caffeine' tip is a myth: studies show a short rinse removes only around 10 percent or less of the caffeine. If you need to avoid caffeine, choose an herbal infusion instead, or opt for a leafy white tea brewed cool and short to minimize (not eliminate) caffeine.
Does aged white tea have less caffeine?
Aging changes a white tea's flavor and color dramatically, but caffeine is a chemically stable compound, so the caffeine content of aged white tea remains close to that of the fresh tea it was made from. Choose aged tea for its honeyed, woody character — not as a low-caffeine option.
