Yes, iced tea typically contains caffeine, especially if it’s made from black or green tea, with levels varying by type and brewing method.
Iced tea is a refreshing drink enjoyed worldwide, but many wonder about its caffeine content. The answer depends on the type of tea used and how it’s prepared. Most traditional iced teas contain caffeine unless specifically decaffeinated.
How Much Caffeine Is in Iced Tea?
The caffeine content in iced tea varies significantly based on several factors:
- Type of tea leaves used (black, green, white, or herbal)
- Brewing time and temperature
- Amount of tea leaves per serving
- Brand and preparation method
Caffeine Content by Tea Type
| Tea Type | Caffeine per 8 oz (mg) |
|---|---|
| Black Tea (iced) | 25-48 |
| Green Tea (iced) | 15-30 |
| White Tea (iced) | 10-15 |
| Herbal Tea (iced) | 0 |
Factors Affecting Caffeine Levels
Brewing Method
Hot-brewed iced tea (tea brewed hot then cooled) typically contains more caffeine than cold-brewed versions. The hotter water extracts more caffeine from tea leaves.
Tea Quality
Higher quality loose-leaf teas often contain more caffeine than tea bags. Younger tea leaves (like those used for white tea) contain more caffeine than mature leaves.
Decaffeinated Iced Tea Options
For those sensitive to caffeine, decaffeinated options are available. The decaffeination process removes about 97% of caffeine while preserving flavor. Popular methods include:
- Carbon dioxide processing
- Ethyl acetate method
- Water processing
Some brands like Lipton offer herbal iced tea varieties that are naturally caffeine-free.
Caffeine-Free Alternatives
If you’re looking to avoid caffeine completely, consider these options:
- Herbal iced teas (hibiscus, chamomile, mint)
- Fruit-infused waters
- Rooibos iced tea

Comparing Iced Tea to Other Beverages
Iced tea generally contains less caffeine than coffee but more than most sodas:
- Brewed coffee (8 oz): 95-200 mg
- Black iced tea (8 oz): 25-48 mg
- Cola (12 oz): 30-40 mg
Specialty Iced Teas
Bottled and Canned Iced Teas
Commercial iced teas like Lipton Iced Tea contain varying caffeine amounts. Always check labels as some brands offer “zero” caffeine options.
Homemade vs. Store-Bought
Homemade iced tea allows you to control caffeine content by adjusting brewing time and tea amount. Store-bought versions provide convenience but may contain additives.

- Pregnancy
- Heart conditions
- Caffeine sensitivity
- Sleep disorders
Always consult with a healthcare provider about your specific caffeine needs and limitations.
