Does Tea Have Caffeine? Everything You Need to Know
Tea is one of the world’s most popular beverages, enjoyed for its rich flavours and soothing qualities. However, a common question arises among tea drinkers: Does tea have caffeine? The answer is yes—but the amount varies depending on the type of tea and how it's brewed. This guide explores caffeine content in different teas, its effects, and how to choose the best tea for your lifestyle.
What Is Caffeine?
Caffeine is a natural stimulant found in tea, coffee, and some soft drinks. It works by stimulating the central nervous system, helping to improve alertness and reduce fatigue. While moderate caffeine intake can have benefits, understanding how much caffeine you consume is important for managing energy levels, sleep patterns, and overall health.
Does Tea Contain Caffeine?
Yes, all traditional teas derived from the Camellia sinensis plant—such as black, green, white, and oolong teas—contain caffeine. However, the caffeine levels vary depending on the tea type, processing methods, and brewing techniques.
Caffeine Levels in Different Types of Tea
-
Black Tea: Contains the highest caffeine levels, typically 40–70 mg per cup.
-
Green Tea: Offers moderate caffeine, around 20–45 mg per cup.
-
Oolong Tea: Falls between black and green tea, with 30–50 mg per cup.
-
White Tea: Has a lower caffeine content, about 15–30 mg per cup.
-
Herbal Teas: Naturally caffeine-free options, such as chamomile, peppermint, and rooibos.
Tea vs. Coffee: Caffeine Comparison
While tea contains caffeine, coffee generally has more. A standard cup of coffee has 95–200 mg of caffeine, significantly higher than most teas. Factors like bean type, brewing time, and preparation method influence caffeine levels in coffee, just as tea’s caffeine content varies based on leaf types and steeping time.
Factors Affecting Caffeine in Tea
-
Type of tea leaf: Younger leaves and buds contain more caffeine.
-
Brewing time and temperature: Longer steeping and hotter water extract more caffeine.
-
Serving size: Larger tea servings naturally have more caffeine.

FAQs
1. Can decaffeinated tea still have caffeine?
Yes, decaffeinated tea still contains trace amounts of caffeine, usually around 2–5 mg per cup. The decaffeination process removes most of the caffeine but not all. If you are highly sensitive to caffeine, consider opting for herbal teas, which are naturally caffeine-free.
2. Which tea has the least caffeine?
Herbal teas like chamomile, peppermint, and rooibos are completely caffeine-free. Among traditional teas, white tea generally has the lowest caffeine levels, though the exact amount depends on factors like leaf variety and brewing time. If you want minimal caffeine but still enjoy traditional tea, try brewing green or white tea for a shorter duration.
3. How can I reduce the caffeine in my tea?
There are several ways to lower the caffeine content in your tea. Steeping your tea for a shorter period and using slightly cooler water can help reduce caffeine extraction. You can also opt for decaffeinated versions of your favourite tea or blend traditional tea with herbal infusions to dilute the caffeine naturally. Try our caffeine free tea today.
