Caffeine Content in Tea and Coffee
The caffeine in tea and coffee can vary significantly depending on the type of drink, brewing method and cup size. While there is typically more caffeine in coffee, the difference in caffeine content can be quite low; for example, an 8 oz cup of drip-brewed coffee contains 95 mg of caffeine, compared to 47 mg in a similar-sized cup of brewed tea.
Different Types of Tea and Coffee
The caffeine content varies from one type of tea or coffee to another. Generally, dark roast coffee contains more caffeine than light roast coffee, around 90 to 150 mg per six ounce cup. Some espresso drinks like cappuccinos, for example, can contain up to 80 mg of caffeine per 2-ounce serving.
Tea also contains varying levels of caffeine; black tea generally contains the most caffeine, with around 50 mg of caffeine in a six-ounce cup, while green teas typically contain only 35 mg. White teas contain the least amount of caffeine, typically having only 20-30 mg of caffeine per cup.
Brewing Method and Cup Size
The type of drink and how much caffeine it contains isn’t the only factor to consider. The brewing method also makes a difference, as does cup size. Generally, the more time the tea or coffee is brewed, the more caffeine it will have. For example, a 4-minute brew for tea will yield more caffeine than a 1-minute brew.
In addition, a larger cup size will typically have more caffeine than a smaller cup. For example, an 8-ounce cup of drip-brewed coffee contains 95 mg of caffeine, compared to a 4-ounce cup, which contains 47 mg.
When trying to determine the difference in caffeine content between tea and coffee, it’s important to consider the type of drink, brewing method and cup size. Generally, coffee contains more caffeine than tea, but the difference can be minimal. Ultimately, the caffeine content can vary significantly depending on the type of tea or coffee and how it’s brewed.
- Different types of tea and coffee: Dark roast coffee typically contains 90 – 150 mg/six ounce cup, black tea 50 mg/six ounce cup, green tea contains 35 mg/six ounce cup and white tea contains 20-30 mg/cup.
- Brewing Method and Cup Size: The longer the tea or coffee is brewed, the more caffeine it contains. A larger cup of drip-brewed coffee typically contains more caffeine than a smaller cup, for example, 95 mg for an 8-ounce cup, compared to 47 mg for a 4-ounce cup.
- Final Thoughts: The type of tea or coffee and how it’s brewed affect the caffeine content. Generally, coffee contains more caffeine than tea, but variations exist depending on type and brewing.
