With the rapid growth in popularity of green, it is inevitable that sooner or later the question would arise: Does green tea have caffeine? The Chinese have been aware of the benefits of green tea for thousands of years, and it is fast catching on in the west as more and more research seems to back up the belief. But, with so many people worrying about the negative effects of caffeine, it is inevitable this question should have arisen.

So, Does Green Tea Have Caffeine Or Not?

The simple one word answer to the question does green tea have caffeine would have to be ‘yes’! However, if you ask exactly how much caffeine it contains it is not quite so easy to reach a definitive conclusion.

There are numerous factors which affect how much caffeine is contained in any cup of tea from the length of time the tea was allowed to brew to how hot the water is to how much tea is in the cup! Another factor may be where the tea was grown, which part of the plant was used…. I think you probably get my point – there is no definitive answer. However, having waded through a considerable amount of research and information it is possible to draw some conclusions. The range of figures I have found for individual drinks is quite large, so I have used an average to draw my conclusions and provide some sort of answer to the question does green tea have caffeine?

Does Green Tea Have Caffeine,  And If So How Much?

My research into the question does green tea have caffeine has concluded that yes, it does. In answer to the question how much and how does it compare we have the following averages:

• A cup of instant coffe contains 75-85mg caffeine
• A cup of filtered coffee contains 150mg caffeine
• A can of coke contains 34mg caffeine
• A cup of regular tea contains 40-50mg caffeine
• A cup of green tea contains 15-20mg caffeine

I would stress again that there are many factors which can affect these figures and different green teas will give different results.

It is possible to get green tea which has been decaffeinated, but the process tends to rob the tea of many of it’s beneficial qualities so whether decaff green tea is worth drinking is a moot point. It should be remembered that the reason green tea is so much better than black tea is because the leaves have not been oxidized and retain all their nutrients which include minerals, vitamins and antioxidants.

Conclusion: Does Green Tea Have Caffeine?

Don’t forget that caffeine is not all bad news as it stimulates the circulation and metabolism (read more about Green Tea benefits here: Does Green Tea Have Caffeine), and although not a proven fact, there is some indication that the caffeine in green tea is absorbed more slowly. (Personally I am not convinced that this isn’t simply down to the fact that there is less of it.)
