5. Conclusion

5.      Conclusions

5.1    Summary of findings
Based on the range of teas that we tested, the most common tea with the least caffeine that people drink is the organic peppermint tea and the tea with the most amount of tea is the black tea.

5.2    Practical Applications
As tea is a popular drink, many people may want to drink tea before they sleep at night. If the caffeine content in the tea is too high, it may keep people from sleeping.
As tea is very popular among many countries and there are many people that like drinking tea, this research will benefit them as some people may want to drink tea at night before sleeping but afraid that the caffeine content in the tea might keep them awake at night. To prevent them from keeping awake at night, they might be interested in finding out which tea contains the least amount of caffeine,so that they can still enjoy tea before bed. Also for people that may be allergic to too much caffeine, this will help them to avoid teas with high caffeine content and allow them to choose tea with low caffeine content.

5.3    Areas for further study
We could use a wider range of tea so we can have more results. We could also do this test for other drinks like coffee. We can then compare the tea and coffee and evaluate the different results. We can find other ways to extract caffeine from tea or see if can find other things we can extract from the tea. We can also compare the 1st brew to the 2nd brew and see if the caffeine in the tea is different, if the second brew might contain less caffeine or more, as some people like to reuse the tea bag.
