1. Can you drink too much green tea?
The short answer is yes. Green tea is associated with a lot of health benefits and contains a wide range of healthy ingredients. But some of these ingredients like polyphenols and caffeine can be potentially dangerous if consumed in large quantities. Although it’s quite difficult to reach those levels by drinking home-brewed green tea this doesn’t mean you shouldn’t be careful. Use common sense and listen to your body when drinking a lot of green tea. And just to be clear, one or two, three or even four cups of green tea a day won't be bad for you under normal circumstances.

2. I found some very affordable green teas like Matcha and Gyokuro in a tea store close to us. Why are they so cheap and should I buy them?
First of all, there are different types and grades of green tea. Different production methods and different regions where the tea comes from also make a difference. Gyokuro and Matcha in particular are rare and high-quality teas. Like for fine wines or other delicacies, there is a large demand but only a limited supply. Cultivating and making superior green tea requires a lot of time and labor. In addition, only the finest and youngest leaves are good enough for superior green tea. Even in Japan, these teas are expensive and if the tea is very affordable it could mean the quality might be compromised.
3. Why is the shelf life of green tea so short compared to other teas?
Green tea leaves are more delicate than other tea types. In fact, less oxidized teas like green tea or white tea and in some cases oolong tea have a shorter shelf life. The tea starts to lose scent, color and flavor fast if stored improperly. Green tea in particular is appreciated for its freshness, so if you really want to enjoy it, use it within 6 to 7 months of purchasing. However, if stored properly, it can be good for more than a year.
There are a few things you can do to prolong the shelf life of your favorite tea:
- Always store the tea in a dark and cool environment
- Keep the tea in a sealed clean, odor-free, airtight container.
- Container should be as small as possible to keep the amount of air in contact with the leaves to a minimum.
- Do not open packaging too often to minimize its exposure to the elements.
- Do not use wet spoons to scoop out tea leaves.
