The site seems easy enough to navigate and the messaging is straight forward. I don't know enough about the tea market to know how big the niche is (although there is a ton of search volume on Google Trends for tea related keywords, which is a good indicator).

Regarding monetization- I noticed you are using adsense. Your content is so ultra targeted that you would probably make a lot more money with affiliate or revshare deals than with adsense. Here is a list of tea related affiliate programs (I have never used any of these and am not affiliated with them in any way, just thought it would be a good starting point).
