About

Hey, welcome to my site. My name is Scarlett, the founder and writer of operator coffee. I love coffee in my whole life and always introduce nice coffee as well as related tools to people surrounding me. They are all happy with my honest advice.

Then I thought why not open a website to share my experience with more coffee lovers? Behind this site, there also have my closed friends who are so willing to join me after hearing this amazing idea. We are here to help you choose the best coffee makers, grinders, roasters, coffee beans and much more! With the unbiased guides and reviews, we believe you – our dear readers would get what you want.

Here is my personal email: [email protected]

I would like to hear from you.
