Three cups of coffee a day is already a part of my life running a wholesale and retail manual coffee grinder company in Hong Kong under the name of Fire Crystallization Company, HK.
Much of my time is spent studying about coffee equipment and DIY coffee just to have more fun to share with people or customer too. Still need to think how to modify my roaster and continue to update the information to share with all the coffee lovers in the world.
