We’re here to tell you that size does matters when it comes to brewing a well balanced cup of coffee. So, java lover, are you using the proper coffee grind size for your brewing method?

The basic science of brewing coffee is; the relationship between the size of the grinds and the hot water running through the coffee grinds.

Drip coffee involves soaking coffee grinds in hot water in a paper filter that slowly drips into a carafe. Because the drip process is leisurely compared to espresso, it requires medium surface contact for the best flavor extraction. Medium grind size is also preferred when brewing coffee using the pour over method. *Coffee makers vary in process and technology so it is always best to understand your home brewing machine's recommendations and don't forget to do a descaling of your machine from time to time.
