Like Medium Fine grounds, Medium grounds are also perfect for Pour-over coffee and cone-shaped brewers like Hario V60, Kalita Wave, and AeroPress. It is also the most suitable grind size for Drip coffee machines.
ادامه مطلبTo achieve this type of fine grind, not just any coffee grinder will do. Not all coffee grinders are capable of grinding coffee beans to a fine or very fine consistency. The vast majority of coffee grinders, whether manual or electric, are only able to achieve relatively coarse grinds and nothing close to the grind size required for espresso.
