Comparison of Grind Sizes

The table below highlights the differences between various grind sizes and their typical uses:

Grind Size	Texture	Common Use
Coarse	Chunky, similar to sea salt	French press, cold brew
Medium	Granulated, similar to sand	Drip coffee, pour-over
Fine	Similar to table salt	Espresso, Aeropress
Extra Fine	Powdery, flour-like texture	Turkish coffee

while you can use ground coffee in an espresso machine, the quality of the brew may be compromised without the appropriate grind size and specific coffee blends designed for espresso extraction. Adjusting your approach can help achieve a more satisfying espresso experience.

Understanding the Basics of Espresso Machines

Espresso machines are designed to produce coffee by forcing hot water through finely-ground coffee under pressure. The grinding process and the type of coffee used are critical to achieving the desired flavor and texture.
