Why is the level of coffee grind so important?
The level of coffee grind has a huge impact on its flavor. It determines how long the water is in contact with the coffee during brewing, and thus how many aromas and flavor compounds are extracted.
If the grind is too fine, it causes over-extraction, which can make the coffee bitter, astringent, and heavy.
If the grind is too coarse, it leads to under-extraction, and the brew will be watery, sour, and lacking in depth of flavor.
Each brewing method requires a properly selected grind size to bring out the full aroma, achieve the right consistency, and ensure a balanced flavor.
