Below are different methods of brewing coffee beans with the appropriate ways to grind them:
- Automatic drip - The length of the drip cycle affects how fine you'll want to grind the beans. For example, when it's completed in less than four minutes, you'll want to grind your coffee finer than granulated sugar. If the cycle takes longer than six minutes, grind it coarser. For the most part, auto-drip should take 4 to 6 minutes and should be ground not too coarse and not too fine.
- French Press - Grind the coffee beans extremely coarse.
- Espresso Machines - Generally speaking, it should be ground really fine into a powder-like consistency. Similar to auto-drip, the best coffee grind is directly linked to the extraction time. One ounce of espresso will be extracted in approximately 25 to 30 seconds. If it takes less than that, grind your coffee even finer.
