90% of Coffee Aroma Is Decided the Moment You Grind

Starter Tools and Budget

All you really need are two things: a grinder and fresh beans. Starting with a hand grinder lets you grind anywhere without electricity, and it also makes it easier to learn grind-size adjustment by feel.

An initial budget of 60,000~100,000 won is enough. The difficulty is two out of five stars; if you can cook instant noodles, you can get the hang of it in a week.

Finding the Right Grind Size

  • Pour-over: about the texture of coarse salt. When you rub the grounds between your fingers, the particles should feel clearly distinct.
  • French press: coarser, around the texture of cracked black pepper.
  • Espresso: very fine, just slightly coarser than flour.
  • If the grind is too fine, the coffee turns bitter and muddy; if it is too coarse, it tastes weak and sharply acidic.

Your First Cup with Freshly Ground Beans

Brew one cup and you will immediately notice how much the flavor changes with grind size. If it tastes too acidic, grind a little finer next time; if it tastes bitter and muddy, grind a little coarser.

💡
Note: Store beans in an airtight container in a cool, dark place, not in the refrigerator. The refrigerator absorbs moisture and odors, which actually ruins the aroma.
