Burr vs Blade Coffee Grinder: What a Burr Grinder Is and Why It Matters
A blade grinder chops beans with a spinning blade, producing an uneven mix of dust and chunks that brews unevenly. A burr grinder crushes beans between two abrasive surfaces to a uniform size you can dial in — which is why it makes better, more consistent coffee and is the only type suitable for espresso or pour-over. Blade grinders are cheaper; burr grinders are the upgrade that actually changes the cup.

Grind size sets how fast water pulls flavor out of coffee, so each brew method needs its own grind: fine for espresso, medium for drip and pour-over, coarse for French press, extra-coarse for cold brew.

Here is what each dollar actually changes in the cup — and where the smart money stops.
