Grinder settings vary by brand, but here’s a cheat sheet. For a standard drip machine, aim for a setting between 12 and 18 on a scale of 1 to 40 (common on models like Baratza). On a less technical grinder, look for the “drip” icon—it’s there for a reason.

Still unsure? Try the pinch test: take a bit of ground coffee between your fingers. If it feels gritty but not powdery, you’re in the zone. If it’s sticky or clumps, grind coarser.
Pro tip: Brew a test batch with a 1:16 coffee-to-water ratio. If the coffee tastes hollow or metallic, your grind is too coarse. If it’s harsh or bitter, go coarser. Your palate is the ultimate guide.
The Paper Filter Factor
Not all drip setups are created equal. If you use paper filters, they trap oils and fines, so a slightly finer medium grind can work beautifully. With metal mesh filters, you’ll want a coarser medium to avoid sediment and bitterness.
Here’s a cultural nugget: In Japan, many drip coffee enthusiasts use thick paper filters for a clean cup, grinding a notch finer than Western standards. It’s a subtle shift that highlights the bean’s origin notes.
Experiment with your filter type and adjust accordingly—your morning cup will thank you.
