Ever made a coffee that tasted... off? Too bitter. Too sour. Or just plain sad and watery?
Chances are, it wasn't the beans. It was the grind.
Grind size is the quiet hero of good coffee. Nobody talks about it at parties. But it makes or breaks your morning cup. So let's sort it out, once and for all.
Why Grind Size Even Matters
Think of coffee grounds like tea leaves.
- Too fine: Water rushes through too slowly, pulling out all the sour, sharp, and over-extracted flavours.
- Too coarse: Water rushes through too fast and can't grab enough flavour before it's gone. You end up with something that tastes like brown water. Sad.
Different brew methods need different grind sizes because they spend different amounts of time in contact with water. Quick brews need a finer grind. Slow brews want it coarser. That's really the whole secret.

A Few Honest Tips
Taste is the real chart. These are starting points, not laws. If your pour-over tastes sour, go finer. If it's bitter, go coarser. Your tongue knows more than any chart.
- Buy whole beans, grind fresh. Pre-ground coffee starts losing its flavour the moment it's ground. It's a bit like buying a bunch of flowers that are already wilting.
- A cheap grinder still beats no grinder. Start somewhere. Upgrade later if you fall in love with the ritual.
- When in doubt, go coarser. Too fine is usually the mistake that makes coffee bitter and harsh. Coarser is the safer, gentler choice while you're learning.
The Takeaway
Good coffee isn't about fancy gear or secret tricks. It's mostly about matching your grind to your method, and giving it a fair go.
So next time your coffee tastes a bit meh, don't blame the beans just yet. Have a look at your grind first. It's usually the real culprit, quietly hiding in plain sight.
