THE FIRST SIP
Use a grind suited to your brewing method, then make small changes. Grinder numbers are not universal.
Why grind size matters
Grinding exposes more of the coffee to water. Particle size affects how coffee extracts and, in methods where water flows through a bed of grounds, how quickly it drains.
Fine grounds and coarse grounds behave differently. That is why the same bag of pre-ground coffee may work well in a drip machine and poorly in an espresso machine.
A starting point for each method
| Brewing method | Starting grind | What to know |
|---|---|---|
| Espresso | Fine | Needs a grinder with enough fine adjustment for your machine |
| Drip coffee | Medium to medium-fine | Basket shape and the brewer’s instructions matter |
| Pour-over | Medium-fine to medium-coarse | The dripper, filter, and recipe change the starting point |
| French press | Medium-coarse to coarse | Follow the recipe’s steep time and grind recommendation |
| Cold brew | Coarse | A common starting point for a long steep |
Use descriptions, not someone else’s dial number
A setting of 3 on one grinder may be very different from 3 on another. Start with your grinder or brewer’s guidance. For a built-in grinder, follow the machine’s instructions about when and how to adjust it.
Adjust one small step at a time
- Keep your coffee amount, water amount, and brewing method consistent while testing a grind change.
- If a brew seems weak and drains too quickly, a slightly finer grind may help. If it drains very slowly and tastes harsh, a slightly coarser grind may help.
- Taste is your guide, not a diagnosis on its own. Beans, water temperature, brewing time, and uneven extraction can also affect the result.
- Make one small adjustment, brew again, and note what changed.
If you buy pre-ground coffee
Tell the shop which brewer you use, or choose a grind labeled for that method. Buy amounts you can use comfortably and keep the container sealed.
If you grind at home, grind close to brewing time. A burr grinder is useful for more even particles and repeatable adjustments, especially when you want to fine-tune espresso.
