A great coffee can still taste disappointing if the grind is wrong for the way you brew it. Too fine and the cup can become bitter, dry or heavy. Too coarse and it may taste weak, sharp or sour.
The good news is that grind size does not need to be complicated. Once you understand one simple idea, choosing the right grind becomes much easier.
Why grind size matters
Grinding coffee increases the surface area that water can reach. A finer grind exposes more coffee to the water and extracts flavour more quickly. A coarser grind exposes less surface area and extracts more slowly.
That is why fast brewing methods such as espresso need a fine grind, while longer brewing methods such as a plunger or French press work better with a coarse grind.
Which grind should you choose?
Espresso — Fine
Espresso pushes water through the coffee in a short amount of time, so it needs a fine grind. The coffee should feel fine between your fingers, but not quite powdery.
If your espresso runs very quickly and tastes thin or sour, try grinding finer. If it runs very slowly and tastes bitter or dry, try going slightly coarser.
Moka Pot — Fine to Medium-Fine
A moka pot generally works best slightly coarser than espresso. Too fine can restrict the flow and produce a harsh cup, while too coarse can leave the coffee tasting under-extracted.
A medium-fine grind gives you the rich, concentrated style a moka pot is known for without pushing extraction too far.
Filter and Pour Over — Medium
For most filter brewers and pour-over methods, start with a medium grind. Think of a texture similar to table salt.
If the brew drains too quickly and tastes light or sour, go a little finer. If it drains slowly and tastes bitter, go a little coarser.
Plunger / French Press — Coarse
Plunger coffee sits in contact with the water for several minutes, so a coarse grind is the better choice. It allows a slower extraction and also helps reduce fine sediment in the cup.
This is coarser than filter grind. If you are deciding between the two, choose Filter for drip or pour-over brewing and Plunger / French Press for immersion brewing.
Cold Brew — Coarse
Cold brew is usually steeped for many hours, so it also benefits from a coarse grind. A fine grind can make cold brew muddy and overly extracted.
A simple troubleshooting rule
If your coffee tastes sour, sharp or weak, it may be under-extracted. Try a slightly finer grind.
If it tastes bitter, dry or harsh, it may be over-extracted. Try a slightly coarser grind.
Grind size is only one part of brewing — dose, water temperature and brew time matter too — but changing the grind is often the easiest adjustment to make.
Whole bean or pre-ground?
If you have a good grinder at home, whole beans give you the most control and allow you to adjust your grind as you brew. But pre-ground coffee can still make an excellent cup when it is ground specifically for your brewing method and stored well.
When ordering Tableland Coffee, you can choose from Whole Bean, Espresso, Moka Pot, Filter, or Plunger / French Press, so the coffee arrives ready for the way you make it at home.
The easiest place to start
Do not worry about chasing an exact grinder number — every grinder is different. Start with the correct general grind range for your brewing method, taste the coffee, and make small adjustments from there.
That little adjustment can be the difference between a coffee that is simply okay and one that tastes balanced, sweet and full of flavour.
