Which Grind Do I Need?

Every bag comes in three grinds. Here's how to pick the right one — and what goes wrong when you don't.

Grind size controls how fast water moves through coffee, and that controls everything you taste. A brewer that pushes water through in 25 seconds needs a completely different grind from one that steeps for four minutes. Get this wrong and no amount of good beans will save the cup.

The short answer: if you use a drip machine or a pour-over, choose Drip (Medium). If you pull shots, choose Espresso (Fine). If you own a grinder, choose Whole Bean and grind fresh.

Whole Bean

Unground

Ground coffee starts losing aromatics within minutes. If you have a burr grinder, whole bean is not a small upgrade — it's the single biggest difference between a decent cup and a good one. It's also the only way to get a proper coarse grind for French press or cold brew from us.

Use it for

  • Any method, if you own a grinder
  • French press and cold brew (grind coarse)
  • Anyone buying more than a week's worth at a time

Don't

  • You don't have a grinder

Drip (Medium)

Like coarse sand

The default for a reason. Medium grind suits the widest range of home equipment and is forgiving of small errors in ratio and temperature. If you're unsure which to order, this is the one.

Use it for

  • Automatic drip machines
  • Pour-over — V60, Chemex, Kalita
  • AeroPress
  • Most people, most of the time

Don't

  • Espresso machines
  • French press (it will silt)

Espresso (Fine)

Like table salt, almost powdery

Fine grind is built for the nine bars of pressure an espresso machine applies over 25–30 seconds. Put it in a drip machine and water can't pass through fast enough; you get an overflowing basket and a bitter, muddy cup.

Use it for

  • Espresso machines with a portafilter
  • Moka pot (stovetop)

Don't

  • Drip machines — it will overflow the basket
  • Pour-over — it will clog and stall
  • French press

Questions

What grind size do I need for a drip coffee maker?

A medium grind, roughly the texture of coarse sand. That's our Drip (Medium) option. Too fine and the basket overflows and the coffee turns bitter; too coarse and it runs through fast and tastes thin and sour.

Can I use espresso grind in a regular coffee maker?

No. Espresso grind is far too fine for a drip machine — water can't pass through it quickly enough, which causes the filter basket to overflow and over-extracts the coffee into bitterness. Use a medium grind for drip.

What grind is best for a French press?

A coarse grind, like rough sea salt. We don't sell a pre-ground coarse option because coarse grounds go stale especially fast, so buy whole bean and grind it yourself. A medium grind in a French press will pass through the mesh and leave silt in the cup.

Is whole bean actually better than pre-ground?

Yes, noticeably. Coffee loses its volatile aromatics within minutes of grinding, which is why pre-ground coffee tastes flatter even when it's the same beans from the same roast. If you own a burr grinder, whole bean is the better buy every time.

How do I know if my grind is wrong?

Taste tells you the direction. Bitter and harsh means the grind is too fine for your method — go coarser. Sour and thin means it's too coarse — go finer. Change one variable at a time, and change the grind before you change anything else.
