Home Coffee Grinding
Grind your beans immediately before brewing to preserve volatile oils and aromatics. A consistent grind size is the deciding factor in how much flavor you extract from the bean, requiring a burr grinder rather than a blade chopper to ensure every particle offers the same surface area for water contact.
Consistency is the only metric that matters.
Avoid blade grinders, which shatter beans into a mix of dust and boulders that cause uneven extraction. You want a consistent, uniform particle size throughout.

Crushing versus Chopping
Burr grinders use two abrasive surfaces to crush beans into uniform shapes. Blade grinders rely on speed, resulting in inconsistent grounds that yield both bitter and sour notes simultaneously.
The method.
Select your setting
Match the setting to your brew method: coarse like sea salt for French Press, medium like sand for drip coffee, or fine like powdered sugar for espresso.
Weigh the beans
Use a scale to weigh beans before grinding rather than measuring by volume. A standard ratio is 1:16, or 1 gram of coffee for every 16 grams of water.
Grind in bursts
If using a manual hand grinder, keep a steady, rhythmic pace. If using an electric burr grinder, engage the motor just long enough to process the dose to avoid heating the beans.
Transfer immediately
Ground coffee begins to oxidize and lose intensity within minutes. Pour the grounds into your filter or brewer right away.
Other turns to take.
Coarse
Used for cold brew or French press, where water sits with the grounds for several minutes.
Medium-Fine
The standard for pour-over methods, allowing for balanced flow and extraction time.
Extra-Fine
Required for espresso or Turkish coffee to create enough resistance against pressurized water.
When it doesn't go to plan.
Clean the burrs with a stiff brush once a month to remove trapped oils that can go rancid and taint fresh beans.
If your coffee tastes overly bitter, coarsen the grind setting slightly; if it tastes thin or sour, move toward a finer setting.
Never store pre-ground coffee in the freezer; the condensation creates moisture that accelerates staling.
The ones that keep coming up.
Can I use my food processor to grind beans?
No. It will result in an erratic mix of chunks and fine powder, making it impossible to achieve a balanced cup of coffee.
Does the temperature of the grinder matter?
Yes. Friction generates heat, which can start to cook the oils in the coffee before it even hits the water. Keep your grinding sessions short.
