Choosing Your Coffee Grinder

You can spend a fortune on a brewing machine, but it will only ever be as good as the grind it receives. A quality grinder is the primary tool for controlling the variables of your morning cup.

Before you start

Don't compromise on the mechanism

Avoid blade grinders; they create a mixture of boulders and dust that causes uneven extraction, leading to a cup that is simultaneously bitter and sour.

The key technique

Dialing in the grind size

Your grinder must allow you to adjust the distance between the burrs. The finer the setting, the longer the water stays in contact with the coffee; the coarser the setting, the faster the water flows through.

Step by step

The method.

  1. Select your burr type

    Choose ceramic burrs if you want durability and heat resistance, or steel burrs for a sharper, more precise cut that emphasizes clarity in the cup.

  2. Match the grinder to your method

    If you brew primarily with a French press, prioritize a grinder that maintains consistency at coarse settings. If you pull espresso, ensure the grinder has micro-adjustments to fine-tune the flow rate.

  3. Maintain the machine

    Coffee beans contain oils that go rancid over time. Remove the top burr once a month and clear out the chute with a stiff brush to prevent stale grounds from tainting your fresh roast.

Variations

Other turns to take.

Manual Grinders

Uses a hand-crank to rotate the burrs. They are quiet and compact, offering better value for money than electric versions because you aren't paying for a motor.

Electric Grinders

Best for those who brew multiple cups daily. Look for models with a 'stepped' adjustment for ease of use or 'stepless' for infinite precision.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Grind only what you need for the immediate brew to preserve volatile aromatics.

Tip

If your coffee tastes watery, move your grinder one click finer; if it tastes harsh and dry, move it one click coarser.

Tip

Listen to the grinder: a high-pitched whine often indicates the burrs are touching, which will cause damage.

Questions

The ones that keep coming up.

Why does my grinder produce so much dust?

This is called 'fines.' High-end grinders are engineered with better alignment to minimize this, but all burr grinders produce some amount of fine particles.

Does the motor speed matter?

Slower motors generate less heat during the grinding process. Heat can prematurely degrade the delicate oils in the coffee bean.
