You do not strictly need one, but a burr grinder is the biggest upgrade for home coffee after fresh beans. It grinds the beans to an even size, and even grounds brew a cleaner cup.
A blade grinder is fine in a few cases, listed below. For most people who drink coffee every day, a burr grinder is worth the money.
Blade versus burr
A blade grinder works like a small blender. A spinning blade smashes the beans. It chops some into dust and leaves others in big chunks, and the result depends on how long you hold the button.
A burr grinder crushes beans between two rough surfaces set a fixed distance apart. You choose the gap, and the beans pass through until they are the size you set. The pieces come out close to the same size.
Why even size matters
Hot water pulls flavor out of coffee in order. Small grounds give up everything fast, including the bitter and harsh parts. Large chunks give up too little and taste sour or thin.
A blade grinder gives you both in one cup. That is why the coffee can taste bitter and weak at the same time. A burr grinder narrows the range, so the water extracts more evenly.
What about pre ground coffee?
Pre ground coffee is the easiest option, and it is not a bad choice for drip. The cost is freshness. Ground coffee has far more surface exposed to air, so the aroma fades in days. Whole beans stay good for weeks.
Pre ground is also a fixed size. If you want to try a French press, a pour over or an AeroPress, one bag will not suit all of them.
When a blade grinder is fine
- You brew a drip pot, and you like the taste you get now.
- You also use it for spices, and you want one tool.
- Your budget is tight, and a blade grinder lets you start buying whole beans today.
A few habits help a blade grinder: use short pulses, shake the grinder between pulses and stop sooner for coarse grinds. You will not match a burr, but you will do better than a long hold.
When to get a burr grinder
- You make French press, pour over, AeroPress or moka pot. All are sensitive to grind size.
- You buy good beans and want the money to show up in the cup.
- You want to try espresso. That needs a more precise grinder than the one below.
One entry level option
This conical burr grinder has 40 grind settings, which is enough range for drip, pour over and French press. It is a common first burr grinder. It is not the grinder for espresso, because the steps between settings are too wide for fine tuning. Skip it if you only drink instant or pre ground coffee and plan to stay that way. We have not tested it, so this is based on its specs and owner reports.
