The Best Guide to Grinding Coffee at Home
If we are going to make the best cup of coffee we can, one of the major lessons to learn is how to grind coffee. So we are going to need a good grinder.
I found this great video by wholelattelove.com that goes over everything that we need to know about grinders. Here are some snippets to help you figure out what kind is best for you. (scroll to the bottom for the entire video).
Reasons Not To Use a Blade Grinder
They don’t grind the coffee evenly, leaving small pieces and large chunks.
The large chunks don’t properly extract the flavor, but the small pieces do. You are essentially leaving flavor behind when you do this.
As he says the coffee will be unbalanced, weak and bitter at the same time.
Burr Grinders Are Your Best Bet
They come in different shapes, sizes and materials.
Burr grinders come in either flat or conical size. Which is better? This is highly debated.
Flat burrs tend to give a more consistent grind. Conical burr grinders grind faster. He mentions flat burr grinders are better for things like espresso, and conical burr grinders are better for things like pour over.
Burr size measured in milimetre sizes. Ranging from 40mm for home use to 83mm for commercial use. The higher the burr size, the higher the quality of the grind, and they tend to grind quicker.
Usually made of steel or ceramic. Sometimes even titanium, that will last a lifetime. Steel is the most common, will last a long time and tend to dissipate heat quicker than ceramic. Ceramic can be more brittle and break easier, although they stay sharper longer. Is one better than the other? They are both great choices.
If doing a lot of grinding, steel dissipates heat quicker, so that might be your best choice. It sounds to me like steel is durable enough, common enough, and given how we will be using it, this sounds like the best choice to me.
Two Basic Types
Stepped has clear stops and will stop on each step.
Stepless has no stops, allowing you to make finer, more precise decisions.
You don’t need stepless adjustment at home. Some have microadjustments within each step, so if you want to make espresso, you have the option.
Range from 100 to about 400 watts. The more watts there are, the longer it can grind for. As an example, 100 watts would grind for about 60 seconds then you would should wait about 10 minutes to grind again.
Obviously cheaper machines would have cheaper quality parts. The higher you go in price, the better quality of parts.
Other things to consider
The types of adjustments. Are there button adjustments, lever adjustments, etc…
Do the grinds go into a grind bin, is there a dosing lever that measures for you? Etc..

His “Jack of all trades” pick is the Baratza Vario
It can be easily adjusted, with micro adjustments, has a nice heavier duty conical burr grinder, and is a great little machine.
Dispenses into a grind bin or metal pour holder, and has long been known as a great machine for entry level into consumer espresso making.
He also reviews some machines for espresso, but since we aren’t really learning about I haven’t included that information here.
