The three main types of coffee grinders are blade, flat plate, and conical. Conical burr grinders are the original type of grinders and use burrs placed at a near vertical orientation which spin at a low speed so there’s no burn taste. These provide the most consistent coarse grounds used in French press or pour over coffee but will also make good medium to fine grinds as well
Next, you have blade grinders which use sharp cutting blades spinning at very high speeds to cut and chop coffee beans to grounds. The least expensive option, they work best for medium type grounds ideal for drip machines and percolators. For most coffee making applications, a blade grinder is really all you need. Because of their operating speed, they can sometimes burn the beans and slightly alter the taste of your coffee.
Lastly, you have flat plate burr grinders which turn slower than blade grinders so there’s less of a chance the coffee will burn. They use horizontal burrs on a flat plate (hence the name) which do a credible grinding job for all coffee grinds, but they excel at finer grinds like espresso and Turkish blends.
For the purpose of this list, we’re concentrating on electrically powered grinders because they grind larger quantities of beans faster and easier, especially when you’re making more than one cup of coffee. Every one of these grinders will be easy to take apart and clean which is helpful if a bean gets caught in the mechanism, the blades gum up from very oily or flavored beans, or if a foreign object accidentally gets into the grinder.
Each pick will also have at least five grind selections unlike some basic coffee grinders that have no selection capability where it’s almost impossible to get consistent grounds from one brewing session to the next. These selections will grind at least eight cups of coffee at one time, giving you enough grounds to fuel any coffee making pot that you plan on using. Lastly, each of these machines will come with a limited manufacturer’s one year warranty, unless otherwise mentioned in the description.
