Why you need a coffee grinder
After coffee is ground, it starts losing compounds that contribute flavor within a few minutes. Making the best-tasting, freshest coffee requires grinding the beans just before brewing. You can get a coffee grinder at home for under $50 and use your current coffee maker to get better coffee. Read on for information about the best coffee grinders for home use.

Blade GrindersBlade grinders use a thin steel blade to grind coffee beans. This is considered the lowest quality of coffee grinder for a few reasons. One is that the small surface of the blade can heat up, causing scorching of the coffee grounds. This results in an undesirable burned flavor. Another issue with blade grinders is that they slice the beans rather than crushing them, resulting in a range of fine and course grounds. It is harder to control the coarseness of the grounds using a blade grinder.

Disc Burr GrindersDisc burr grinders are the most affordable of the burr grinders and produce good results. The disc burr grinder mechanism uses a disc with raised surfaces that are used to slice the beans. The pitch of the raised surfaces can be used to control the coarseness of the grounds.

This grinding mechanism uses a cone shaped burr for the surface to crush the coffee beans into grounds. Conical burr grinders produce consistent grind coarseness without scorching.

Hand grinders are powered by manually turning a crank to grind the beans and usually have a burr grinding mechanism. Hand grinders have one major advantage over electric grinders- they are very quiet. If you make coffee early in the morning while others in your house are asleep, a hand grinder is quiet enough not to wake anyone up.
Some electric grinders are automatic- you press the button once and the grinder runs for a set amount of time. Other electric grinders run only while the button is held down. I prefer the automatic variety so I can walk away while the grinder runs.
Troubleshooting Coffee GrindersSometimes a coffee grinder will get jammed. Here are some steps to troubleshot a coffee grinder:
- Unplug the coffee grinder
- Pour the beans from the hopper into a bowl
- Clear any beans or bean fragments from around the grinding blade or burr
- Manually turn the blade or burr to make sure it is free of obstructions
How to grind your own beans at the grocery storeMost coffee shops and grocery stores offer coffee grinders for you to use for free. These grinders are quick and easy to use. Here are the steps to grind your own coffee beans at the store:
- Fill the hopper with selected coffee beans
- Set the desired coarseness for the ground coffee using the knob (select medium for most coffee makers)
- Place a bag under the chute,
- Press and hold the grind button.
- In about 30 seconds you’ll have about 12 ounces of ground coffee ready to take home
Note: Don’t over-fill the bag or it will be difficult to close

The main issue with grinding the beans at the store is that coffee beans start to lose flavor almost immediately after grinding. You will get much better tasting coffee with more rich and complex flavor if you grind the coffee beans immediately before brewing. The only practical way to do this is to have your own coffee grinder at home.
Grind Adjustment- Selecting coarse to fine grindAutomatic drip coffee makers produce the best coffee using medium coarseness. If you use grounds that are too fine, the grounds will get packed together in the coffee filter and will not allow enough water to pass through efficiently. Espresso makers use a finer grind since the high temperature and pressure in the small brewing chamber produces the maximum flavor with fine grounds.
