Have you tasted pre-ground coffee? Compare it with a cup of coffee made from freshly ground beans, and you will see a world of difference. There is a reason why most coffee addicts treasure their coffee grinders as the most important appliance in the kitchen. Freshly ground coffee gives you the best caffeine kick that will last long, and will give a boost to the flavour of the drink so that your coffee breaks become the most enjoyable part of your day!
Why do you need to freshly grind coffee beans?
If you confess to a true coffee lover that you buy pre-ground coffee powder, you will earn a ridiculous look of disbelief. There are several reasons why you must buy coffee beans and grind them fresh every day for your cuppa.
Risk of contamination
Ground coffee is very delicate. If you leave the powdered coffee out for long, it will immediately lose its taste. Also, it is very easy to contaminate the flavour if you do not keep it properly sealed. Even if you are taking good care to make sure your pre-ground coffee is in an air tight jar, you will risk exposing it to air every time you open it. With time, the volatile oils of the coffee powder will dissipate, and you will be left with bad tasting coffee.
Most of the delicate aromas and oils present in coffee powder react with the oxygen in the air and dissipate. As a result, your coffee powder will lose its flavour and smell through any exposure to air. Since beans have much less exposed surface area this effect is much slower if you store your coffee as whole beans.
Depletion of carbon dioxide
When coffee beans are roasted, carbon dioxide is trapped inside the porous coffee beans. This gas is extremely important as it will ensure that the oils of the coffee beans mix thoroughly with water. When you grind up the beans, however, carbon dioxide is released. If you leave coffee powder out for long, the gas will deplete completely and the oils of the coffee will not blend in water.
Since coffee powder dissolves in water, exposing them to air for long will cause the oils to dissolve (due to the humidity in the air). Again, the coffee powder will lose its taste and taste bitter or bland when brewed.
What should you use to grind coffee?
If you are ready to grind your own coffee beans, you need to do some adequate research on what type of grinder you should buy. While – traditionally – blade grinders were most popular, over the years many households have replaced their blade model with burr grinders. A burr grinder contains two abrasive surfaces which revolve in opposite directions. The coffee beans are crushed in between them, and the small pieces are reduced to powder. There are a few advantages of using burr grinders:
- Burr grinders break the coffee beans down to uniform pieces, but the blade models do not. This is important as different-sized coffee particles will dissolve at different rates into the coffee when brewing.
- Burr grinders let you have more control on grinding your coffee than the blade grinders, with adjustable settings from coarse to fine grinds.
- Burr grinders do not heat up the coffee as there is only a small amount of friction generated during the grinding process, unlike the fast moving blades of a blade grinder.
Tips to grind coffee well
Remember that there are different sizes of ground coffee beans that you need to use for different brewing methods. For example, if you want to use French Press or Vaccum Coffee Maker, you need to get a coarse grind. In that case, you need to set your burr grinder up to make sure that the coffee beans get broken into larger particles. For espresso, you need a fine grind and for drip or pour-over you need a medium one.
You also need to let your coffee beans and taste decide what exact level of grind you desire. To get the best out of your coffee, use a trial and error method to test your way to the right settings. Try grinding a few of your coffee beans using your burr grinder and see what settings works the best in order get the best brew.

Frequently Asked Questions
Q: How to clean your coffee grinder?
There are lots of ways to clean out a coffee grinder. However, you want the method that properly deals with the oil buildup. If you don’t address the residue, it can get quite funky and rancid. One quick trick you can use to blot up all those oils and fragments is uncooked rice.
Put ¼ cup of rice in your grinder and grind it for a few minutes until it’s pulverized. The oils will get absorbed by the rice flour. Dump out the flour and rinse your grinder with a damp cloth.
Q: How often should I clean my coffee grinder?
As mentioned above, coffee grinders tend to accumulate a lot of oils and bean residue overtime. As such, they need to be cleaned on the regular. Failing to do so could lead to a rancid and very disgusting grinder.
If you’re using the cleaning method above, it’s quite easy and fast to perform. The rice method works just fine no matter what type of grinder you have. Experts recommend cleaning out your grinder at least once every week.
Q: How do you remove static electricity from coffee grinders?
One of the most common frustrations when using coffee grinders is the flecks of coffee sticking everywhere. That’s because of the static electricity generated when the coffee beans are ground against the metal burrs.
Needless to say, the static can make your grinder look incredibly messy. Fortunately, there’s a simple hack to help you clear all the static every time. Just add the coffee beans to the grinder as usual. But before grinding, add about 3 to 4 drops of water in the hopper. Be very careful not to overdo it. Once you grind your coffee, you’ll be surprised that there are no flecks stuck all around the inside.
Q: How do you sharpen coffee grinder blades?
After prolonged use, you might notice that your coffee grinder takes a bit longer to achieve the same results it did when it was brand new. But instead of replacing your grinder, you could just sharpen the blades.
Now, remember that even when dull, the blades of a grinder are still sharp enough to injure you. So handle them very carefully. Start by pouring an entire cup of uncooked rice in the grinder. Run the grinder for a couple of minutes until the rice is well ground. Next, unplug the grinder, dump out the rice flour and wipe it dry with a clean cloth. You’ll notice a significant improvement in the blade sharpness.
These machines all provide a valuable addition to any coffee enthusiast’s kitchen. The choice between them comes down to whether one is looking for a budget grinder or a more advanced, but much pricier, option. Regardless of which machine you choose, though, having freshly ground coffee from a burr grinder will make your enjoyment of daily cup much greater.
