Many well-meaning coffee lovers kill the goodness locked within the coffee beans with the wrong type of grinder, one that should never have been designated for coffee.

In another post, I addressed how important the water is that you use to brew your coffee. Now we need to address the second most frequent way people murder their coffee beans: By using a blade grinder that’s really meant for pulverizing spices.

Only Grind Coffee with a Burr Grinder

Why not grind coffee with a blade, you ask? Because blade grinders result in uneven grinds. This is terrible for coffee, which must be evenly ground in order to have a balanced extraction (the process by which the water passes through the ground coffee and produces and “brews” the resulting cup of coffee).

Do yourself a favor, and relegate that blade grinder to your spice cabinet.

Coffee beans last much longer in their whole bean form (when kept away from oxygen). Once the coffee has been ground, we recommend brewing and consuming the coffee within one to two weeks. As whole beans, roasted coffee can remain fresh for 3 months, and sometimes even longer.

Which burr grinder do we recommend? We sell Baratza grinders in our store (you can get one online here) and their affordable Encore model is the best seller. But it depends on how you brew (you should invest in a more sensitive, higher quality grinder for an espresso machine, for example), your budget, your aesthetic, and so on.

If you would prefer to mix it up—using some coffee for French press, and some for pour over, then I recommend getting a burr grinder. Then you control when and how often you grind your beans and the way you will use them, depending on the brew method.

Bonus Tip: Don’t Refrigerate Your Coffee Beans!

Never store whole bean or ground coffee in the fridge. The refrigerator can cause condensation inside the bag or container of coffee, which will begin a brewing and degradation process. Coffee beans or ground coffee will be kept freshest when stored at room temperature either closed within the foil-lined bag it comes in, or inside a vacuum container made for coffee.
