Coffee Grinders

blade coffee grinder - redFresh-ground coffee - that phrase just sounds good, don’t you think? Once you’ve picked out the type of coffee and roast you want, the next step toward getting the perfect cup is to grind the whole beans. Naturally, the gadget you use to do that is a coffee grinder.

For decades, almost no one ground their coffee at home. Coffee came pre-ground in vacuum sealed tins. Some supermarkets did (and still do) have grinders in the coffee isle. You select whole beans and grind them before you head to check out.

However, grinding coffee a long time before you brew it causes some loss of flavor. The longer the delay before brewing the more significant the loss is. The reason it that grinding greatly increases the surface area of the coffee. This makes it easier for volatile oils to escape and oxidation to take place.

You can compare what air exposure does to brewing coffee. If you pour hot water over whole beans you won’t get much a cup of coffee.  Almost all of the flavors remain trapped in the beans. However when you grind the beans the much greater surface area allow the hot water to extract the richness of the coffee bean.

This is great when you want to make a cup of coffee. It’s not so great if you are storing ground coffee and losing flavor to the air.  Keeping coffee in a closed container helps, but only to a limited extent. The longer coffee is kept the more flavor it loses.

I remember when I used to buy pre-ground coffee in a can.  A can would usually last me about two weeks or even longer. The coffee was reasonably good when I first cracked open the vacuum sealed container. That wasn’t the case by the time I got to the bottom of the can.

Back then, opening a fresh can of coffee was a treat I looked forward to. I knew I’d be drinking better coffee for a few days.

That changed when home coffee grinders became widely available. Now it is easy to have freshly ground coffee every time you make a pot.  The biggest issue now is just what coffee grinder to get. This page is here to help you figure that out.

Types of Coffee Grinders

Coffee grinders fall into one of two main categories: blade coffee grinders and burr coffee grinders. Both types of grinders get the job done, but there are advantages and disadvantages to each and one type will perform better in some applications than the other.
