Did you know that ground coffee, when it is exposed to light and air, tends to degrade quickly? In a matter of days, your pre-ground coffee can loose a lot of its flavor. That’s why people who are serious about the taste of their coffee prefer to grind their own coffee beans right before brewing. If you’ve never ground coffee beans before, it can be hard to know where to start. Here are some basics that you should know.
The first thing that you need to know about is the size of the grind. The ground beans can be very coarse, or can be ground to a powder of about the same consistency as talcum powder. One reason why the size of the grounds matters is that if they are too small, they may pass right through a filter, and get into your coffee. Or, they may clog up the filter, causing your machine to overflow. Another reason why you need to make sure your coffee grounds are the right size is that the flavor will be extracted differently. With very coarse grounds, the flavor is extracted slowly, so this is better to use with a brewing method where the water is present for a long time. Very fine grounds will be extracted quickly, meaning that the water should only be in contact with the coffee grounds for a short time.
The method that you are using to brew your coffee determines what size grounds you need. Coarse grounds are best for French press, since the water will be in contact with the beans for a long time. Medium size grounds are good for typical drip coffee makers, from the simplest counter-top model to a commercial grade stainless steel under counter coffee maker. A much finer ground must be used for espresso. The finest grounds are used for Turkish coffee, and usually require a special Turkish coffee grinder to produce.
Last, the type of grinder that you use is crucial. The most common types are two-bladed spinning grinders. While these are the most affordable, and can be a good introductory machine, they aren’t ideal. They don’t actually grind the beans, but instead chop them. It is also difficult to get grounds of uniform sizes. A better choice is a burr grinder. In this style, two metal plates, either conical or cylindrical, grind the beans between them, producing a uniform size of particles, and giving you much better control over the final size. Some people even prefer a manual coffee grinder, for the control it gives you, and for the relaxing and antique feel of them.
Grinding your own coffee beans isn’t difficult, and it can make a huge difference to the taste of your coffee. Why not have freshly ground coffee in your own kitchen?
