Last week we discussed the important factors in making sure that the quality of our coffee remains high once it leaves our warehouse. The subject of coffee grinding was briefly brought up and how it is important to grind coffee as needed. This blog post will dig deeper into the subject of grinding coffee and will focus on why a specific grind size is important depending on the way the coffee is being brewed.
There are many different ways to brew coffee and each method has a specific grind size needed in order to maximize flavor and taste. If beans are ground fine, more surface area will be exposed to water. The more surface area of the grounds that are exposed to water, the more potential for flavor to be extracted from the coffee. This means that brewing methods that require longer periods of time, such as a French Press, need a courser grind so that the coffee is not over extracted. Over extraction can lead to a bitter taste. Under extraction can lead to a weak or sour taste. Below is a chart that links specific brewing methods to the appropriate grind size and gives an example of what the grind size should look like.
