Are you looking for the right beans for your fully automatic coffee machine? We explain to you what you should pay attention to when buying coffee beans.
Choosing the right coffee beans: you have to pay attention to this
In principle, you can use any bean for your fully automatic coffee machine, provided it is suitable for fully automatic coffee machines. However, this does not always make sense, since, for example, different beans are usually used for a black coffee than for an espresso. But one after anonther.
In order to find the right coffee for your fully automatic coffee machine, three points are particularly important:
quality of the coffee beans
Roasting of the coffee beans
Settings of the coffee machine
Ultimately, however, it also depends on your own taste, which you will probably only find out over time. Let’s take a closer look at each point.
Two types of coffee dominate world trade
There are around 40 different types of coffee worldwide, but only two dominate the market. The Arabica bean makes up around 70 percent of world trade, the Robusta bean just over 30 percent. The two beans differ in appearance and taste. The Arabica bean is longer, flatter and oval in shape. The caffeine content is lower compared to the Robusta bean, but it is said to have a finer, slightly sweet taste. The Robusta bean is slightly smaller and has fewer fats and lipids. Therefore, their crema is a bit firmer and is therefore often used for espresso.
Coffee bean or espresso bean?
Fully automatic coffee machines work fundamentally differently than filter machines. Instead of slowly filtering the coffee, the fully automatic coffee machine works with a pressure process. This pressure is what creates an espresso.
The espresso beans that you can buy in stores are usually a blend of different types of beans that contain a higher proportion of robusta. These ensure a strong, intense taste. With a mixture of Arabica and Robusta, you can benefit from the positive properties of both beans. This makes espresso beans ideal for use in your fully automatic coffee machine.
Don’t let the term “espresso bean” fool you. The term is somewhat misleading, because the so-called espresso bean is basically a coffee bean. However, beans used for espresso are roasted darker, have more caffeine and are stronger in taste. So it can be an orientation.
This can also be the case for medium roasted coffee beans. The use for coffee crema is often noted on the packaging.
Which beans are unsuitable?
Avoid caramelized beans for the fully automatic machine. The sugar can clog the grinder in the machine and in most coffee machines this is very difficult to reach and clean. Flavored beans such as amaretto or Irish cream are also not recommended for this reason.
Caution is also required with very oily coffee beans. If the bean is very shiny, essential oils are already escaping. This is a clear sign that they shouldn’t be using these beans. The lipids come out when the coffee has been roasted past the second crack. This is often the case with dark Italian roasts.
But that doesn’t mean that you have to do without the variety altogether. Essential oils can also leak out if you have stored the coffee beans for a long time. After buying, you should use the beans relatively quickly and only store them in airtight packaging.
Roasting: Which degree of roasting for use in the fully automatic machine?
In addition to good bean quality and the bean mix, the roasting of the coffee beans is of crucial importance. In principle, a distinction is made between light, medium and dark roasting. Some roasting masters even subdivide into five degrees of roasting and indicate their roasting as medium-light or medium-dark. The different colors are caused by different roasting times. A coffee bean has over 900 different aromas that are released at different roasting temperatures. Filter coffee beans are usually roasted lighter, while espresso beans tend to be roasted darker.
Note the drum roasting process, if specified. Because drum roasting is much gentler on the bean than industrial hot air roasting, where many flavors are lost.
