Buy coffee grinders cheaply: Consumer tips
However, it is particularly the grinding process that determines the aroma of the coffee, as the fineness of the grind affects the emergence of bitter substances in the coffee. Coffee lovers prefer freshly ground coffee just before preparation, as there is a rapid loss of aroma in ground coffee after opening vacuum packs.
Are there different coffee grinders?
Yes. For this reason, one should primarily consider what purposes it is to be purchased for. Private households certainly have different requirements for the grinder compared to, for example, catering businesses. Coffee grinders can be roughly divided into three groups: grinders with portioners are especially recommended when coffee consumption is very high. This is rather rare in a private household, so these coffee grinders are mainly used in the catering industry. More suitable for home use are grinders with containers. Here, several portions can be ground in advance, which remain safely in the container. However, portioning is difficult here. The portioning problem can be managed with coffee grinders with portafilters. Here, portioning is precisely possible without any leftover amounts. But even here, just like with the grinder with a container, the coffee powder can become electrostatically charged. However, this type comparatively well solves the problem of being able to prepare small amounts fresh. The ground coffee is therefore either caught in a storage container, collected in a doser, or ground directly into the portafilter.
Furthermore, coffee grinders can also be classified according to their various grinding techniques. Here, a distinction is made between blade grinders, disc or flat grinders, cone grinders, and roller grinders. Especially the disc and cone grinders guarantee the best results here. Both grinding mechanisms not only cut the coffee beans but also break them. This ensures that the beans are ground evenly, creating a uniform and as large a surface as possible, which guarantees optimal release of the aromatic substances.
What should you consider when buying a coffee grinder?
Since the task of the coffee grinder is to grind coffee, you should primarily pay attention to how the coffee is ground. Additionally, it is advisable to keep an eye on the grind strength. Is, for example, a stepless adjustment possible, through which one can easily find out which grind level is personally preferred? What amounts of coffee should be ground in a specific period? And finally: Is the coffee grinder you prefer easy to clean or not?
