The knowledge of making coffee is quite esoteric, from water temperature, grinding particle size, extraction tools, and even filtration equipment to a set of principles. "filter" can be said to be the last step of a cup of coffee, but also greatly mastered the key to flavor, while trying a variety of extraction methods, do not forget to understand the differences of various material filters.

And the quality of coffee filter paper is also the key to affect the flavor.

Filters span various fields, and many kinds can be found on the market. Choose different filters according to the function of the machine, the positioning of the coffee shop and the taste you pursue. Like a popular filter, it is only popular for a while; there are also filters with professional functions that can be used for a long time and even represent the image of a coffee shop. As the filtering method will directly and indirectly affect the mellow feeling and flavor of coffee, the role of coffee will be different according to the filter used, so it is regarded as an important factor. Although there are many kinds of filter materials on the market, they can be roughly divided into three categories. Other relevant variables in the extraction and the advantages and disadvantages of each filter and other details are skipped here, mainly with the general content.

① metal filter, filter cup (perforated metal plate)

There are various specifications for the size and number of holes in the metal plate, so the degree of grinding must be considered before use. This tool basically has nothing to do with filtering drinks, only very fine particles can pass through.

② filter cloth (cloth)

It is a filter that helps to extract excellent flavor, taking flannel and velvet as an example. Before using the filter cloth, it must be boiled in hot water and well managed before it can be used for a long time. Oil infiltration into the filter cloth is easy to produce spoiled flavor, and the flavor of the beverage will be changed when it is cooked. Therefore, we should pay attention to the storage temperature (after use, put it in a container filled with cold water or put it in the freezer), and choose the container carefully.

③ filter Paper (paper)

Although it is considered to be the best filter to extract the refreshing taste, it is somewhat difficult to establish an ideal coffee extraction environment with filter paper. in addition, if the filter paper is blocked, it is likely to change the flow of water and lead to over-extraction. However, in addition to extracting the refreshing taste, it is still loved by many coffee shops because of its convenient use and convenient preservation and management.

Basically, the quality of coffee depends on the ability of the brewer. Although "people" is the biggest variable. " This sentence seems to be true, but it is the most important process to choose what kind of coffee beans and appropriate utensils to mix out the flavor you are looking for. Of course, instead of choosing the world-class coffee beans to brew, we should first imagine the process from coffee beans to brewing into a cup of coffee, recall all the processes and six factors in the extraction process, and then adjust to brew the coffee. This is the way to get closer to the ideal coffee.
