Do I need to install a water purifier and a water softener in the cafe?

Coffee shops must install water purifiers and water softeners. To brew a good cup of coffee, the level of effort is not only the choice of coffee beans and the roasting and brewing. 99% of the coffee poured into a coffee cup is "water". From this point of view, the key to the deliciousness of coffee is the nature of the water. In recent years, there are various bottled waters on the market. I often hear words such as "hard water" and "soft water". In fact, the identification is based on the hardness of water, and water is roughly divided into hard water and soft water. The so-called water hardness refers to the total concentration of calcium and magnesium ions in the water. When the concentration is low, the water is soft, and vice versa is called hard water. For example, almost all tap water or groundwater in Japan is soft water, while most of it is hard water in Europe and the United States. As for which hard water or soft water is more suitable for brewing coffee, the answer is of course soft water is more suitable for brewing coffee. The mineral content in the water will also affect the taste of the water. Generally speaking, water with too much or too little mineral content is considered to lack balanced water quality. Assuming that the content of calcium and magnesium ions is too high, it will hinder the extraction of the main components of coffee such as caffeine, high-quality tannins. At this time, the water purifier can play its purifying effect. On the other hand, such as water with higher hardness, its impact will also be directly reflected on the bitter taste of coffee. In order not to affect the taste of the coffee itself, it is also recommended to install a water softener to soften the water quality.
