To get the best taste of coffee, the easiest way is to buy freshly roasted coffee beans and grind them each time you need to brew coffee. If you buy coffee beans and grind them in the store, you should let the clerk know what coffee machine you use at home, piston coffee maker, drip coffee maker or espresso machine... Because different coffee machines need to use coffee powder grinding degree is not the same! There are many kinds of bean grinders on the market, which are basically divided into two categories: one type uses blades, which is cheaper; the other type uses grindstones, which are relatively expensive, but can grind more evenly. When using a non-blade grinder, you need to switch it several times, and pay attention to shaking evenly, otherwise the coffee will emit a scorched smell, and it can also produce other strange smells. Coffee beans the most basic three grinding methods: "coarse grinding","grinding","fine grinding". Coffee brewing in a variety of ways, there are siphon type, drip filter type, distillation type, filter bag type, steam pressure type, cold water type... but the most interesting way is the most Oriental siphon type, it originated from the United Kingdom and has the charm of Oriental tea culture, which has a consensus on water quality, water temperature and time requirements. To avoid bitterness, do not boil coffee. The ideal temperature should be between 90 ° C and 96 ° C (i.e. 195 ° F to 205 ° F). Do not heat coffee again. It is recommended to determine how much to make each time according to the amount of drinking to ensure that the freshest coffee is drunk. The temperature at which coffee tastes best is 86 degrees Celsius (185 degrees Fahrenheit). 3, use fresh, cold water to make. Each cup of coffee contains 98% water. If the water has a strange smell, consider using filtered or bottled water. Used coffee powder should not be used again. These are coffee residues, which contain only bitter ingredients. 5, according to the coffee machine to choose the corresponding grinding degree of coffee powder. Coffee ground too fine can cause over-extraction, bitter taste, or clog coffee makers. Grind too coarsely and it will cause the coffee to be as light as water. If a drip coffee maker is used, proper grinding should ensure that the coffee drips within two to four minutes. 6. We recommend that you mix 180 ml (6 oz) of water for every 10 g (2 tablespoons) of ground coffee. No matter how much coffee you make, stick to this ratio. Of course, you can adjust this ratio appropriately according to your own taste. But remember that grinding too fine or using too little coffee will only make the coffee taste thin and bitter. 7. Keep coffee warm on the stove for up to 20 minutes. Over time, the flavor changes. The use of vacuum thermos bottles can keep the flavor of coffee for a long time.
