What skills do you have in making coffee? how to make delicious coffee?

The importance of water is beyond doubt! If you use bad water to brew coffee, even the best beans will be in vain-because bad water can destroy the best coffee. Even a simple "filter kettle" can filter out many bad substances for "tap water", making the brewed coffee more fragrant, strong and mellow. Like making tea, you need to avoid using distilled water, and if the tap water in your place is of poor quality, using clean mountain spring water is also an ideal way. Fourth, enough coffee beans must be used. Too little coffee powder may lead to bitterness or insipidity, but not too much at a time. The standard amount of coffee is: use "two flat spoons" (about 15g) coffee beans (powder) to brew "one cup" (about 180cc) coffee. Please adjust your coffee use according to this proportion. In general, the most suitable water temperature for brewing coffee is between 88 and 94 degrees Celsius. Avoid using boiling hot water to brew coffee. Let the water boil and let it sit for 1-2 minutes before making coffee. 6. Keep the coffee equipment clean at all times. Do not bring the concept of "raising a pot" to the coffee utensils. Every time you use a coffee utensil, you need to clean it immediately and keep it clean and dry in a ventilated place. if you apply the concept of "raising a pot" to the coffee utensil, you will get a cup of bad coffee full of strange oil smell. Drink the coffee within ten minutes. Don't believe that your coffee can be kept warm for more than half a day on the "electric heat preservation tray" of the coffee pot. The longer the coffee is laid aside, the flavor will gradually fade away and the taste will go away quietly. After the coffee is made and finished in ten minutes, he is the expert who knows the way.
