Water: the water you use is very important. If you are using tap water, let the faucet run for a few minutes before filling the coffee pot. Remember to use cold water, not distilled or softened water.

Ratio of water to coffee: a common law is that six ounces of boiling water is better than 1 to 2 tablespoons (tablespoons) of ground coffee powder. You can adjust it according to your personal preference.

Water temperature: for the best extraction results, the temperature of your coffee pot should be kept at 195 to 205 degrees Fahrenheit. If the temperature is too low and the extraction is not enough, the coffee will be insipid and tasteless, and the high temperature will make the taste worse. If you make coffee by hand, let the water boil, but don't boil it too much. Turn off the heat and let the water cool for a minute before making coffee.

Enjoy the brewed coffee immediately-pour the coffee into a large warm cup or coffee cup to keep the temperature as long as possible. Brewed coffee will immediately begin to lose its best taste, so only the portion to be used is used. Coffee should never be left on the electric stove for more than 15 minutes, or it will taste burnt. If the coffee is not brewed for immediate use, it should be poured into a warm, isolated thermos and finished within 45 minutes.

Never reheat your coffee-a cup of carefully prepared coffee should be tasted as carefully as it was prepared. Take some time to smell it. Take a sip and pay attention to the taste of the coffee. How does your coffee compare with other coffees in terms of itself, acidity and balance? Every bite should be tasted and enjoyed.

But in today's coffee market, such as coffee shops in Australia, it is common. They say that if the coffee is overextracted, wouldn't it take longer for the autoclave and siphon kettle to extract than that? So what's wrong with doing this?

Let's not compare the differences in taste between the two methods, because differences arise when it comes to this aspect. But it should be known that the caffeine content in light coffee extracted for a long time will be higher than that made by diluting a standard cup of Espresso with water. Even so, there are two ways to make coffee: diluting Espresso with water and adding water before Espresso. Is it right to make a cup of light coffee with Italian machine effluent for a long time? There are two opinions. Traditional Espresso advocates don't think so, because coffee is overextracted, especially in the later stage of extraction, which removes the miscellaneous flavor and excessive caffeine of coffee powder, and these people despise this method.
