How much coffee powder is put in espresso at a time-the thickness of espresso powder

The necessary condition for how to cook coffee powder: use "good water" to cook coffee powder. In a cup of coffee, more than 98% of the ingredients are "water". The importance of water is beyond doubt! If you use bad water to make coffee, even if you use the best coffee powder, it 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. If the tap water in your place is of poor quality, using clean mountain spring water is also an ideal way to cook coffee powder without a coffee pot. First of all, you can add 250 milliliters of water to the pot and heat it to a boil (preferably a small bite or a thinner one such as a cup). Then, pour the 50cc water into the coffee cup and warm the cup (if you don't have a special measuring cup at home), pour two tablespoons of coffee powder into the pot (usually a spoonful of coffee powder weighs 13 grams in a coffee shop, and two tablespoons of coffee powder weighs only 25 or 6 grams). Pour and stir, usually two or three times clockwise. If you stir too much coffee, it will turn sour and cook for about 60 seconds. Second, pour out the hot water in the coffee cup, put the filter cloth on top of the cup, and press the center of the filter cloth on the cup slightly so that the coffee liquid will not spill when you pour it.

In the Italian coffee machine, the temperature value is mainly affected by the size of the boiler or heating block, as well as good heat conduction materials, there is an obvious difference between the toy machine and the professional Italian coffee machine. In general, many standard toy machines are equipped with small boilers (below 200ml) or small heating blocks, so it is difficult to achieve a stable temperature, and the temperature fluctuates greatly in the process of coffee extraction. The machines of many small household appliance brands are like this (such as Cankun, Delong, Electrolux, etc.). After all, these brands are not professional coffee makers. Another thing to consider is a good heat conduction material, a good machine has a better circuit and pipeline design, using copper or stainless steel as the main material of the coffee machine, they have good thermal conductivity (to ensure uniform and stable temperature). Otherwise, it is still more than 90 degrees from the boiler to 70 or 80 degrees from the coffee machine, which will be more obvious in the low temperature environment.
