The quality of Italian coffee the taste of coffee comes from baristas.

Once you've experienced a cup of good quality espresso, you can't take another cup of bad espresso! Just as coffee beans are essential to the quality of espresso coffee, so is the knowledge and skill of the barista. It doesn't take high tech to make espresso,

But there are a lot of necessary knowledge and skills in the production process, and there are also some taboos that need to be mastered by baristas.

The first and most important thing is to use high-quality coffee to make, coffee must be fresh. Usually, the roasting degree of Italian coffee is relatively deep, and the blending should also follow the blending principle of Italian coffee. Arabica coffee beans should be the main ingredient in the blending.

Coffee is best consumed within 2-10 days of roasting, after which the quality of coffee declines rapidly. Because of this, you should try to buy coffee less at a time and more frequently, such as once a week, to minimize hoarding. The space in which you keep your coffee should be cool, dark and dry and ventilated. Avoid refrigeration unless you have to deliberately prolong the drinking time of the batch, or the space in which you normally keep your coffee is too hot (above 80 degrees Fahrenheit) and you have to lower the storage temperature.

Next, you need a well-maintained commercial grade espresso maker. Traditional espresso machines have the ability to make a cup of high-quality espresso coffee, and from this point of view, traditional semi-automatic coffee machines are more capable than fully automatic coffee machines. A fully automated coffee maker that grinds, fills, presses, extracts, and even froths milk at the push of a button is nowhere near as skilled as a barista. It is possible to produce coffee of consistent quality, but the quality of the coffee itself is in the middle to lower levels. If you're looking for quality espresso, this isn't the place to stop.

If you are using a traditional semi-automatic espresso machine, then a high-quality coffee machine grinder is also essential. To see the quality of a coffee grinder, the key is to see the stability of its grinding and the adjustability of its grinding thickness. Sometimes you need to adjust to a very small range to finally get a cup of perfect espresso. So if you haven't purchased a grinder yet, determine the adjustable degree and range of grinding thickness of the grinder you will purchase before purchasing.
