Even a non-professional can decide whether to buy a particular package of coffee.
One of the signs that is worth paying attention to is not the price, contrary to popular belief, but the expiration date or roasting date.
If this information is not on the packaging, it is better to refuse the purchase - just as in the case when the expiration date is approaching or there is no degassing valve.
The second point that those who prefer the mixture should definitely clarify is the composition of the drink.
The classic version for making espresso contains 80% Arabica, which provides the taste and aroma, and 20% Robusta, which is responsible for the strength and reduction of acidity.
Be sure to evaluate the appearance of the grains.
As a rule, beans with primary defects do not reach roasting, but mistakes can be made in this process.
You should not use beans that have a charred outer part, a grain embryo, or those specimens that have small round depressions that resemble craters.
