By definition, coffee of origin, or the recognition of a coffee as its origin, should essentially be an extra point of quality. By origin, you have to understand the fact that we know the origin of that coffee, or traceability, as you say in expert terms. The moment we actually get our hands on a pack of coffee, you need to find information about the origin or geographic region of that coffee. It is not mandatory or legally required information, but it is information that should be found on the websites or label where you order your coffee, along with the description of that coffee, to help you better understand where that coffee comes from. It is also considered as information indicating its quality.
When you go to the store or go to a website and buy a pack of coffee, if the label says only "Arabica coffee", it means quality coffee beans.
The more information you have about a coffee, the better quality it will be.
In most cases, traders offer the origin coffee exactly as the country it came from. Peru, Colombia, Brazil, Ethiopia, which is not wrong. It is basically the minimum amount that can be put on a label. It can be said that the origin of coffee. Instead of looking at the label and seeing that it's an espresso coffee, you can also find out what that coffee is made from. It could just be a mix between arabica-robusta. Many do not tell or hide this information. Because some coffees are of better quality, while others are of lower quality.
The more information you have about coffee, the more useful that information is for you, and it is a proof of quality: You can get the necessary detailed information from search engines, with the country of origin, the geographical region, maybe even farm or cooperative information.
