Very observant my dear friend... It is a sign that you really love coffee..... It is difficult to have a defined description in the local brands, I for example buy Creole coffee and it does not have any kind of description, only the one that the producer verbally indicates to me.
Yes, it's always like that. One must trust one's instincts and decide whether you're buying it or not. I used to smell the beans; now I also examine their color, feel their weight. The sellers don't like this, but I won't pay for coffee old and tasteless, or stale. So I take my time while the vendor suffers and calls me names in his mind, haha. I'm not afraid of their giving me that wary look, haha.
