i highly recommend cupping coffee, or at least trying 2-4 different coffees at the same time. you have to compare them side by side, that's where the notes make themselves apparent. trying only one at a time will not be sufficient as the differences can be subtle when recalled only from memory.

believe me, i don't have a super palette and have a hard time finding the right notes myself. you can try tasting while looking at the SCA coffee wheel[1], using the inner ring for broad categories.
