My tastes have not changed in 4 years. My ability to verbalize what I am liking about each blend is severely lacking. I like cooking spices and flavors. Subtle blends but no goopy messes.Another strategy may be to post the blends that you like here and ask others to provide suggestions for similar blends.
If you know exactly what it is that you like about the blends that you like, you can look for others like them.
The problem will be that your tastes may change.
