Great analogy OP.
Baylinor, I drink way more wine than beer, but beer has become as complex and interesting as wine and audio.
As others have stated, a somm must be able to identify a wine in detail, blind, to get certified, and there are different levels. I have a friend that is a top level somm and he did it just for fun.
For us laypersons, the rules are simple.
1. If you like the wine, it is good. No matter what anyone else says.
2. If you like the sound of your component/rig, see rule #1.
No certification required.
The best resource is an honest, brick and mortar audio dealer but from what I hear from y'all is these are getting harder to find.
