At my first job, the boss/owner of the company knew a lot about wine. As a result, the Christmas gift basket contained a lot of excellent wines that I wouldn't have been able to pick out myself. But I guess that's an example of expertise.
And of course it's not much use to someone who doesn't like wine (they may have had a non-alcoholic alternative).
"excellent wines" or a great example of a wasteful gift because excellent wines aren't substantially better than OK wines, unless you are a wine enthusiast (not just a wine drinker).
It's like giving out RTX 3080s en masse. Most people won't get the value of what you spent.
And excellent wine can be a lot better than an OK wine for a similar cost. I think it's a perfect example where some expertise can dramatically increase the value. For wine drinkers, at least.
The great thing about wine as a gift is that it doesn't go bad quickly. Even if you don't drink it, you can re-gift it to someone who will appreciate it.
