If you don’t like straight liquor, keep it for re-gifting to someone who does. Cheap vodka for White Russians. Who can tell the difference?
We happened on Flaviar - a purveyor of spendy alcohol - & have tried a few. I found a gin (Reisetbauer Blue Gin) that makes Sapphire Bombay seem poor in comparison. And I loved the SB when I tried it, compared to cheaper brands.
Of course, you could just keep it, buy others to compare with & educate your palette. ;-)
There IS a difference for "taste" in vodkas.
The very best are as smooth as silk.
Just like a single malt scotch.
Gotta try really good ones.
Compare and contrast with crappy brands.
Then you'll understand.
