I don’t like hard liqours, doing anything wrong?

Alright so I bought a really nice .25l of grape whiskey (kind of deal, not actually sure about what it is), pretty known brand in my country, got some ice ready, chilled the drink itself, chilled the glass, put ice in glass, poured the drink, took a sip and it tasted like shit, mouth feel bad swallowing even worse, to be expected with first sip, after a few sips over next half an hour i kind of got into groove with mouth feel but swallowing just made me make face that homer simpson made in that shinning episode everytime, it was insane, I love beer though and good champagne and wine is alright, is there a way to enjoy hard liqours better or is it just jover?

Note: I don’t even actually care about whether I like or not like hard liqours in the end, I can go without vodka fuck it, it doesn’t bother me, its just that if there is a way to enjoy something without getting harmed you know why not?
