Well said Pussyhands! It's not the activity that defines the person, but the person who defines the activity!
in line with your examples, drinking wine:
For the connoisseur who appreciates fine wine, drinks it in moderation, savours and enjoys every glass - it's a virtuous pursuit.
For the alcoholic, who buys the cheapest cask wine they can find and gulps it down to get drunk and forget about their problems - it's a vice.
They're both drinking wine...
