Why ruin a good quality wine ?
Not if it's good quality wine, and in any case you only have a few glasses.
It's never good to mix alcholic drinks such as beer and whiskey or whiskey and wine or wine and beer.
Any professional drinker knows that causes serious hang overs.
Campari is an Italian alcoholic liqueur obtained from the infusion of herbs and fruit in alcohol and water.
To mix that with a quality sparkling wine sounds like a vomit inducing headache to me.
Sounds like something Ha Ha Hairy would drink for a Christmas drink.
