Underage Citation loopholes?

I am 18years old, i was at a party and the cops broke it up. They took down my name and other info but it was all basic info, i didnt have my ID or social security nor did they fingerprint so there really isnt any concrete evidence it was actually me. They did not breathalize or blood test me they didnt even ask if i was drinking i was clearly drunk tho so they put down self admit. what would happen if i show up at court and plead NOT guilty saying I was not there, i was actually sleeping in that night with my roomate? Because its not what you know its what you can prove and there is no proof that the info written on the citation was actually given bny me and not a friend who slandered my name.
