Should I drink beer/champagne at my friends quince, next year when im 14/15?

Im a super good kid. Never drank or smoke. But some of my friends do. Not the girl who invited me to the quince, shes good too. Their planing an open bar and my friends uncle can get us drink while were there. I mean she drank before, but with her family. I just want to try it once. I dont think ill get addicted or anything, i mean ill have 1 1/2 drinks at the most. I dont plan on go drinking with frieds after or anything. Whats your opinion? Peer pressure dosnt influence me in the least.
