i'm sure it'd be ok to drink them... my parents went out of town a few weeks ago and i had a party.. we ran outta booze and found bottles of my parents alcohol (beer and mike's hard lemonade)... at the time, we were drunk and only thought they were like two months old... my rents came home and asked what happened to the alcohol we had had for a year and a half (that's the shit we drank).... it had no bad consequences on any of us... so you should be ok.... drink away man!
