Unfortunately, your daughter doesn't have much of a defense. Minor in Possession and Minor Consumption are two different offenses. Since your daughter was charged with the former, it doesn't matter that she had not opened the beer, or consumed no alcohol.
Generally, though, MIP is not usually considered a big deal, especially in college towns. Odds are pretty good that your daughter will be eligible for some sort of pre-trial diversion program or, at worst, a suspended sentence with probation and coummunity service, plus a fine and costs.
Of course, there are always variations in state or local laws, as well as variations in what, for lack of a better word, I'll call "local custom" that may have an effect on your daughter's situation.
For that reason, I would recommend that you contact your local bar association’s lawyer referral service (they all have them) to locate a lawyer who practices criminal law in your state.

I would also appreciate any feedback you can give me to improve the quality of my answers.
