Confidential information should not be disclosed in this Internet forum. This answer is not legal advice, which requires a personal connection and far more facts. This attorney does not give legal advice over the Internet. This is a general statement about law, not advice.
You should plead not guilty and get an attorney to review your case. Without reviewing the police report and other evidence any prediction would be deeply flawed, however based on the limited information provided your story does not seem credible. The Judge does not need scientific evidence to convict you of underage drinking. Here the police officer's testimony that you smelled of alcohol is sufficient when coupled with conduct like giving a false name is likely sufficient.
