When the temperature hits near freezing, which is better to drink...alcohol or coffee?

You finally landed tickets to the Super Bowl. You and your s/o are planning the trip of a lifetime to see the game in person. The weather forecast calls for snow and a temperature of 25 degrees with a northerly wind of 10 mph at kickoff time. You both are taking insulated clothing to keep the wind off the outside of your body. But, what will keep the inside of your body warm? You only have one of two choices: alcohol or coffee. Question: in cold and freezing weather situations, which will keep your body the warmest…..alcohol or coffee and why?
