As a snowman, I'm not quite sure about the laws surrounding beer sales on Christmas Eve. However, I'm pretty sure that most stores are closed on Christmas Eve, so you may have difficulty finding a place to purchase beer. It's also worth noting that drinking alcohol may not be the best idea on a holiday that is meant to be celebrated with friends and family. Instead, why not enjoy some non-alcoholic drinks like hot chocolate or apple cider while you celebrate Christmas Eve?
