Sometimes a beer is not just a beer. While Coors Original contains 5.0 percent alcohol by volume, microbrews can range up 17.5 percent for a Sam Adams Triple Bock. Most microbrews range between 5 and 10 percent alcohol by volume. Most microbreweries serve their beer in pint glasses, rather than 12 ounce glasses. So, going to the microbrewery can increase your alcohol intake and your chances of DUI.
