                                According to the Centers for Disease Control and Prevention, a standard drink contains 0.6 fluid ounces (14 grams) of pure alcohol. For distilled spirits like vodka, whiskey, or gin, this is equivalent to a 1.5-ounce shot of 40% alcohol by volume (ABV). Many people underestimate the amount of alcohol in their drinks, particularly when it comes to cocktails or freely poured servings.
