                                The Centers for Disease Control and Prevention (CDC) defines a standard alcoholic drink in the United States as containing 0.6 ounces of pure alcohol. This universal measure is vital for understanding alcohol's effects, but the actual liquid volume changes depending on the beverage's potency, especially for higher-proof spirits.
