When comparing alcoholic beverages, what two factors must be known?

To determine how different alcoholic beverages compare in terms of their effects and intoxication, it's crucial to know the size of the drink and its alcohol content. The size of the drink helps identify the volume being consumed, while the alcohol content, usually indicated as a percentage of alcohol by volume (ABV), informs how much pure alcohol is present in that drink.

This information is essential for understanding blood alcohol concentration (BAC) and making informed decisions about drinking. For example, a larger drink with a high alcohol content will have a more significant impact on intoxication levels than a smaller drink with less alcohol. Therefore, knowing both the size of the drink and the alcohol content allows for an accurate assessment of the risks associated with consuming different types of alcoholic beverages.
