The primary effect of serving size on alcohol consumption is that it influences blood alcohol concentration. When a person consumes larger servings of alcohol, they are likely to ingest a higher amount of alcohol in a shorter time frame, which can lead to a more significant rise in blood alcohol concentration (BAC). This is critical because BAC directly impacts a person's level of impairment and risk for harm.

Depending on the serving size, even small changes can result in notable differences in how intoxicated a person becomes. For example, a larger cocktail or a larger beer will introduce more alcohol into the bloodstream compared to standard servings, thereby affecting the individual's abilities and responses.

While serving size can indeed play a role in how quickly a drink is consumed and can influence taste perception, its most critical impact lies in how it affects BAC, making it the central focus in understanding alcohol consumption and the resulting risks.
