The general guideline is that the body metabolizes alcohol at a rate of about one standard drink per hour, which can vary based on factors like weight, age, and overall health. Therefore, it could take approximately one hour for the body to process the alcohol from each beer consumed. However, this is a rough estimate, and individual metabolism can differ significantly. It's important to remember that drinking habits and the alcohol content of the beverage also play a role in how quickly alcohol is eliminated from the system.
