From the Guidelines
One standard drink is typically considered to be approximately 44 mL of 80 proof (40%) spirits, 355 mL of 5% beer, or 148 mL of 12% wine, which corresponds to about 14 grams of pure alcohol or 17.7 mL of ethanol. The volume of a standard drink can vary depending on the type of alcoholic beverage and its concentration. For instance, beer (5% alcohol) is usually around 355 mL (12 oz) per standard drink, wine (12% alcohol) is about 148 mL (5 oz), and distilled spirits or liquor (40% alcohol) is approximately 44 mL (1.5 oz) per standard drink 1. It's essential to understand these measurements to monitor alcohol consumption and adhere to recommended drinking guidelines. Different countries may have varying definitions of a standard drink, such as the UK with 8 grams of alcohol and Australia with 10 grams 1.
The most recent guideline from the American Heart Association emphasizes the importance of recognizing substance use, including alcohol, as a significant contributor to cardiovascular disease risk and outcomes 1. This guideline highlights the need for simple screening questions to identify unhealthy alcohol use, which can lead to premature or recurrent cardiovascular events. Understanding standard drink sizes is crucial for making informed decisions about alcohol consumption and staying within recommended limits for health and safety.
Key points to consider:
- The volume of a standard drink varies by type of beverage and concentration
- Standard drink sizes are essential for monitoring alcohol consumption and following drinking guidelines
- Different countries may define standard drinks differently
- Recognizing and addressing unhealthy alcohol use is critical for reducing cardiovascular disease risk and outcomes 1
From the Research
Volume of a Standard Drink
- The volume of a standard drink in milliliters (mL) is not explicitly stated in the provided studies 2, 3, 4, 5, 6.
- However, it is mentioned that a standard drink typically contains 10 g of ethyl alcohol 3, 5, 6.
- The study 6 defines the standard drink unit (SDU) for Spain as containing about 10 g of pure alcohol, which is equivalent to 1 beer, 1 glass of wine, or a half measure of spirits.
- The exact volume of a standard drink in mL is not provided, but it can be inferred that it varies depending on the type and strength of the beverage 5, 6.
