Alcohol is a depressant that affects everyone differently. It impacts judgment and inhibitions while slowing reaction times. The amount of alcohol in a drink depends on the alcohol content, or percentage of alcohol by volume (ABV). In the US, the standard drink size is defined as 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80-proof distilled spirits, all of which contain about 0.6 ounces of pure alcohol. With this knowledge, we can explore whether 20 ounces of 80-proof alcohol is considered excessive.
| Characteristics | Values |
|---|---|
| Amount of 80-proof alcohol in oz. | 1.5 oz. |
| Amount of alcohol in grams | 14 grams |
| Equivalent amount of pure alcohol in other drinks | 12 oz. of beer, 5 oz. of wine |
| Percentage of alcohol by volume | 40% |

What You'll Learn
What is a standard drink?
The definition of a standard drink varies from country to country. Generally, a standard drink is defined as any beverage containing a specified amount of pure alcohol, typically measured in grams or fluid ounces. This amount can range from 8 to 20 grams of pure alcohol, with the World Health Organization's Alcohol Use Disorders Identification Test (AUDIT) defining a standard drink as 10 grams (0.35 ounces).
In the United States, a standard drink is defined as containing 0.6 US fluid ounces (approximately 18 milliliters) or 14 grams of pure alcohol. This amount is often used as a guideline for health recommendations. To put it into context, a 12-US-fluid-ounce can of 5% beer, a 5-US-fluid-ounce glass of 12% ABV wine, or a 1.5-US-fluid-ounce "shot" of 80-proof spirit would each constitute one standard drink. It's important to note that the actual alcohol content in these beverages may vary, and the standard drink definition is based on average values.
In Australia, the standard drink is also commonly used. For example, a 375-milliliter can of full-strength beer (4.8% alcohol) is considered 1.4 Australian standard drinks. Similarly, a "medium" glass of 12% ABV wine (175 milliliters) contains around 2.1 UK units of alcohol, which is approximately equivalent to 2 Australian standard drinks.
The UK also has its own unit system, where one UK unit of alcohol is defined as 10 milliliters or 8 grams. This is roughly equivalent to a third of a pint of low-strength beer, a small glass of lower-strength wine, or a single measure of spirits. It's important to note that the serving sizes in pubs and restaurants may be larger than these standard drink definitions.
Understanding standard drink sizes is essential for monitoring alcohol consumption and its potential health impacts. Excessive alcohol consumption can lead to serious health issues, and the liver can only process a limited amount of alcohol at a time. The rate at which alcohol is metabolized can vary depending on factors such as body weight, gender, age, metabolic rate, food intake, and the type and strength of the alcohol. Therefore, it's important to be mindful of standard drink sizes and to drink responsibly.

How is alcohol absorbed into the body?
Alcohol is a depressant drug that enters the body through the digestive system. When alcohol is consumed, it first enters the stomach, where about 20% of it is absorbed into the bloodstream. The remaining 80% passes into the small intestine, where it is absorbed much faster due to the larger surface area available for absorption. The epithelial cells that line the stomach and small intestine have finger-like projections that increase the surface area for absorption.
The pyloric valve, which separates the stomach from the small intestine, closes when food is present in the stomach, especially protein-rich and fatty foods. This slows down the absorption of alcohol into the bloodstream, as the alcohol cannot move into the small intestine immediately. Eating while drinking can therefore help to slow intoxication.
Once alcohol is absorbed into the bloodstream, it is carried by the blood into the veins, where it can be distributed throughout the entire circulation. The small size of alcohol molecules, specifically ethanol, allows them to pass easily through the endothelial cell membrane walls of the capillaries. These endothelial cells are loosely packed together, with small holes called fenestrae that further facilitate the passage of alcohol molecules.
From the capillaries, alcohol enters the veins and is distributed throughout the body. Most tissues, such as the heart, brain, and muscles, are exposed to similar concentrations of alcohol as the blood. However, the liver, which metabolizes more than 90% of the alcohol, receives blood directly from the stomach and small bowel, resulting in higher exposure to alcohol. The liver metabolizes alcohol at a constant rate of approximately one drink per hour, and excessive alcohol in the blood can lead to intoxication as unmetabolized alcohol continues to circulate in the bloodstream.
The rate of alcohol absorption and its effects on the body can vary depending on several factors, including gender, mood, and whether it is consumed on an empty stomach or with food. Women tend to experience stronger and longer-lasting effects due to higher levels of estrogen, higher body fat percentages, and lower levels of body water, which limit alcohol absorption into tissues and keep it in the bloodstream. Men typically have higher levels of enzymes that break down alcohol in the stomach before absorption. Additionally, alcohol is absorbed more quickly on an empty stomach, especially when the concentration is between 20-30%.

How does alcohol affect the body?
Alcohol affects the body in numerous ways, and excessive alcohol consumption can have serious health consequences. Here is a detailed overview of how alcohol affects the body:
Short-term effects
Alcohol is a depressant drug that affects the body's central nervous system. Initially, it may cause a feeling of energy, but it also impairs judgment and inhibitions, slows reaction times, and affects coordination. Alcohol also causes blood vessels to dilate, leading to a drop in body temperature. As the liver prioritizes metabolizing alcohol, blood sugar levels drop, which can cause hunger, nausea, and hangovers. The risk of accidents and injuries also increases due to impaired coordination and judgment.
Long-term effects
Heavy or binge drinking over time can lead to severe health issues. Alcohol misuse is linked to peripheral neuropathy, causing numbness in the arms and legs and painful burning in the feet. It can also result in heart arrhythmias, low blood pressure, diarrhea, and erectile dysfunction. Alcohol interferes with the brain's communication pathways, impacting mood, behavior, and cognitive functions. It increases the risk of stroke and various types of cancer, including breast cancer in women.
Impact on specific organs
- Liver: The liver is responsible for metabolizing alcohol, and excessive drinking can lead to liver inflammation, cirrhosis, and long-term damage.
- Brain: Alcohol interferes with the brain's communication pathways, impacting mood, behavior, and cognitive functions.
- Pancreas: Long-term alcohol misuse can lead to pancreatitis, impairing the production of digestive enzymes and affecting blood sugar regulation.
- Immune System: Drinking alcohol weakens the immune system, making it harder for the body to fight infections and increasing the risk of diseases.
Standard drink sizes and recommendations
It's important to note that a standard drink is typically defined as 12 ounces of beer, 4 ounces of wine, or 1.25 ounces of 80-proof distilled spirits. These drinks contain about 0.6 ounces (14 grams) of pure alcohol. To minimize health risks, it's recommended that men consume no more than two drinks per day and women no more than one drink per day. Binge drinking, defined as consuming multiple drinks in a short period, significantly increases health risks.

How does alcohol content vary across drinks?
Alcohol content varies significantly across different drinks, with some beverages containing very little alcohol and others boasting high alcohol content. The alcohol content of a drink is typically measured in alcohol by volume (ABV), which indicates the percentage of alcohol in the liquid. The higher the ABV of a drink, the quicker you are likely to feel drunk.
Beers, light hard seltzers, and kombucha tend to have lower alcohol percentages. For instance, light beers usually have an ABV ranging from 3% to 4%, while standard lagers typically have an ABV between 4% and 6%. On the other hand, stronger varieties of beer, such as bocks or doppelbocks, can have an ABV exceeding 7%. Similarly, craft beers usually have an ABV ranging from 3% to 5%, but some specialty craft beers may surpass 10% ABV.
Conversely, spirits like vodka, tequila, rum, and whiskey generally have much higher alcohol percentages. The ABV of spirits typically starts at around 20%, but some states allow up to 95% ABV. For example, 80-proof vodka equates to 40% ABV, while 110-proof vodka corresponds to 55% ABV.
Wine alcohol content usually falls between 9% and 14% ABV, unless it is fortified wine, in which case the ABV will be higher. Fortified wines, such as sherry, port, and Madeira, are fortified with brandy or another distilled spirit, resulting in a higher alcohol content.
It is important to note that the "standard drink" measurement can vary by country, which can lead to confusion and unintended consequences. For instance, in the United States, a standard drink is defined as any beverage containing 0.6 fluid ounces or 14 grams of pure alcohol. In Australia, the standard is 10 grams, while in the UK, it is 8 grams.
