The phrase “beer before liquor, never been sicker; liquor before beer, you’re in the clear” has been repeated at parties and bars for generations. This popular drinking rule suggests that the order in which you consume alcoholic beverages can determine whether you’ll wake up with a pounding headache or feel relatively fine the next morning.
But does this age-old saying hold any scientific merit, or is it simply another drinking myth that’s been passed down over time? Let’s examine the evidence behind this claim and explore what actually causes hangovers and how you can minimize their effects.
Understanding the “Beer Before Liquor” Saying
This well-known rhyme has several variations, but the core message remains the same: drinking beer before hard liquor supposedly makes you more likely to experience severe hangover symptoms, while reversing the order allegedly protects you from feeling sick.
The saying has become so ingrained in drinking culture that many people plan their entire evening around it, carefully orchestrating which drinks to consume first to avoid the dreaded next-day hangover.
Where Did This Drinking Rule Come From?
The exact origin of this saying remains unclear, but several theories attempt to explain how it became so widespread:
The Progressive Drinking Theory
One popular explanation is that people typically start their evening with lower-alcohol beverages like beer or wine before gradually moving to stronger drinks as the night progresses. When they inevitably feel sick later that night or the following morning, they attribute their discomfort to the specific drinking order rather than the total amount of alcohol consumed.
The Blood Alcohol Spike Theory
Another theory suggests that hard liquor, with its higher alcohol concentration, causes blood alcohol levels to rise more rapidly compared to beer. According to this hypothesis, ending your evening with liquor after hours of drinking beer could push your already elevated blood alcohol content over the edge, resulting in worse hangover symptoms.
Conversely, the theory proposes that starting with liquor and finishing with beer might slow down the rate at which your blood alcohol levels spike, potentially reducing hangover severity.
The Carbonation Factor
Some believe that beer’s carbonation may cause alcohol to be absorbed more quickly into the bloodstream. If you drink beer after liquor, this supposedly wouldn’t matter as much since you’re already intoxicated. However, starting with carbonated beer might speed up alcohol absorption, making subsequent liquor consumption more intoxicating.
What Science Says About Drinking Order
Despite these seemingly logical explanations, scientific research tells a different story. Studies examining the relationship between drinking order and hangover severity have found little to no evidence supporting this popular belief.
How Alcohol Absorption Actually Works
When you consume alcohol, it begins absorbing into your bloodstream almost immediately upon reaching your stomach and small intestine. The absorption process is typically complete within 30 to 90 minutes after your last drink, well before hangover symptoms begin to appear.
By the time you wake up with a hangover, your body has already absorbed all the alcohol you consumed the previous night, regardless of the order in which you drank different beverages. Your liver has been working throughout the night to metabolize this alcohol at a relatively constant rate of about one standard drink per hour.
Research Findings
A study conducted by researchers examined whether drinking order affected hangover severity. Participants were divided into groups: some drank beer followed by wine, others consumed wine followed by beer, and a control group drank only one type of beverage.
The results showed no significant difference in hangover symptoms based on drinking order. Participants who drank beer before wine experienced similar hangover severity compared to those who drank wine before beer. The only consistent predictor of hangover intensity was the total amount of alcohol consumed and individual factors like body weight, genetics, and tolerance.
What Actually Causes Hangovers?
Understanding what truly causes hangovers can help you make better decisions about drinking. Hangovers result from a combination of factors:
Dehydration
Alcohol is a diuretic, meaning it increases urine production and causes your body to lose fluids faster than normal. This dehydration contributes to many classic hangover symptoms like headache, dizziness, and thirst.
Acetaldehyde Buildup
When your liver breaks down alcohol, it produces acetaldehyde, a toxic compound that can cause nausea, sweating, and rapid heartbeat. Your body normally converts acetaldehyde into harmless substances, but during heavy drinking, it can accumulate and contribute to hangover symptoms.
Inflammation
Alcohol triggers an inflammatory response in your immune system, which can lead to memory problems, decreased appetite, and difficulty concentrating—all common hangover complaints.
Gastrointestinal Irritation
Alcohol increases stomach acid production and can irritate the stomach lining, causing nausea, vomiting, and abdominal pain.
Blood Sugar Disruption
Drinking can interfere with blood sugar regulation, leading to fatigue, weakness, and mood disturbances during a hangover.
Sleep Disturbance
Although alcohol might help you fall asleep initially, it significantly disrupts sleep quality and prevents you from reaching the deeper, more restorative stages of sleep, leaving you feeling exhausted the next day.
Real Factors That Influence Hangover Severity
If drinking order doesn’t matter, what does affect how terrible you’ll feel the next morning? Several evidence-based factors play significant roles:
Total Alcohol Consumption
This is the single most important factor. The more you drink, the worse your hangover is likely to be. There’s no magical drinking order that can overcome the effects of excessive alcohol consumption.
Drinking on an Empty Stomach
Food in your stomach slows alcohol absorption, helping prevent rapid spikes in blood alcohol levels. Drinking without eating allows alcohol to move quickly from your stomach to your small intestine, where it’s absorbed more rapidly into your bloodstream.
Drinking Speed
Consuming alcohol quickly doesn’t give your liver adequate time to metabolize it, leading to higher blood alcohol concentrations and potentially worse hangovers.
Hydration Status
Starting your drinking session already dehydrated, or failing to drink water while consuming alcohol, exacerbates dehydration and worsens hangover symptoms.
Type of Alcohol
Different alcoholic beverages contain varying levels of congeners—toxic compounds produced during fermentation that contribute to hangovers. Darker liquors like whiskey, brandy, and red wine typically contain more congeners than clear spirits like vodka or gin.
Individual Genetics
Your genetic makeup influences how efficiently your body metabolizes alcohol and processes its byproducts. Some people are genetically predisposed to worse hangovers regardless of what or how they drink.
Age
As you age, your body becomes less efficient at processing alcohol, often leading to more severe and longer-lasting hangovers from the same amount of drinking.
Smoking
Research indicates that people who smoke while drinking tend to experience more frequent and severe hangovers compared to non-smokers.
Sleep Quality
Getting adequate rest before drinking and ensuring good sleep afterward can help reduce hangover severity.
Frequency of Drinking
Regular heavy drinkers may develop tolerance to some alcohol effects, but research suggests that repeated heavy drinking can actually increase hangover severity over time.
Evidence-Based Tips to Prevent Hangovers
Since drinking order doesn’t matter, what can you actually do to reduce your risk of a hangover? Here are scientifically-supported strategies:
Moderate Your Consumption
The most effective way to prevent a hangover is to limit how much you drink. Following standard drinking guidelines—no more than one drink per day for women and two for men—significantly reduces hangover risk.
Eat Before and While Drinking
Consuming a substantial meal before your first drink and snacking throughout the evening slows alcohol absorption and helps maintain stable blood sugar levels.
Stay Hydrated
Alternate alcoholic drinks with water, and drink a large glass of water before bed. Proper hydration helps counteract alcohol’s diuretic effects.
Choose Your Drinks Wisely
If you’re prone to hangovers, consider choosing beverages with lower congener content, such as vodka or gin mixed with non-sugary mixers.
Pace Yourself
Limit yourself to no more than one standard drink per hour, giving your liver time to process the alcohol at its natural rate.
Avoid Smoking
Refrain from smoking cigarettes while drinking, as this combination appears to worsen hangover symptoms.
Get Adequate Sleep
Plan for a full night’s rest after drinking to help your body recover. Though alcohol disrupts sleep quality, getting more total sleep time can still help.
Consider Your Drink Strength
Be aware that some mixed drinks and craft beers contain significantly more alcohol than standard servings. A cocktail might contain two or three standard drinks worth of alcohol.
What to Do If You Have a Hangover
Despite your best efforts, you might still end up with a hangover. While there’s no instant cure, these strategies can help you feel better:
Rehydrate
Drink plenty of water or beverages containing electrolytes to combat dehydration.
Eat Nutritious Foods
Gentle, nutritious foods like bananas, eggs, and whole grains can help restore nutrients and stabilize blood sugar.
Rest
Give your body time to recover. Additional sleep can help alleviate symptoms.
Avoid “Hair of the Dog”
Drinking more alcohol to cure a hangover only delays symptoms and can contribute to problematic drinking patterns.
Manage Symptoms Carefully
If you’re considering any medication for symptom relief, consult with a healthcare provider first, as some medications can interact negatively with alcohol still in your system or may irritate an already upset stomach.
The Mystery of Hangover Immunity
Interestingly, research suggests that approximately 20-25% of people who drink alcohol never experience hangovers, regardless of how much they consume or in what order. This appears to be related to genetic factors that affect alcohol metabolism and individual physiological responses to alcohol’s effects on the body.
However, the absence of hangover symptoms doesn’t mean these individuals are immune to alcohol’s other harmful effects, including liver damage, increased cancer risk, and other long-term health consequences of excessive drinking.
When to Be Concerned About Your Drinking
While occasional hangovers after social drinking are common, certain patterns may indicate a more serious issue:
- Drinking more frequently or in larger quantities than intended
- Feeling unable to cut down or control drinking
- Spending significant time drinking or recovering from drinking
- Experiencing strong cravings for alcohol
- Continuing to drink despite negative consequences
- Needing to drink more to achieve the same effects
If you recognize these patterns in yourself or someone you care about, consider speaking with a healthcare provider who can offer guidance and support.
The Bottom Line
The popular saying “beer before liquor, never been sicker; liquor before beer, you’re in the clear” is not supported by scientific evidence. The order in which you consume different types of alcoholic beverages has no significant impact on whether you’ll experience a hangover or how severe it will be.
What truly matters is the total amount of alcohol you consume, how quickly you drink it, whether you eat while drinking, your hydration status, and individual factors like genetics and overall health. The type of alcohol matters somewhat due to congener content, but mixing beer and liquor in either order won’t make a difference if the total alcohol content remains the same.
The most reliable way to avoid a hangover is to drink in moderation, stay hydrated, eat before and during drinking, pace yourself, and get adequate rest. While these strategies may not be as catchy as a rhyming phrase, they’re actually backed by science.
Remember that moderate alcohol consumption is key to minimizing health risks. If you choose to drink, do so responsibly and be mindful of both the short-term effects like hangovers and the potential long-term health consequences of excessive alcohol use.
