Which Drinks Are Most Likely to Give You the Worst Hangover?
We’ve all been there. You wake up after a night out, and your head is pounding, your mouth feels like cotton, and your body aches like you’ve been hit by a truck. While the simple truth is that drinking too much of any alcohol can leave you feeling miserable, some drinks are far worse for your morning-after recovery than others. The science behind this comes down to a few key factors—primarily, substances called congeners and the often-overlooked role of sugar.
The Science Behind the Suffering: Congeners
The main culprit behind a hangover is ethanol—the pure alcohol in drinks . However, during fermentation and aging, various byproducts called congeners are created. These chemical compounds include substances like methanol, tannins, and histamines, which contribute to the unique taste, aroma, and color of different alcoholic drinks .
While the alcohol itself is the primary cause of a hangover, congeners play a significant role in making it worse . When you consume a drink high in congeners, your body must break down these additional toxins alongside the ethanol, which can slow the entire process down . Research confirms that drinks high in congeners produce more severe hangover symptoms compared to drinks that have very few of them .
The Worst Offenders: Dark Spirits
Based on the evidence, the drinks most likely to give you the worst hangovers are dark spirits.
Bourbon, whiskey, brandy, and dark rum are loaded with congeners, especially if they have been aged in wooden barrels, which introduce additional compounds . Bourbon, in particular, has been singled out by experts as a “known hangover bomb” because of its high congener levels . A study published in Current Drug Abuse Reviews found that bourbon contains 37 times more congeners than vodka . In controlled studies where participants consumed the same amount of alcohol, bourbon drinkers reported more severe next-day symptoms than vodka drinkers .
Red wine is another major culprit. It is high in congeners and also contains tannins and histamines, which can contribute to headaches . Additionally, a compound called quercetin, found in red grapes, may interfere with how the body processes alcohol, potentially making the hangover worse. A 2010 paper even noted that red wine was one of the drinks linked to the most hangover symptoms .
The Dangerous Cocktails and Sugar Trap
It is not just the base spirit that matters; the mixers can also turn a bad situation into a horrible one.
Sugar is a major contributing factor to how you feel the next day . A sugar crash on top of a hangover is a brutal combination . Experts point out that sugary mixers mask the strong flavor of alcohol, leading you to drink more without realizing it . This can deplete your body’s hydration and B vitamins, making you feel worse .
A “sugar hangover” can also occur independently of alcohol. Consuming more than the recommended daily limit of sugar (24 grams for women and 36 grams for men) can cause a spike and subsequent crash in blood sugar levels, leading to symptoms like brain fog, fatigue, and headaches within a few hours .
The “Best” Choice: Clear Spirits
If you are planning a night out and want to minimize the risk of a severe hangover, your best bet is to choose clear spirits, particularly vodka.
Vodka is almost entirely pure ethanol and water, containing very few congeners . Gin and unaged rum are also good lower-congener options . However, it’s important to note that the color of your drink doesn’t make it “healthy.” The core issue remains the amount of alcohol you consume .
Conclusion: The Golden Rules
While avoiding congeners and sugar can reduce your risk, the most important factor remains the total amount of alcohol you drink. To avoid feeling terrible the next morning, follow these simple guidelines:
Choose clear spirits like vodka or gin.
Use low-sugar mixers like soda water.
Hydrate: Drink a glass of water between alcoholic beverages .
Eat: Have a good meal before you start drinking.
Moderate: No drink is safe if you overconsume .
