The Hangover Puzzle: Why Different Alcoholic Drinks Affect You Differently

Ever wake up after a night out with a pounding headache, dry mouth, and a general sense of regret? Hangovers are the dreaded consequence of a fun night, but did you know that not all alcoholic drinks are equal when it comes to the severity of your hangover? Let’s dive into the science behind why some drinks leave you feeling worse than others the next morning.


Ethanol: The Main Culprit

The primary hangover-inducing ingredient in all alcoholic beverages is ethanol, also known as ethyl alcohol. It's the main type of alcohol we drink and is the largest contributor to hangover symptoms simply because it is consumed in the largest quantity. Since ethanol is present in all alcoholic drinks, it provides a constant baseline for hangover severity across different beverages.


The Sweet Side: Sugar's Sneaky Role

Sugar is a significant component in many alcoholic drinks, especially in mixed cocktails. While the sugar itself might not directly cause a hangover, it can lead to low blood sugar the morning after drinking, which mimics hangover symptoms. This combination of alcohol and sugar can leave you feeling even worse as your body struggles to regulate your blood sugar levels after a night of indulgence.


The Myth of the "One Drink" Hangover

It's a common refrain: "Tequila gives me the worst hangovers!" However, this often has more to do with the quantity consumed than the type of alcohol itself. Tequila is frequently associated with heavy drinking sessions and multiple rounds of shots, leading to more severe hangover symptoms. If you drink the exact same amount of one type of alcohol or another and compare the hangover severity between them there is likely to be a difference. Let's get into that in the next section. 


Congeners: Methanol, The Real Hangover Villain (that you can do something about)

The key difference in hangover severity between different types of alcohol lies in congeners. These are compounds produced during the fermentation process, with methanol being the most notorious with regards to hangover severity. Congeners add flavor and aroma to alcoholic beverages but some, with methanol being the most studied in relation to hangovers, also contribute to hangover symptoms. Generally, lighter-colored drinks contain less methanol, making them less likely to cause a severe hangover. For example, vodka and beer have significantly lower methanol content compared to brandy and rum.


Here's a comparison of methanol content in various drinks:


Alcohol

Approximate Methanol Per Liter (mg)

Estimate Methanol Per Drink

Beer

27 

13 mg per pint

Vodka

102 

5 mg per shot

Wine

151 

23 mg per glass

Whiskey

328

14 mg per shot

Gin

500 

22 mg per shot

Tequila

3,000 

132 mg per shot

Rum

3,633

160 mg per shot

Brandy

4,776 

210 mg per shot


This difference in methanol content explains why you might feel worse after a night of drinking dark liquors compared to lighter ones.


The Mixing Myth: Does It Make Hangovers Worse?

You've probably heard the saying, "Liquor before beer, you're in the clear; beer before liquor, never been sicker." However, mixing different types of alcohol doesn't inherently make a hangover worse. What it does do is increase the variety of drinks consumed, which often includes those higher in congeners. Mixing drinks can also lead to drinking more overall, which is a sure recipe for a worse hangover.


Conclusion: Drink Smart, Feel Better

Understanding the different factors that contribute to hangovers can help you make smarter choices about what you drink. Stick to lighter-colored drinks with fewer congeners, be mindful of your sugar intake, and remember that it's often the quantity of alcohol consumed, not the type, that leads to the worst hangover symptoms. So next time you're out, drink smart and your future self will thank you!
