Which alcohols cause hangovers?

According to Andrew Huberman, the types of alcohol that are more likely to cause hangovers are influenced by the presence of congeners in the drinks. Congeners are substances that contribute to the flavor and potential hangover effects of different alcoholic beverages. Here is a general hierarchy from his findings:

1. Least Likely to Cause Hangovers:

   • Ethanol diluted in orange juice
   • Vodka
   • Beer

2. Moderately Likely to Cause Hangovers:

   • Gin
   • White wine

3. More Likely to Cause Hangovers:

   • Whiskey
   • Rum
   • Red wine

4. Most Likely to Cause Hangovers:

   • Brandy

This hierarchy suggests that as you go up from ethanol diluted in orange juice to brandy, the potential for hangovers increases, mainly due to the higher levels of congeners in these drinks 1.
