Did Early Europeans Believe Coffee Killed Libido?

Imagine walking into London’s first coffeehouse around 1688, knowing some believed the very drink in your hand could make you lose interest in sex—or worse, ruin your ability to perform. That wasn’t just a fringe idea; it was a widespread belief in early 17th-century England, rooted in deep cultural fears about bodily urges.

No, coffee does not suppress sexual desire. Historical accounts from the 1600s claimed it did, especially among those promoting abstinence—but modern understanding shows no evidence supports this. The fear was cultural, not physiological.

The 17th-Century Fear of Coffee and Sex

When coffee first arrived in Europe in the early 1600s, it quickly spread across the continent. In Britain, one of the oddest early beliefs was that coffee curbed libido—some even said drinking too much could make you impotent. This idea made coffee oddly appealing to monks and others who practiced celibacy. The notion was tied to broader anxieties about the body and self-control, especially in a society increasingly shaped by Protestant ethics.

A Society Afraid of Its Own Desires

According to Max Weber in “The Protestant Ethic and the Spirit of Capitalism,” 17th-century British Protestants—especially Calvinist-leaning Puritans—viewed sexuality strictly through a utilitarian lens. Even within marriage, sex was seen primarily as a means for procreation, not pleasure. The body was a tool for labor and devotion, and managing physical urges—including hunger, tiredness, and lust—was both a spiritual and economic concern. In this context, coffee’s reputation as a sobering, mind-sharpening drink fit neatly into a culture that prized discipline over indulgence.

Beer vs. Coffee: A Battle of Substances

To understand why coffee was suspected of dulling desire, you have to look at what it replaced. Beer was a staple drink in 16th- and 17th-century Europe, consumed in huge quantities daily. According to Cambridge University Press’s “Food, Energy and Leisure in English Agricultural History,” male mill workers in the late 1500s drank an average of 4 quarts (about 4.5 liters) of beer per day, while women drank about half that. Beer was considered nourishing, even a food-like substance. Coffee, by contrast, had negligible calories and wasn’t seen as sustenance at all. It could only gain popularity once food supplies were more stable, and it was valued more for its mental effects than its nutritional ones.

Coffee’s big selling point? It woke you up. Especially after a night of drinking, coffee helped people sober up. Sylvester Dufour, who wrote several books on beverages in the late 1600s, noted that coffee originally appeared on tables alongside wine and spirits—not as a luxury, but as an antidote. It marked the beginning of a shift away from alcohol-dominated drinking culture and introduced a new value system centered on clarity, sobriety, and alertness.

Why Did People Link Coffee to Lost Libido?

The idea that coffee suppressed sexual desire likely stemmed from simple dualist thinking: the body must be subordinate to the mind or spirit. Since coffee came to replace beer—a drink long associated with physical pleasure and communal indulgence—it was easy to frame it as a purer, more ascetic alternative. Coffee didn’t just wake you up; it symbolized control over carnal instincts. That made it especially attractive to religious groups that promoted abstemiousness. But there was no scientific basis for the claim—just cultural projection.

What Really Happened When People Drank Coffee?

Rather than suppressing desire, coffee’s most immediate effect was heightened wakefulness. It helped people shake off drunkenness and stay alert during long workdays. Over time, it became associated with productivity, rationality, and self-discipline. None of these traits inherently diminish sexual appetite, but in a society obsessed with controlling base instincts, those effects were easily misread as threats to carnality.

Why did people in 17th-century England think coffee reduced sex drive?
