Did Coffee Really Suppress Sexual Desire?

Ever heard the claim that coffee kills your sex drive—or was even favored by monks trying to suppress desire? That idea wasn’t just gossip; it shaped early opinions of coffee in Europe. So, can a cup of coffee actually dull your impulses, or was that just historical fear talking?

No, coffee does not suppress sexual ability. The 17th-century belief that it did was rooted in religious and cultural fears of bodily pleasure, not scientific evidence. Historical texts like those by Max Weber discuss how Puritans viewed sex even within marriage as purely for procreation—not pleasure—framing coffee as a tool for discipline rather than a proven appetite suppressant.

The Monk’s Drink and London’s First Coffeehouse

There was a time when coffee was thought to kill libido so effectively that it became the preferred drink of monks committed to celibacy. Given that belief, it’s remarkable that London’s very first coffeehouse opened around 1688. While today we might worry coffee kills desire, 17th-century Brits were more afraid of losing control to lust. Cultural anxiety, not biology, shaped early views of caffeine’s effects.

Coffee vs. Beer: A Battle of Substances

In the 16th and 17th centuries, beer was a dietary staple. According to Cambridge University Press’s Food, Energy and Leisure in English Agricultural History, by the late 1500s, male mill workers drank an average of 4 quarts (about 4.5 liters) of beer per day, while women consumed about half that. Beer was seen as nourishing, even essential—essentially, liquid food. Coffee, in contrast, provided negligible calories and was never a meal replacement.

Coffee only gained traction once food supplies were more secure. Its appeal wasn’t nutritional—it was functional. Most notably, it helped sober people up. Unlike beer or wine, coffee didn’t dull the senses but sharpened them. This quality gave coffee an edge in a society increasingly interested in clarity and self-control.

Coffee as a Tool of Sobriety and Discipline

Sylvester Dufour, who wrote extensively on beverages in the late 1600s, noted in The Manners of Taking Tea, Coffee and Chocolate that coffee was initially served as a hangover cure alongside wine and spirits. Its role on the table marked a shift: the decline of alcohol’s dominance and the rise of a new kind of drinking experience—one linked to wakefulness, restraint, and a new ethic of productivity. This helped cement coffee’s reputation as the sober, serious alternative to intoxicants.

Early proponents framed coffee as a way to manage the body’s baser instincts. The idea wasn’t that caffeine chemically suppressed libido, but that it symbolically supported a lifestyle of discipline. In the context of rising Protestant ethics, particularly those described by Max Weber in The Protestant Ethic and the Spirit of Capitalism, even marital sex was seen as a means to an end—procreation—not enjoyment. In this worldview, managing physical urges—including through diet—was both a spiritual and economic concern.

Why Did People Link Coffee to Lost Libido?

The notion that coffee could reduce sexual desire likely stemmed from a simple mind-body dualism: the idea that the spirit should dominate the flesh. Since coffee replaced beer—a drink tied to indulgence and bodily relaxation—it was seen as morally and physically purer. The lower calorie count and stimulating effects of coffee further distanced it from the nourishing, soporific qualities of alcohol. In short, coffee wasn’t proven to suppress libido, but it symbolized a rejection of indulgence.

Frequently Asked Questions

Did monks really drink coffee to suppress sexual urges?

The idea that monks drank coffee to suppress desire was a cultural belief, not a documented practice. Coffee gained a reputation in the 17th century as a drink that could cool passions, leading to the myth that it was favored by those seeking chastity. There’s no evidence that monks systematically used it for that purpose.

Was coffee believed to cause impotence in the 1600s?

Yes, some 17th-century Europeans feared that coffee could reduce sexual ability or desire. This belief was tied to broader anxieties about self-control and the body’s appetites, especially among those who valued religious discipline and sobriety over indulgence.

What did people drink instead of coffee before it became popular?

Before coffee rose in popularity, especially in 17th-century Europe, beer was a daily staple for most people, including laborers. Men drank up to 4.5 liters per day, and it was considered nutritious—more like food than a beverage. Wine and spirits were also common, but coffee emerged as a sober alternative.

How was coffee first introduced in European social settings?

Coffee was first served in Europe as a sobering drink, often alongside wine and spirits. Sylvester Dufour noted in the late 1600s that it helped people recover from drunkenness. Its initial role was practical—restoring clarity—before it became a social beverage.

Is there any proof that coffee reduces sex drive?

No scientific evidence from the 17th century or modern research supports the idea that coffee reduces sex drive. The belief was based on cultural and religious attitudes toward bodily pleasures, not on caffeine’s actual physiological effects on libido.
