What Is Cafestol? The Cholesterol-Raising Compound in Coffee

If you've ever wondered why some coffee drinkers report changes in cholesterol readings, the answer might be hiding in their brewing method—not their beans. Certain styles of coffee are unexpectedly high in a natural compound that can raise serum cholesterol levels, and it’s not caffeine. The culprit? A little-known lipid called cafestol.

Cafestol is found in high amounts in unfiltered coffee—such as Turkish or French press—and almost none in filtered brews. A single cup of unfiltered coffee may contain 6–12 mg of cafestol, while filtered coffee has just 0.2–0.6 mg. That difference explains why your brewing choice could affect more than just taste.

What Is Cafestol?

Cafestol is a diterpene compound naturally present in coffee beans. Alongside kahweol—its close relative—it belongs to a group of oily, fat-soluble substances that dissolve into hot water during brewing but are trapped by paper filters. You won’t find either in instant coffee or drip-filtered coffee in any meaningful amount.

Why Does Cafestol Matter?

In the 1980s, researchers discovered that drinking unfiltered coffee could raise serum cholesterol levels. Further studies identified cafestol and kahweol as the compounds responsible. These diterpenes interfere with cholesterol metabolism, specifically by reducing the liver’s ability to clear low-density lipoprotein (LDL), often referred to as “bad” cholesterol.

Of the two, cafestol is the more potent agent. A daily intake of 60 mg of cafestol (or a mix of 60 mg cafestol and 51 mg kahweol) raises serum cholesterol more significantly than 64 mg of cafestol alone. Although kahweol also affects cholesterol, its instability and difficulty to isolate have made its individual effects harder to confirm.

How Much Cafestol Is in Your Coffee?

The concentration of cafestol depends on both the coffee variety and brewing method:

• Arabica beans contain both cafestol and kahweol, making up around 1% of the bean’s total composition.
• Robusta beans have roughly half the cafestol of Arabica and almost no kahweol.

When it comes to brewing, the method determines how much of these compounds make it into your cup:

• Unfiltered methods such as Turkish coffee, French press, and Scandinavian boiled coffee contain 6–12 mg of cafestol per cup, as the oily compounds are not captured by a filter.
• Espresso (especially from a steam-driven moka pot) has moderate levels—about 4 mg per cup—due to the small serving size.
• Filtered coffee (including pour-over, drip, and AeroPress with paper filters) and instant coffee contain only 0.2–0.6 mg per cup, because the paper traps the diterpenes.

Does Your Brewing Method Increase Cholesterol Risk?

If you drink several cups of unfiltered coffee daily, especially Turkish or French press, you’re likely consuming enough cafestol to affect your blood lipid levels over time. Switching to a paper-filtered method can dramatically reduce your cafestol intake while keeping your coffee ritual intact.

Frequently Asked Questions

What is cafestol in coffee?

Cafestol is a natural diterpene compound found in coffee beans. It is fat-soluble and dissolves into hot water during brewing, but is mostly removed by paper filters. Unfiltered coffee contains much higher levels of cafestol.

Does filtered coffee contain cafestol?

Very little. Filtered coffee methods—like pour-over, drip, or AeroPress with paper filters—remove nearly all cafestol, leaving only 0.2–0.6 mg per cup. That’s significantly less than unfiltered brews.

Which coffee brewing methods have the most cafestol?

Turkish coffee, French press, and Scandinavian-style boiled coffee have the highest cafestol content, about 6–12 mg per cup, because they don’t use paper filters to trap the compound.

Is cafestol bad for your health?

Cafestol can raise serum cholesterol levels by interfering with how the body processes LDL cholesterol. Regular consumption of unfiltered coffee with high cafestol content may impact heart health over time.

Does espresso have cafestol?

Yes, but in smaller amounts. A typical espresso shot contains around 4 mg of cafestol. While not as high as Turkish coffee, it’s still more than filtered coffee due to the lack of a paper filter.

Why doesn’t instant coffee have cafestol?

Instant coffee is made from brewed coffee that has already been filtered, usually with industrial processes that remove cafestol. As a result, it contains minimal amounts—around 0.2–0.6 mg per cup.
