Coffee can increase cholesterol, but the effect depends almost entirely on how you brew it, not the caffeine.
Unfiltered coffee—French press, Turkish, Greek, boiled, and some espresso styles—can raise LDL and total cholesterol, while paper-filtered drip coffee usually does not. The difference comes down to two oily compounds called diterpenes that paper filters catch. For most US coffee drinkers, the fix is simpler than quitting coffee: change the brewing method, not the habit.
Why Unfiltered Coffee Raises Cholesterol
Coffee beans contain cafestol and kahweol, two diterpenes that interfere with how the liver clears LDL cholesterol. When you brew coffee without a paper filter, these oils end up in your cup. A paper filter traps most of them before they reach your mug.
Controlled human studies back this up. That same study, published in the BMJ, is one of the clearest demonstrations that the brewing method—not coffee itself—drives the effect.
The practical takeaway: if your daily cup comes from a French press or a pot of boiled cowboy coffee, your LDL may creep up over time. If it comes from a standard drip machine with a paper filter, your lipids likely stay put.
Which Brewing Methods Are Safe And Which Are Not
The chart below breaks down the common brewing methods by their cholesterol impact. The pattern is consistent: anything brewed without a filter carries the diterpenes; anything filtered or instant does not.
| Brewing Method | Filtered? | Cholesterol Effect |
|---|---|---|
| Paper-filtered drip | Yes | Minimal or none in most studies |
| Instant coffee | N/A | Negligible—very low in diterpenes |
| French press | No | Raises LDL and total cholesterol |
| Turkish / Greek | No | Raises LDL and total cholesterol |
| Boiled / cowboy | No | Raises LDL and total cholesterol—the strongest effect |
| Moka pot (stovetop espresso) | No | Likely raises cholesterol; findings mixed |
| Espresso (café) | No | Mixed evidence; 3–5 cups daily linked to higher cholesterol |
But that effect is small compared with the unfiltered numbers.
What About Espresso And Moka Pot Coffee?
Espresso is the gray zone. Some studies show no significant lipid changes from moka-style espresso, but more recent observational data links 3–5 cups per day of espresso with higher total cholesterol. Because espresso is brewed without a paper filter, the diterpenes are present—just in smaller amounts per serving than in boiled coffee.
If you drink espresso daily, the dose matters. A single shot now and then is unlikely to move your numbers. A daily quad latte made on a home espresso machine is a different story, especially if your diet is already heavy on saturated fat.
Should You Switch For Your Heart?
For people with high LDL, familial hypercholesterolemia, or established heart disease, review literature specifically advises choosing brews low in diterpenes. That means paper-filtered drip, pour-over, or instant coffee over French press, Turkish, or boiled styles.
Switching methods is the highest-impact change you can make without giving up coffee. Keep in mind that individual response varies—some people see bigger lipid shifts than others from the same brew. If you are managing cholesterol with medication or diet, it is worth mentioning your coffee habit to your clinician. They can tell you whether a brewing change matters for your specific profile.
The other thing the evidence does not support: blaming caffeine. The cholesterol effect comes from coffee oils, not caffeine. Decaf unfiltered coffee raises cholesterol about the same as regular unfiltered coffee, because both carry the diterpenes.

FAQs
Is decaf coffee safer for cholesterol than regular?
Not necessarily. The cholesterol-raising compounds in coffee are cafestol and kahweol, which come from the bean’s oils, not the caffeine. Decaf brewed the same unfiltered way—French press, Turkish, or boiled—carries about the same diterpene load as regular coffee and can affect cholesterol similarly.
How much unfiltered coffee is too much?
There is no universal threshold, but the risk scales with volume. One review noted that the effect is dose-dependent: the more unfiltered coffee you drink regularly, the greater your chance of seeing LDL rise. Occasional French press use is unlikely to matter; daily large servings are where the risk concentrates.
Does adding milk or cream change the cholesterol effect?
No. Dairy additions do not remove cafestol or kahweol from the brew. The diterpenes are already in the cup from the brewing process, and milk or cream only adds its own saturated fat. If you use an unfiltered method, the cholesterol impact comes from the coffee itself, not the add-ins.
