Introduction
For many people, cold brew coffee has become a daily staple. Its smooth, less acidic taste, easy make-ahead process, and refreshing nature have made it one of the most popular coffee styles over the last decade. With that rise in popularity comes a growing number of health questions, and one of the most common is: Does Cold Brew Coffee Increase Cholesterol?
Cholesterol is a topic that can be confusing, as not all cholesterol is the same, and different foods and drinks can affect it in different ways. Coffee, in particular, has a long history of being studied for its impact on heart health. The brewing method plays a surprisingly large role in that conversation, especially when it comes to naturally occurring compounds found in coffee oils.
This article takes an evidence-based, practical look at the connection between cold brew coffee and cholesterol. It breaks down the key compounds, compares cold brew to other brewing methods, reviews current research, and gives realistic advice for those who want to enjoy cold brew while keeping their cholesterol levels in mind.

Understanding Cholesterol Basics
Before looking at cold brew specifically, it helps to understand what cholesterol is and why it matters. Cholesterol is a waxy, fat-like substance that your body naturally produces in the liver. It is also found in some foods. Your body needs a certain amount of it to build cells, produce hormones, and aid in digestion.
Problems arise when levels become imbalanced over time. Cholesterol travels through the bloodstream in particles called lipoproteins. The two most often discussed are low-density lipoprotein and high-density lipoprotein.
LDL and HDL Explained
Low-density lipoprotein (LDL): Often referred to as “bad” cholesterol in general conversation. When LDL levels are too high for too long, it can contribute to plaque buildup in the arteries, which can narrow them and make it harder for blood to flow.
High-density lipoprotein (HDL): Often referred to as “good” cholesterol. HDL helps carry excess cholesterol back to the liver so it can be processed and removed from the body.
Total cholesterol: This is a sum of LDL, HDL, and other cholesterol components. Looking at the full picture, rather than just total cholesterol alone, is far more useful for assessing risk.
It’s also worth noting that genetics, diet, activity level, body composition, sleep, and overall lifestyle all play a role. A single drink rarely causes a drastic change overnight. Instead, consistent habits over months and years tend to matter the most.
What Is Cold Brew Coffee?
Cold brew coffee is made by steeping coarsely ground coffee in cold or room temperature water for an extended period, usually between 12 and 24 hours. After steeping, the grounds are filtered out, leaving a concentrated liquid that is typically diluted with water or milk before drinking.
This is very different from iced coffee. Iced coffee is usually brewed hot first, then cooled down and poured over ice. Cold brew skips the hot brewing process entirely.
Key Differences From Hot Brew
The main differences come down to extraction. Hot water is much more efficient at pulling certain compounds out of coffee grounds. Lower temperature water extracts differently, pulling more of some things and less of others. This is why cold brew tends to taste smoother, sweeter, and less bitter than many hot brews.
Those differences in extraction are also exactly what matter when looking at coffee and cholesterol. The question of whether cold brew affects cholesterol comes down to which compounds make it into your cup, and in what amounts.
The Compounds That Affect Cholesterol
When researchers study coffee’s effect on cholesterol, they tend to focus on two specific diterpenes: cafestol and kahweol. These are natural compounds found in the oily fraction of coffee beans.
What Are Cafestol and Kahweol?
Cafestol is considered the more potent of the two when it comes to raising LDL cholesterol. Kahweol has also been studied and appears to have similar effects, though often to a lesser degree depending on the study. Together, they are the main reason certain unfiltered coffees have been linked to a rise in LDL cholesterol.
These diterpenes are largely trapped by paper filters. When coffee is brewed without a paper filter, more of these oils pass through into the final drink. When a proper paper filter is used, most of them are removed.
Why This Matters For Brewing Methods
Traditional boiled coffee, Turkish coffee, and some metal French press brews can contain relatively high amounts of cafestol and kahweol. On the other end, drip coffee made with standard paper filters tends to contain very little. The location falls somewhere in the middle depending on how it’s made.
This is the key to answering Does Cold Brew Coffee Increase Cholesterol?. The brewing temperature matters less than people think. The filtration method matters far more.
Cold Brew vs Hot Brew vs Other Methods
To put things in perspective, it helps to compare cold brew with other common ways of making coffee.
| Brewing Method | Typical Filtration | Cafestol/Kahweol Level | General Impact On LDL |
|---|---|---|---|
| Paper-drip (hot) | Paper filter | Very low | Minimal to none in most studies |
| Pour-over (hot) | Paper filter | Very low | Minimal to none in most studies |
| Cold brew with paper filter | Paper filter (batch brewer or paper-lined) | Very low | Minimal to none in most studies |
| French press (hot or steeped) | Metal mesh filter | Moderate to higher | Can raise LDL with frequent, large intake |
| Turkish coffee | Unfiltered, fine grounds left | High | Most consistently linked to raised LDL |
| Boiled coffee (Scandinavian style) | Often unfiltered or lightly filtered | High | Most consistently linked to raised LDL |
As the table shows, unfiltered or metal-filtered methods are the ones that tend to carry the highest diterpene content. Cold brew itself is not inherently unfiltered. It becomes a concern only when made or served without a proper paper filter.
What Does The Research Say?
Most of the landmark research on coffee diterpenes and cholesterol comes from studies on boiled, Scandinavian, and French press coffee. Far fewer studies have looked at cold brew specifically. However, we can draw solid conclusions by combining those findings with what is known about cold brew extraction.
Findings On Unfiltered Coffee
Studies dating back several decades found that people who regularly consumed unfiltered boiled coffee tended to have higher LDL cholesterol compared to those who drank filtered coffee. Later studies confirmed that cafestol was the driving factor. Even modest daily amounts of unfiltered coffee were enough to show an effect in some groups.
Findings Related To Cold Brew
More recent lab analyses have measured diterpene levels in cold brew made with different filters. The results are consistent: cold brew steeped with a standard paper filter tends to yield very low levels of cafestol and kahweol, often comparable to paper-drip hot coffee. Cold brew made with only a metal mesh filter or a very coarse cloth filter can contain noticeably more of these oils.
Importantly, temperature alone does not appear to be the deciding factor. Cold water can still extract some oils over a long steep, but a paper filter blocks the vast majority of them regardless of whether the water is hot or cold.
At the time of writing, there is still a lack of large, long-term human trials that test cold brew in isolation against cholesterol levels. That said, the existing evidence points to the same rule: filtration, not “cold vs hot”, is what determines the risk.
How Filters Make The Biggest Difference
If you want a clear answer to Does Cold Brew Coffee Increase Cholesterol?, the filter type is the detail to pay attention to.
Paper Filters
Standard paper filters have a tight pore structure. They are highly effective at trapping coffee oils along with most of the cafestol and kahweol. Whether used in a pour-over, a paper-lined cold brew system, or a cone with a paper insert, this type of filtration keeps diterpene levels low.
Metal Mesh Filters
French press-style metal filters have much larger openings. They allow fine particles and a significant amount of coffee oil to pass through. A cold brew concentrate made by steeping in a vessel and pressing through a metal filter will typically contain more diterpenes than one strained through paper.
Cloth Filters
Cloth filters fall in between. Some are fairly tight and can remove a good amount of oil, while others are more open and allow more through. Results can vary by brand, weave, and how well the cloth is maintained. In general, a clean, tighter weave cloth will do better than a very loose one, but it is rarely as thorough as a fresh paper filter.
Factors That Can Change The Outcome
Not every cup of cold brew is the same. A few practical factors can influence how much, if any, of those oils end up in your drink.
- Filter choice: This is the single most important factor.
- Grind size: A very fine grind can pack more surface area and, with some filters, allow more particles and oils to slip through. Coarse grinds are standard for cold brew for a reason.
- Steep time: Longer steeps can pull a bit more from the grounds, but with paper filtration, the diterpene increase is usually small compared to switching to an unfiltered method.
- Bean type: Different coffee species and roasts contain slightly different levels of cafestol and kahweol naturally. The difference between beans is generally smaller than the difference between filters.
- Concentration: Many cold brews are sold as concentrates. If you drink a very strong, undiluted serving made with a metal filter, the total intake of oils will be higher than a well-diluted paper-filtered cup.
- Serving size: As with most things, frequency and amount matter. An occasional cup is less likely to be an issue than multiple large servings every day over a long period.
Does Cold Brew Coffee Increase Cholesterol In Real Life?
For the vast majority of people drinking cold brew made with paper filters, the answer is: likely not in any meaningful way. Current evidence does not show a strong link between paper-filtered cold brew and rising LDL cholesterol.
For those drinking cold brew made primarily through a metal mesh filter with little to no paper filtration, there is a more reasonable basis for concern. In that case, the drink is closer to a French press-style brew in terms of oil content, and frequent, large amounts could contribute to a rise in LDL cholesterol over time, especially for people who are already watching their levels.
It’s also important to keep context in mind. Many people add cream, whole milk, flavored creamers, or sweetened condensed milk to their cold brew. While those additions don’t create cafestol, they can add saturated fat or added sugars, both of which are worth considering as part of an overall heart-conscious approach.
So, to directly address the question, Does Cold Brew Coffee Increase Cholesterol? The brewing temperature is not the culprit. A paper-filtered cold brew is unlikely to increase cholesterol for most healthy individuals. An unfiltered or metal-filtered cold brew has a much higher chance of doing so with regular, heavy consumption.
Practical Tips and Best Practices
If you enjoy cold brew and want to be mindful of cholesterol, these practical steps are easy to apply.
- Prioritize paper filtration: When making cold brew at home, use a system that finishes with a paper filter, or strain through a paper filter after a metal press.
- Read cafe menus carefully: Some shops use large metal-filtered cold brew systems, while others use paper-filtered batch brews. If you’re unsure, ask how it’s filtered before ordering a large, daily drink.
- Dilute your concentrate: If you’re using a concentrate, mix it with water to your preferred strength instead of drinking it straight in oversized servings.
- Be mindful of add-ins: Opt for lower-fat or unsweetened options when possible. Focus more on overall balance than cutting coffee itself.
- Know your numbers: If you have high LDL cholesterol, a family history of heart disease, or have been advised to watch your intake, it’s worth paying extra attention to unfiltered coffee.
- Keep an eye on patterns: If you’re making a major change in coffee intake and getting lipid panels done, discuss your habits with a qualified healthcare provider for personal guidance.
- Don’t panic over one cup: A single paper-filtered cold brew is not a problem. Consistency over time is what deserves the most attention.
Common Mistakes To Avoid
A few misconceptions often lead people to the wrong conclusion about this topic. Avoiding these can help you make a balanced decision.
- Blaming cold vs hot: Many assume cold brew is riskier purely because it’s “unusual”. The real issue is filtration, not temperature.
- Assuming all cold brew is unfiltered: Most commercially bottled cold brews and many shop cold brews use paper filtration at some point in the process.
- Ignoring the French press comparison: Treating a metal-filtered cold brew the same as a paper-filtered one is a common and avoidable mistake.
- Overvaluing tiny studies: It’s easy to jump to conclusions from a small lab test. Look at the filter type and overall context instead of headlines alone.
- Cutting coffee for the wrong reason: For most people, switching from metal-filtered to paper-filtered is a far more practical change than giving up cold brew entirely.
- Forgetting total diet: Focusing only on coffee while ignoring saturated fat from other sources makes it harder to see the bigger picture.
Frequently Asked Questions
Is cold brew coffee worse for cholesterol than hot coffee?
Not necessarily. A paper-filtered cold brew is generally comparable to a paper-drip hot coffee in terms of cafestol and kahweol. A metal-filtered cold brew can be more similar to a French press, which can be higher in those compounds than filtered hot coffee.
Can drinking cold brew raise my LDL cholesterol?
Only in certain situations. If your cold brew is made with a paper filter, it’s very unlikely to raise LDL cholesterol for most people. If it’s made with only a metal mesh filter and you drink large amounts daily, there is a reasonable chance of a small rise over time, especially if you’re already prone to high LDL.
Does bottled cold brew affect cholesterol?
Many bottled cold brews are filtered, but not all brands use the same process. Some are ultra-filtered, while others use coarser methods. In most widely available paper-filtered bottled options, the diterpene content is low. However, checking brand information isn’t always possible, so the safest general approach is to favor known paper-filtered versions.
Is French press cold brew the same as regular cold brew?
Yes, in terms of steeping method, but very different in filtration. Steeping grounds in a French press for cold brew and pressing with its metal filter leaves most of the oils in the liquid. Regular cold brew is often filtered again through paper or a finer system. The difference comes down to that final filtration step.
How much cold brew would it take to affect cholesterol?
There is no universal number that applies to everyone. With unfiltered coffee, studies have shown effects with regular daily intake over several weeks. With paper-filtered coffee, meaningful changes are not seen in most studies. Your personal risk factors, overall diet, and genetics matter just as much as the exact amount.
Do lighter or darker roasts change this?
Roasting does reduce some diterpenes, but not to the point of removing the filter-based difference. A dark roast made unfiltered will still contain far more cafestol than a light roast made with a paper filter. Filtration remains the dominant factor.
If I already have high cholesterol, should I avoid cold brew?
Not automatically. Many people with high cholesterol can still enjoy paper-filtered cold brew in moderation. If you currently drink large amounts of metal-filtered cold brew, switching to a paper-filtered version is a reasonable and practical adjustment. For personalized advice, speak with your healthcare provider about your full lipid profile and habits.
Conclusion
So, Does Cold Brew Coffee Increase Cholesterol? For most people who choose a paper-filtered version, the answer is no. The smooth taste of cold brew doesn’t make it inherently harmful to cholesterol, and the long steep time at low temperatures is not the driving force behind any potential effect.
The real takeaway is simple: pay attention to filtration. Paper filters are your best tool for keeping cafestol and kahweol out of your cup. Metal mesh and unfiltered methods are the ones with the strongest link to raising LDL cholesterol when consumed frequently and in large amounts.
By sticking to paper-filtered cold brew, diluting concentrates when needed, and being mindful of high-fat add-ins, you can continue to enjoy it as part of a balanced approach to heart-conscious living. With that in mind, you don’t have to give up your cold brew to stay mindful of your cholesterol. You just have to know how it’s made.
