Coffee is one of the most widely consumed beverages in the world, however, it contains some substances that could either have good or bad effects on our health. Cafestol, a diterpene molecule found in coffee beans, is one such substance. While some of the distinctive smells and scents in coffee are attributed to cafestol, it is also recognized for its tendency to increase cholesterol.
To remove cafestol from coffee, you should utilize paper filters while brewing to capture the compound. Alternatively, choose espresso machines equipped with metal filters or activated charcoal, which effectively absorb cafestol during the brewing process.
Paper Filters: An Effective and Widely Accessible Solution
Paper filters have been a trusty friend in the art of coffee brewing for decades, providing a simple and extremely effective means of decreasing cafestol levels in the finished cup. To understand how paper filters function, you must first learn about the brewing process. When hot water is poured over ground coffee beans, the soluble chemicals within the beans dissolve, producing a distinctive coffee fragrance and flavor. Cafestol, a diterpene molecule that contributes to coffee’s distinct flavor profile, is one of these chemicals.
Cafestol, on the other hand, has sparked worry due to its potential impact on cholesterol levels. According to some research, cafestol may raise low-density lipoprotein (LDL) cholesterol, sometimes known as “bad” cholesterol, which could harm cardiovascular health if ingested in large amounts. As a result, people who are health-conscious or have special dietary limitations may look for ways to reduce their cafestol intake while still enjoying their regular cups of coffee.
Here’s when paper filters come in handy. Paper filters, which are made of porous cellulose fibers, operate as a physical barrier throughout the brewing process. The many soluble chemicals included in coffee, including cafestol, are extracted as hot water filters through the coffee grounds. The tiny cafestol molecules, on the other hand, come into contact with the paper filter’s grid of minuscule pores, which function as a sieve to capture and keep them back.
The paper filter efficiently prevents cafestol from getting through, ensuring that the cafestol remains restricted within the coffee grounds and that only the filtered liquid, known as the brew, makes its way into the carafe. The result is a smooth, sediment-free cup of coffee with a much lower cafestol level than unfiltered coffee.
The appeal of utilizing paper filters is not just their capacity to reduce cafestol levels, but also their broad availability and simplicity of usage. Paper filters, which come in a variety of shapes and sizes, are compatible with the majority of coffee brewing systems, from traditional drip machines to pour-over settings. Because of their low cost and ease of disposal, they are an excellent choice for both home and commercial coffee brewing.
Paper filters are a fantastic choice for individuals looking for a simple way to limit cafestol intake without sacrificing taste. Other methods, like metal filters in espresso machines or activated charcoal, may present exciting alternatives for coffee enthusiasts who desire a more nuanced and powerful flavor experience.
Traditional espresso machines have been outfitted with metal filters in pursuit of the perfect espresso shot. Metal filters, as opposed to paper filters, allow some of the coffee’s natural oils, notably cafestol, to pass through. This improves the body and flavor of the espresso, producing a richer, more aromatic brew.
Modern espresso machines, on the other hand, come with finer metal filters for people who want to balance their love of the espresso experience with a reduction in cafestol intake. These upgraded filters are meant to retain more of the coffee’s oils while still efficiently reducing the cafestol concentration in the final espresso shot. As a result, they provide a happy medium that allows coffee lovers to enjoy the best of both worlds.
Aside from paper and metal filters, a relatively modern and novel method of removing cafestol involves the use of activated charcoal. Because activated charcoal is a highly porous substance with a large surface area, it is an efficient adsorbent capable of trapping a variety of chemicals, including cafestol.
Activated charcoal can be integrated into disposable filter papers or placed within the brewing device to include it in the coffee brewing process. The cafestol molecules are adsorbed and trapped on the porous surface of the charcoal as hot water runs through the charcoal or the charcoal-infused paper filter.
While activated charcoal has shown potential in lowering cafestol levels, there is one catch. Some coffee connoisseurs say that its use may affect the flavor profile of the coffee. Because activated charcoal can adsorb not only cafestol but also other desirable flavor components, the resulting coffee brew may have a somewhat different flavor than standard brewing methods.

Espresso Machines with Metal Filters: A Step Beyond
The development of espresso machines has transformed the coffee-drinking experience for coffee connoisseurs all around the world. These machines are well-known for their capacity to generate espresso, a concentrated and tasty coffee. Metal filters have always been an essential part of the espresso brewing process.
Metal filters in espresso machines are coarser in texture than paper filters, which operate as a barrier to prevent cafestol and coffee oils from flowing through. This permits some of the natural oils in the coffee, such as cafestol, to freely flow into the finished espresso shot. As a result, the body and flavor of the coffee are boosted, resulting in a richer and more aromatic beverage that many coffee enthusiasts enjoy.
While the addition of oils enhances the overall attractiveness of espresso, it may be a worry for those wanting to minimize their cafestol consumption. Cafestol, as previously stated, is a diterpene chemical present in coffee beans that has been linked to the ability to elevate LDL cholesterol levels. As people become more health-conscious, many coffee drinkers are looking for ways to enjoy their beloved beverage without compromising their cholesterol levels.
Modern espresso machine makers have added finer metal filters to address these concerns. These filters are specifically engineered to preserve more of the natural oils found in coffee, including cafestol, while lowering its overall presence in the finished espresso shot. This careful mix is intended to appeal to people who want to limit their cafestol intake without sacrificing the flavor complexity and richness that comes from the coffee’s oils.
The idea behind these upgraded metal filters is to strike a balance between caffeine reduction and flavor preservation. Coffee enthusiasts can relish an espresso that strikes the appropriate mix between taste and health considerations by allowing some oils to get through while simultaneously decreasing cafestol concentration.
The availability of newer espresso machines with finer metal filters is a great advancement for cafestol-conscious coffee enthusiasts. This innovation ensures that people can still enjoy the pleasures of a rich espresso without overdosing on Cafestol.
While using finer metal filters can reduce cafestol levels, it may not eliminate the chemical from the coffee. Individuals with unique health concerns should therefore seek specialized advice on coffee use from their healthcare specialists.
As coffee science and technology evolve, espresso machine makers are constantly looking for methods to improve the brewing process to meet the different needs of their customers. The development of finer metal filters illustrates this dedication to improving coffee quality while also addressing health-related concerns.
Activated Charcoal: A Novel Approach
Utilizing activated charcoal in the pursuit of a healthy cup of joe has been a fascinating trend in recent years in the world of coffee drinkers and researchers. The renowned cafestol, a substance included in coffee that may have harmful effects on health, particularly cholesterol levels, has been the subject of attention. The investigation of activated charcoal as a potential remedy to absorb and lessen the amount of cafestol was prompted by this.
Due to its enormous surface area and high porosity, activated charcoal has long been known for its capacity to trap a variety of chemicals. Its special qualities have been used in a variety of industries, from medicine to air and water cleaning. Now that it has expanded into the area of making coffee, there are more options for creating a healthier brew.
It is relatively simple to use activated charcoal in the coffee-making process. It can be cleverly incorporated into disposable filter sheets or put right inside the brewing apparatus. During the brewing process, hot water is added, and it seeps through the porous surface of the charcoal or the paper filter that has been treated with charcoal. The surface of the charcoal traps and holds the cafestol molecules that are present in the coffee as this infusion takes place, producing a brew with a substantially lower cafestol level.
This novel method has drawn interest due to both its possible health advantages and its effect on the end product’s flavor and aroma. Some coffee connoisseurs contend that adding activated charcoal improves the sensory experience overall by giving the coffee a smoother, less bitter flavor.
However, the use of activated charcoal in coffee production is not without difficulties and disagreements, just like any other scientific endeavor. Some detractors express concern over the potential removal of advantageous components in addition to cafestol, which would change the beverage’s overall nutritional profile. Finding the ideal balance between getting rid of negative components and keeping the positive ones is still a crucial part of this field’s ongoing research.
Comparing the Methods: Taste and Convenience
The level of convenience desired and one’s taste preferences are key considerations when deciding how to remove cafestol from coffee. The accessibility and user-friendliness of paper filters make them a desirable choice for many coffee drinkers. Paper filters, which are widely available and reasonably priced, effortlessly provide a clean, smooth cup of coffee with little sediment and less cafestol. The fact that they are disposable makes cleaning up after brewing easier, which increases their attractiveness.
On the other hand, people who enjoy the powerful and rich flavors that espresso machines may provide might favor metal filters. More of the coffee’s natural oils are retained by these filters, giving the brew a fuller-bodied and more powerful flavor. Choosing finer metal filters is a smart move for enthusiasts who value the true espresso experience. These filters efficiently lower the amount of cafestol while allowing more of the vital coffee oils to flow through, producing an espresso-like beverage.
Activated charcoal is effective at adsorbing cafestol, however, its use in coffee filters may not be as widespread as it may be. Its propensity to affect the flavor profile of the coffee is an important factor. While activated charcoal could introduce small changes that discriminating palates may not find acceptable, paper and metal filters maintain the integrity of the coffee’s flavor. Adding activated charcoal to the brewing routine could require a little more difficult procedure, making it less practical than the simple use of paper or metal filters.

Hi! I’m Shawn Chun
My adventure in coffee began when I first launched my first coffee shop back in the early 2000s. I had to figure out so many things on my own and to make it worse within 2 years of opening two large corporate coffee chains moved in just blocks away from me!
As I saw smaller and even some larger coffee shops in the neighborhood slowly lose customers to these giant coffee chains and slowly close up shop, I knew that I had to start getting creative…or go out of business.
I (like you may be) knew the coffee industry well. I could make the best latte art around and the foam on my caps was the fluffiest you have ever seen. I even had the best state-of-the-art 2 group digital Nuova Simonelli machine money could buy. But I knew that these things alone would not be enough to lure customers away from the name brand established coffee shops.
Eventually, through lots of trial and error as well as perseverance and creativity I did find a way to not only survive but also thrive in the coffee/espresso industry even while those corporate coffee chains stayed put. During those years I learned to adapt and always faced new challenges. It was not always easy, however, in the end, I was the sole survivor independent coffee shop within a 10-mile radius of my location. Just two corporate coffee chains and I were left after that year. All told the corporate coffee chains took down over 15 small independent coffee shops and kiosks and I was the last one standing and thriving.
Along the years I meet others with the same passion for coffee and I quickly learned that it is not only “how good a barista is” that makes a coffee shop successful, but the business side of coffee as well.
Hence why I started this website you are on now. To provide the tools and resources for up and coming coffee shop owners to gain that vital insight and knowledge on how to start a coffee shop successfully.
Stick around, browse through my helpful blog and resources and enjoy your stay! With lots of LATTE LOVE!
Shawn
