Espresso is synonymous with the pinnacle of coffee brewing and holds a unique place in the world of coffee, defined by the Specialty Coffee Association standard of 9 bars of pressure. Often misunderstood as a concept, espresso is the cornerstone of the coffee shop menu. Can you brew espresso at home without a machine? This article explores what constitutes brewed espresso and how you can achieve it using manual techniques like a Moka pot or French press.
Espresso is frequently misunderstood, with many coffee lovers confusing it with alternatives such as Moka pot or French press brews. (the SCA-standard 9-bar espresso definition) This article aims to clarify these misconceptions and emphasize the unique qualities of true espresso, particularly the importance of pressure and proper tamp technique in its preparation.
What Is Espresso?
Espresso refers to both a brewing method and the resulting beverage. It is a concentrated shot of coffee brewed by forcing hot water through finely ground coffee beans under high pressure—typically 9 bars, as defined by the Specialty Coffee Association. This pressure, combined with precise temperature control and a consistent tamp, extracts rich flavors and aromas, resulting in a strong and intense beverage. We have an article that explains in more detail what espresso is, if you want to dive deeper into the subject.
What Is Brewed Espresso?
Brewed espresso is often misunderstood as a strong drip coffee, an alternative to true espresso. The confusion arises from the term “brewed.” Often, drip coffee is referred to as brewed coffee, leading people to associate the word “brewed” with drip coffee.
In reality, all coffee is brewed. According to extraction science research published in Journal of Food Science, the coffee extraction process is called brewing. You can brew a cup of French press, a shot of espresso, or a jar of cold brew.
So brewing an espresso shot means preparing an espresso.
Brewed espresso doesn’t mean an espresso prepared using the drip coffee brewing method. In fact, we will show later in the article why strong drip coffee is the worst espresso alternative. And since we brought up the subject, don’t worry, there are other decent alternatives to replicate an espresso, and I’ll show you what those are.
For the purpose of this article, we might use the term “brewed espresso” to refer to espresso alternatives, because it makes it easier to communicate, but everywhere else on this website we call these “espresso alternatives“.
The most important thing to learn is that “brewed espresso” cannot truly replicate the unique characteristics of a genuine espresso shot. You can replicate espresso’s strength when brewing alternatives, but almost every other flavor and sensory aspect—such as crema, mouthfeel, and balanced extraction—will lack.
Is this so bad? It depends on who you ask. If you ask an espresso aficionado, they’ll tell you that only an espresso machine with a proper portafilter and consistent tamp will do it. But if you ask the majority of Italians who make a cappuccino at home using their macchinetta, they’ll say it is their perfect morning cup of coffee.
The Best Espresso Brewing Alternatives – Brewed Espresso without a Machine
While a true espresso shot requires a specialized machine to generate the SCA-standard 9 bars of pressure, there are alternative brewing methods that can produce a similar taste and texture. These methods include the French Press, AeroPress, and Moka Pot. Each technique offers a distinct approach to crafting espresso-based drinks and serves as an acceptable substitute for a neat espresso shot. We’ll guide you on how to incorporate these methods into your espresso routine, focusing on proper grind size, water temperature, and extraction time.
The French Press
The French Press is a popular brewing method that can create a coffee beverage with a taste and strength akin to espresso. As an immersion method, it is forgiving and full-bodied, as described by coffee expert James Hoffmann. By using a fine grind and a longer brew time, the French Press can extract the flavorful oils and compounds from the coffee grounds, resulting in a concentrated and robust cup. You may also use a bit more coffee grounds to achieve a stronger flavor. However, do not increase your dose by more than 25% of the recipe, as it will result in a bitter and tannic taste due to over-extraction.
While the French Press is a viable alternative, the Moka Pot and AeroPress are the brewing methods most recommended by baristas for replicating an espresso experience. Both devices require a consistent burr grinder to achieve the fine, uniform grind necessary for optimal extraction.
AeroPress
The AeroPress is widely regarded as an excellent espresso alternative, having its own World AeroPress Championship and extensive reviews by James Hoffmann. This portable and versatile device utilizes air pressure to push hot water through finely ground coffee, producing a rich and flavorful cup. Although the pressure doesn’t reach the 9-bar level required for authentic espresso, it effectively creates a close approximation. AeroPress coffee is milder than traditional espresso, making it a great substitute for a neat shot. It can also be used in espresso-based drinks, though the coffee flavor will be more subdued. For best results, use a medium-dark roast and a fine grind setting.

Moka Pot
The Moka Pot, also known as a stovetop espresso maker, is a traditional Italian brewing method that can produce a coffee beverage with a taste and texture similar to espresso. As described by coffee authorities Lance Hedrick and James Hoffmann, it produces a concentrated, espresso-like coffee using steam pressure to extract flavors from the coffee grounds. Proper tamping of the coffee grounds in the filter basket is essential for even extraction and a balanced shot. The Moka Pot creates a strong and concentrated shot of coffee, though it lacks the crema of true espresso.
The Moka Pot coffee is probably the best alternative for preparing cappuccino and latte. However, the coffee doesn’t have the same strength and concentration as genuine espresso, so you’ll need to adjust your milk quantity to prevent diluting it excessively. A typical ratio is one part Moka Pot coffee to two parts steamed milk for a balanced latte.

What Makes True Espresso Unique
Espresso is unique in several ways, but if we have to choose the key differences versus regular coffee, the brewing method and the concentration of flavors are the most significant. According to the Specialty Coffee Association (SCA), true espresso is defined by a precise set of parameters, including a brew ratio of 1:1.5 to 1:2.5 and extraction under 9 bars of pressure.
While regular coffee is brewed by simply pouring hot water over coarser coffee grounds, espresso involves a more intricate process that requires high pressure and finely ground coffee. The result is a concentrated shot of coffee that offers a unique flavor profile and a more intense caffeine concentration per unit volume.
From a sensory perspective, espresso is the most concentrated coffee. It has a thick consistency, and the flavors are very intense. The layer of crema on top of the beverage is a sign of a well-prepared shot, indicating proper extraction and fresh coffee.
Caffeine Content
There is a popular belief that espresso has more caffeine than regular coffee, which is actually false. Espresso has a higher caffeine concentration than regular coffee, but per serving, espresso has a lower caffeine content. A typical single shot contains approximately 63 mg of caffeine, compared to 95 mg in an 8-ounce cup of drip coffee.
Technical Differences
True espresso is prepared using strict parameters defined by the SCA. Most of these parameters are dictated by the unique method of brewing coffee under pressure, which requires precise control over every variable to achieve the desired result.
Because we use pressure during the extraction, all of the variables need to concur to obtain a certain resistance in the coffee puck, otherwise the pressure will do nothing. At the industry-standard 9 bars of pressure, the coffee puck must be properly tamped and evenly distributed to create uniform resistance and prevent channeling.
These factors include grind size, water temperature, brew time, and dose, as outlined by Scott Rao in The Professional Barista’s Handbook. There are more espresso variables, but for the purpose of this article, these are the most important ones. Here is an article that talks about espresso extraction in more details: Extraction and Espresso Brewing – A Guide to Coffee Perfection
Pressure
The key technical difference between espresso and regular coffee is the pressure used during brewing. Espresso is the only coffee brewing method that uses high pressure during the coffee extraction. The pressure speeds up the extraction, thus reducing the quantity of some compounds that would make your coffee taste bitter and tannic. This rapid extraction under pressure is what distinguishes espresso from all other brewing methods.
True espresso requires an espresso machine. An espresso machine is a special equipment, that can generate at least 9 bars of pressure. The portafilter holds the coffee grounds and distributes the pressurized water evenly through the puck, a design unique to espresso brewing.
The pressure applied during espresso brewing significantly influences the extraction of flavors from coffee grounds. When brewed at 9 bar pressure, water effectively saturates the coffee grounds, extracting more flavors and creating a thick layer of crema. The espresso beverage is renowned for its rich flavor profile, which includes notes of caramel, chocolate, and fruit depending on the roast and origin.
Grind size
Unlike regular drip coffee, which uses a medium grind, espresso brewing requires a much finer grind for optimal extraction. A quality burr grinder is essential for achieving the consistent particle size needed for proper extraction. If the grind is too coarse, water passes through too quickly without extracting sufficient flavors. Conversely, if the grind is too fine, excessive resistance in the coffee puck prevents water flow. While grind size is a technical requirement, it dramatically affects the sensory experience of your coffee cup.
From a sensory perspective, a very fine grind size also contributes to a shorter extraction time. By reducing the extraction time, we avoid drawing out undesirable compounds. Finer grinds also introduce more suspended microparticles into the final cup. These fines enhance the thickness of the espresso shot and contribute to its distinctive mouthfeel, creating a velvety texture that lingers on the palate.
Water Temperature
The water temperature should be carefully maintained between 195°F and 205°F (90°C to 96°C) to maximize the extraction of flavors and aromas while minimizing the risk of over-extraction. If the temperature is too low, insufficient extraction occurs, resulting in a weak taste. If the temperature is too high, over-extraction can occur, leading to an unpleasant, burnt flavor.
The extraction temperature for espresso is similar to other coffee brewing methods, typically ranging between 195-205°F, according to the Specialty Coffee Association. This consistency ensures optimal extraction but doesn’t drastically differentiate espresso from other methods in terms of temperature. What sets espresso apart is how temperature interacts with pressure and fine grind to produce a concentrated shot.
Brew Time
Espresso brew time is notably shorter than other brewing methods, with an ideal range between 20 and 30 seconds. The combination of pressure and fine grind size accelerates the extraction process, making espresso unique. According to James Hoffmann, this rapid extraction is a defining characteristic of espresso, as it preserves delicate aromatic compounds that would otherwise degrade.
Compared to drip coffee, espresso contains fewer tannins, which are the compounds responsible for astringency. This absence is crucial because it explains why drip coffee cannot be brewed to espresso strength without altering its flavor profile. The high-pressure extraction of espresso minimizes tannin extraction while maximizing desirable flavor compounds.
Dose
The amount of coffee grounds used for an espresso shot is referred to as the dose. For a single shot, the dose is typically 7 grams of coffee grounds, with a possible variation of 1 gram depending on the manufacturer. A double espresso shot generally requires 14 grams, though this can slightly vary by manufacturer. Experienced baristas often adjust the dose slightly to compensate for roast freshness or grind consistency.
In North America, the double shot is the most popular espresso serving, while in Italy, the single shot is more commonly preferred. Although the dose for espresso is generally fixed, experienced baristas may adjust it to refine their shots, particularly when working with different roast levels or coffee origins.
While espresso dosing is precise, the dose for drip coffee is more flexible, allowing for personal taste preferences. Similarly, French press dosing is adaptable, whereas AeroPress and Moka pot, which are excellent espresso alternatives, require stricter dosing to achieve consistent results. Understanding these dosing differences helps home brewers select the right method for their preferences.
The Misunderstood Concept of “Strong Coffee” as Espresso
A common misconception is that espresso is merely a stronger coffee. While espresso is indeed strong, not all strong coffees qualify as genuine espresso. The strength of coffee does not equate to its resemblance to espresso, as noted by Scott Rao in “The Professional Barista’s Handbook.”
Even if you brew a drip coffee using more coffee grounds, it will not replicate the complex flavors, the mouthfeel, or the crema that are characteristic of true espresso. (the SCA-standard 9-bar espresso definition) A strong cup of coffee is not the same as espresso.
If you talk to a barista and you say that you’d like to have an espresso, they’ll warm up their espresso machine to pull a shot. (recognized by the Specialty Coffee Association (SCA))
For instance, there is no such thing as cold brew espresso, and we talk about it in a separate article. (cold-brew extraction parameters, for which the Specialty Coffee Association has published recommended guidelines) Cold brew coffee is not a pressure brewing method. The brewing process for espresso is unique, and that’s what makes it an espresso, not just the strength of the drink.
Why You Can’t Brew Espresso with a Drip Coffee Maker
Attempting to brew espresso with a drip coffee maker is futile. Drip coffee makers lack the necessary pressure to extract the flavors and create the signature crema of espresso. Additionally, the grind size used for drip coffee is much coarser than what is required for espresso, resulting in a weaker and less concentrated beverage.
Espresso Beans
If you ever thought that using “espresso beans” with your drip coffee maker will give you an espresso shot, I’m here to bear the bad news. There is no such a thing as espresso beans.
This coffee beans choice is the least restrictive factor. You can use any coffee beans to brew your espresso, or espresso alternative. Dark roasts will extract easier, while lighter roasts will extract harder. We have an article where we discuss how to choose coffee beans for espresso. It is a deeper dive into the subject, if you need it.
At the end of the day, any type of coffee is acceptable for brewing espresso, it all depends on your personal preference. Personal taste is what drives coffee beans choice, in both cases true espresso or brewed espresso.
Conclusion
In conclusion, while there are many ways to enjoy coffee, it’s important to remember that true espresso is unique and cannot be replicated by other brewing methods. The key message we want to drive home is that true espresso needs 9 bar pressure for proper extraction, a standard defined by the Specialty Coffee Association.
We encourage all coffee lovers to explore the world of espresso and appreciate the unique characteristics that sets it apart.
