An espresso machine at its fundamental level applies pressure to hot water and finely-ground coffee to extract a concentrated espresso shot—however, the terminology “pull” is somewhat outdated. Initially, “pull” referred to the action of baristas physically pulling on a spring-loaded lever that activated a piston pushing hot water through a column into the coffee. Nowadays, the majority of espresso machines found in cafes and homes are semi-automatic.
A semi-automatic espresso machine is designed with an electronic button or switch that allows the barista (or home barista) to initiate and terminate the espresso shot. This type of machine provides a user-friendly and cost-effective design, making it simpler to operate compared to manual machines. Additionally, it is generally more economical than automatic and superautomatic machines, which can have a price range of $3,000 to $7,500 for home models.
Things to Consider
So, What Is the Difference Between Semi-Automatic and Automatic Espresso Machines?
Simply put, automatic machines are capable of stopping espresso shots without manual intervention. These machines are commonly found in busy high-end coffee bars where automation aids in keeping the line moving. However, there are also automatic machines available for home use. The internal workings of both types of machines are very similar, except for one significant contrast: automatic espresso machines possess a flow meter. Typically, flow meters utilize a small magnet in the water line to track the rotation count as an espresso shot is being dispensed. This information is then used to consistently pump the same amount of water through the machine for each shot, and can even be programmed down to the exact millimeter. Despite their benefits, accurate flow meters are highly sensitive, costly precision devices, and the majority of commercial espresso machines do not possess them.
Semi-automatic espresso machines depend on the user to manually stop each espresso shot, utilizing a simpler method. Despite needing additional attention, these machines are less expensive, have fewer intricate components, and offer exceptional reliability, thereby making them an ideal choice for a home espresso machine.
Hang on—Aren’t Those Breville Espresso Machines Automatic?
Although technically it is possible, it should be noted that accurate flow meters are both sensitive and expensive, as mentioned earlier. During our testing, we observed that the flow meters in Breville machines lacked precision. It is important to note that espresso recipes require a high level of specificity, as even a small variation of five milliliters of water can significantly impact the overall flavor of a shot. The only machine we have encountered that provides such accuracy is the La Marzocco GS/3, which comes with a price tag of $7,500. Despite this, we still hold a strong liking for these Breville machines. However, we achieved better results when manually stopping the shots ourselves.
In the Intro You Mentioned Superautomatic Machines. What’s Up With Those?
Yes, indeed: the superautomatic espresso machine. If you’ve ever ordered a beverage at a large coffee chain, your drink was made using a commercial, superautomatic machine, although there are also versions available for home use. Superautomatic machines handle all the tasks: simply press a button, and they will grind, measure, compress, and brew. Many of them even have automatic milk frothing capabilities. Due to the numerous components involved, these machines are quite costly (typically around $2,000 for entry-level home models) and can be challenging to maintain. Moreover, without human intervention to determine the amount of water or coffee used, or to adjust the grind setting, the resulting espresso from these machines is usually just acceptable at best. Although they offer the utmost convenience, we believe that the Spinn Coffee Maker, a one-touch brewer utilizing a centrifugal brewing chamber, does a superior job (and at half the price, too).
I Keep Hearing About Dual Boiler Vs. Single Boiler Machines—Does It Really Matter?
Although it may sound like technical terminology, the number of boilers an espresso machine possesses is highly significant. In the case of single boiler machines, only one water boiler is used to heat water for brewing (at approximately 200ºF) and for steaming milk (around 266ºF). Since these two functions require different temperatures, it becomes necessary to alternate between pulling a shot and steaming milk. Some machines, such as the Breville Bambino Plus and the Barista Impress Express, are able to switch between functions relatively quickly. However, the Gaggia Classic Pro takes 45 seconds to heat up and steam milk, which is long enough for the previously pulled espresso shot to oxidize and develop a sour taste. On the other hand, dual boiler machines offer several advantages: the ability to simultaneously pull espresso shots and steam milk, precise temperature control, and enhanced steam power. By utilizing separate boilers for brewing and steaming, both tasks can be completed simultaneously. Additionally, separate steam boilers are typically larger and provide more power, resulting in better textured microfoam for high-quality latte art if desired. However, dual boiler machines do have two major drawbacks: their larger size and significantly higher cost.
What Does PID Stand for and Why Does It Make Better Coffee?
Many machines claim to have a PID controller, but there is limited information available about its actual function. PID stands for “proportional integral derivative” and is an algorithm used to anticipate temperature changes and regulate the boiler accordingly. This technology is commonly found in immersion circulators and high-end toaster ovens to maintain stable temperatures, but it gained popularity in espresso machines through DIY enthusiasts who liked to modify their equipment. Without a PID, the brewing boiler may experience temperature fluctuations of up to 20ºF when the heating cycle starts; however, with a PID, the temperature can be stabilized within a range of 0.1ºF. High temperatures can result in bitter flavors, whereas low temperatures can make shots taste sour. Having a PID in your machine eliminates guesswork and ensures consistently delicious espresso.
Are Expensive Espresso Machines Really Worth It?
Although it is a loaded and personal question, all of our picks can produce delicious espresso and create microfoam in milk. However, the more expensive machines do this task more effectively. It is difficult to quantify how much better they are. The priciest machines on this list are much easier to operate, but beginners may not possess enough knowledge about espresso details to justify the upgrade. Conversely, an experienced individual will find it easier to make a delicious shot with a $500 machine compared to a beginner, but they may desire the accuracy of a more expensive piece of equipment. This guide aims to assist you in balancing the desired features within your budget, and all of these machines are excellent options for home use.
Top 5 Semi-Automatic Espresso Machines
1. Gaggia Classic Pro
If you’re looking for a machine that will heat up in less than 5 minutes, is compact, and requires some manual effort, Gaggia’s Classic Pro is an excellent option.
This machine is a semi-automatic, one level higher than manual makers. All aspects except for water flow and pressure will require your control. This particular machine is suitable for individuals seeking almost complete control over their espresso shots.
Due to its brewing process, making espresso takes more time. However, the machine is equipped with a thermoblock, enabling quick reheating after use. Therefore, individuals desiring a subsequent drink won’t experience prolonged waiting.
The amount of time it takes for the froth steamer to reheat is 30 seconds. This makes it perfect for rapidly frothing milk. With its rotating steam wand, you can have greater control over the foam of your milk, allowing you to customize its texture and taste.
I selected this robust machine made in Italy as the best value because it is built to last and includes all the necessary features of an espresso maker.
By pulling pressure away from the grounds in the portafilter, the 3-way solenoid valve transforms them into a puck. This makes it considerably more convenient to dispose of the coffee grounds. Alternatively, one could arrange nets and engage in a game of hockey.
2. Breville Infuser
The Infuser’s worth is justified by its encompassing quality-of-life features, making it an excellent option for home baristas aiming to extract maximum flavor from their beans. Let me clarify the reasons behind this momentarily.
With its PID digital control technology and thermocoil water heater, your machine is guaranteed to maintain its temperature, making it perfect for achieving a consistent flavor extraction and minimizing waiting time between drinks.
Ideal for individuals seeking a delicious beverage yet desiring to save time for preparing an additional espresso shot.
Another notable feature at this machine’s price point is the pressure gauge, which eliminates the need to rely on intuition and helps you determine the optimal timing for your shot. It greatly enhances comfort and usability.
I recommend many Breville machines in this piece due to their positive reputation for durable machines, making them excellent options for both beginners and experts.
The availability of volumetric control enables the option to select between solo (single) and doppio (double) shots, which means you won’t have to be as concerned about timing your shots.
Maybe you are looking for a smaller machine.
3. De’Longhi Bar
For homes seeking a compact and cost-effective machine compatible with ESE pods, The Bar is a superb choice.
De’Longhi took measures to make sure the price point is excellent. Firstly, they opted for a single boiler instead of a thermoblock, which results in a longer reheat time for the machine after each use.
Not suitable for households with multiple people who drink espresso.
The presence of an “Advanced Cappuccino System” without specifying whether it applies to the machine or just the frother raises doubts. The usage of “Cappuccino” suggests that it pertains to the frother.
The steam wand’s lack of maneuverability makes it less than ideal for those seeking precise control over frothed milk texture. De’Longhi also cut costs by using plastic for the interior of their portafilter.
If you don’t want it to have a shorter lifespan, you might consider investing an additional $60 in an all-metal portafilter. However, this is only necessary unless you are certain about replacing the machine within a year.
If you don’t want to disturb people when making beverages at 5:00 AM, the pump that makes noise is not ideal.
In order to accomplish this, you will require a grinder as well. However, thanks to the Bar’s ESE pod supports, you have the option to substitute them with the machine. This allows you to allocate kitchen space for additional gadgets.
A machine that is more long-lasting may meet your requirements.
4. Breville Bambino Plus
The Bambino Plus, manufactured by a reputable brand of high-quality espresso machines, is ideal for individuals seeking a durable and long-lasting compact machine.
The ThermoJet heater is another remarkable feature that can heat the machine within 3 seconds. This is highly beneficial for individuals in a hurry for work and in need of a relatively fast beverage, or for creating drinks consecutively with minimal waiting time.
The machine’s worth the money solely because of these advantages. Additionally, Breville’s machines have a reputation for being long-lasting, reducing the likelihood of needing a replacement in the near future.
First, the automatic milk texturing feature automates the process of creating microfoam for latte art and beverages that need aerated milk, like lattes. After that, the machine gradually increases its pressure through a low-pressure pre-infusion. This allows for the extraction of more flavors from the coffee beans.
If you choose to buy high-quality espresso beans, it is probable that you will need to also purchase a separate coffee grinder. This grinding equipment will take up a considerable amount of space on your countertop. However, if you prefer to use ESE pods, you will need to buy additional adapter baskets for your portafilter.
Although it comes at a lower cost compared to purchasing a grinder, you sacrifice the option of selecting your own beans by grinding them yourself.
The final issue I have is with the compact drip tray. It has enough space for only one cup and a milk frother container, and nothing more. While this shouldn’t be a major inconvenience for most people, I wanted to find another drawback for this machine.
Are you looking to find a balance between affordability and functionality? Then you will appreciate the following option.
5. De’Longhi Stilosa
If you have enough space on your counter and are in need of a budget-friendly machine that offers all the necessary features, the Stilosa is an excellent option.
With the use of a thermoblock heating unit, the machine is able to heat up much faster than machines with single boilers. However, this feature does not significantly increase the cost of the machine, making it more affordable compared to machines with double boilers. This makes it a great option for individuals who want to prepare multiple beverages without experiencing long waiting times in between.
There are conflicting opinions about De’Longhi. Some people believe it is an excellent company, while others assert that its machines are of poor quality. However, it is worth noting that you are not paying excessively for a machine of good quality.
If the duration of its warranty period is the only time it remains functional, the cost for the included features is not excessively high. This will allow you to have enough time to save money for an upgrade and enhance your skills. If this option is not ideal, read our suggestions for products priced below $200.
When it comes to durability, the portafilter’s inner plastic construction is not ideal for long-term use. If you decide to purchase this maker, I suggest considering a new metal accessory.
While not exceptional, this machine is not a bad deal either.
