A Brief History of Espresso: From Milan to the World

The story of espresso traces its roots back to late 19th-century Milan, Italy, where inventor Angelo Moriondo is credited with developing the first espresso machine. His groundbreaking contraption revolutionized coffee preparation, introducing the concept of forcing hot water through finely-ground coffee at high pressure. This innovative technique yielded a concentrated, intensely flavorful beverage that quickly gained popularity among Milanese coffee enthusiasts.

In 1906, another Italian inventor, Desiderio Pavoni, refined Moriondo’s design, creating the espresso machine that would become the industry standard. Pavoni’s machine, with its lever-operated mechanism, allowed for greater control over the brewing process, further enhancing the quality and consistency of espresso.

From its Milanese origins, espresso’s popularity spread throughout Italy, becoming a cornerstone of Italian café culture. The post-World War II era witnessed espresso’s global expansion, as Italian immigrants introduced their beloved beverage to countries around the world. Today, espresso is ubiquitous in coffee shops, restaurants, and homes, enjoyed by millions daily.

The Science of Espresso: Unveiling the Secrets of a Perfect Cup

The art of crafting the perfect espresso lies in a delicate balance of science and technique. At its core, espresso production involves forcing hot water through finely-ground coffee under high pressure, typically between 9 bars (129 psi) and 15 bars (217 psi). This pressurized passage forces water molecules to extract the flavor compounds and essential oils from the coffee grounds, resulting in a concentrated, intensely flavorful beverage.

Several factors influence the quality of espresso, including the grind size, water temperature, and brewing time. The grind size should be fine enough to allow for proper extraction without clogging the machine, while the water temperature should be between 195°F and 205°F to ensure optimal flavor extraction. The brewing time, typically between 25 and 30 seconds, determines the strength and intensity of the espresso.

Beyond these technical aspects, the art of espresso making lies in the barista’s skill and experience. Baristas must meticulously control every step of the process, from grinding the beans to tamping the grounds to operating the machine, to ensure a consistently delicious and well-balanced espresso.

The Cultural Significance of Espresso: A Global Phenomenon

Espresso has transcended its role as a mere beverage, becoming deeply embedded in various cultures worldwide. In Italy, espresso is a way of life, an integral part of daily social interactions. Italians savor their espresso standing at the bar, engaging in lively conversations and enjoying the vibrant atmosphere of their local cafés.

Espresso’s popularity has extended far beyond its Italian roots, becoming a beloved beverage in countries across the globe. From the bustling cafés of Paris to the trendy coffee shops of New York City, espresso has become a symbol of modern coffee culture, representing a quick, convenient, and flavorful way to start the day or socialize with friends.


With 19 bars of pressure and fast 25 second heat up time, the Crux 17643 Espresso Capsule Coffee Machine makes authentic espresso. It can brew both single and double shots at the touch of a button. The pressure consistently extracts bold, aromatic espresso with thick crema on top. Owners love the simplicity of using Nespresso pods which result in a quality shot every time.

Heating System Explained

The Crux 17643 Espresso Capsule Coffee Machine incorporates a powerful heating element for rapid water heating. Upon pressing the brew button, water passes over the heating element, reaching the ideal extraction temperature within a mere 25 seconds. This design ensures your coffee is consistently hot for optimal flavor.

The Importance of Water Temperature

Several users commented on the coffee’s less-than-ideal temperature. Water temperature is one of the most critical factors in creating a rich and flavorful espresso shot. The ideal water temperature range for espresso extraction lies between 195°F and 205°F. Insufficient temperatures can lead to under-extraction, resulting in weak or overly acidic coffee.

Noise Level:

Multiple reviews do cite the Crux 17643 Espresso Capsule Coffee Machine as louder than comparable single-serve espresso makers. The brewing process itself emits a buzzing noise that some users find irritating. However, the noise is temporary and worth it for the great-tasting espresso produced. The machine is still suitable for office use and won’t wake up the whole household when brewing your morning lattes.


Maintaining the Crux 17643 Espresso Capsule Coffee Machine is simple thanks to the removable drip tray and water reservoir. Users emphasize how easy it is to empty the drip tray and rinse out the water tank as needed. The pieces come out and go back into place seamlessly. A descaling agent is included to flush out the internal tubes and valve systems. Overall, keeping this machine clean is quick and convenient.

User Feedback Analysis

Reviews for the Crux 17643 Espresso Capsule Coffee Machine are mixed, averaging 3.4 out of 5 stars. Satisfied customers praise its compact size, fast heat up time, and authentic espresso comparable to expensive machines. Many love the simplicity of popping in a Nespresso pod and enjoying a quality shot of espresso with thick crema using the automatic brewing mode. The programmable settings allow customizing brew strength and volume as desired. For the affordable price, it meets expectations as a basic, no-frills espresso maker.

However, a common complaint centers around the temperature of the espresso. Numerous reviews mention the coffee lacks sufficient heat straight from the brewing process. Users report having to microwave their espresso to make it hot enough for enjoyment. Clearly the heating element and thermodyamics of the water flow need re-engineering to produce hotter output temperatures.

Another pain point is quality control. Several users experienced defective units that leaked water all over their counter during the first use out of the box. The malfunction points to substandard manufacturing practices allowing units with damaged internal tubing or improperly sealed valves to get shipped to customers. Closer inspection is required before packaging to prevent dissatisfaction upon delivery.

Additionally, the machine produces significant noise during the 25 second brew cycle. The loud buzzing sound prompted some users to return the product for a quieter alternative. Others considered the noise a temporary nuisance worth tolerating for the quality espresso produced.

In summary, when functioning properly, the Crux 17643 Espresso Capsule Coffee Machine delivers solid performance and value for budget-minded Nespresso fans. However, the flaws around temperature, defects, and noise must be addressed in future models to satisfy a wider range of customers. With some refinements, Crux could have an exceptional and highly recommended home espresso machine.
