The Global Spread of Coffee

Coffee, originally cultivated in Ethiopia, began its journey across the globe through trade routes to Yemen and subsequently to the rest of the Middle East. By the 17th century, coffee had made its way to Europe where it quickly became popular. The first coffeehouse in Vienna was established using beans left behind by retreating Turkish invaders, leading to a flourishing cafe culture.

Cultural Impact of Coffee in Europe

In Europe, coffee not only became a social drink that replaced the common breakfast drink of beer but also played a significant role in the intellectual society. Coffeehouses quickly became centers for deep discussions and thinking, dubbed ‘penny universities’ because one could pay a penny for a cup of coffee and engage in stimulating conversations.

The De’Longhi ECAM45055S Eletta Explore is a top-of-the-line fully automatic espresso machine that allows you to brew delicious espresso-based drinks with ease. With advanced features like a built-in burr grinder, intuitive touchscreen interface, dual heating systems for both hot and cold milk frothing, and customizable drink recipes, the De’Longhi ECAM45055S Eletta Explore Fully Automatic Coffee Machine aims to bring café-quality beverages to your home.

How Espresso Machines Work

Espresso machines operate by forcing hot water through finely-ground coffee under high pressure, typically around 9 bars, to produce a rich, concentrated coffee known as espresso. This process, which takes about 25-30 seconds for a single shot, extracts deep flavors and aromas from the coffee grounds, highlighted by the characteristic crema on top—a creamy, frothy layer that forms as a result of the rapid extraction under pressure.

Types of Espresso Machines

There are several types of espresso machines, including manual lever, semi-automatic, and super-automatic. Manual lever machines give users complete control over the extraction process, while semi-automatic machines automate water temperature and pressure. Super-automatic machines take care of all aspects of espresso making, from grinding the beans to frothing the milk.

Specialty Drinks Menu

The Eletta Explore boasts an extensive menu of specialty drinks, catering to diverse tastes and preferences. From classic espresso and americano to more elaborate creations like latte macchiato, flat white, and cortado, this machine offers something for everyone. What’s more, each drink can be customized to your liking, allowing you to adjust parameters such as coffee strength, milk foam amount, and temperature. This level of personalization ensures that you can create the perfect coffee beverage to suit your individual taste.

40+ One-Touch Recipes

The De’Longhi Eletta Explore simplifies the coffee-making process with its extensive selection of over 40 pre-programmed recipes. Whether you crave a classic espresso, a creamy cappuccino, a refreshing iced latte, or even a cold brew, this machine has you covered. With just a touch of a button, you can enjoy your favorite coffee beverages without the hassle of manual adjustments.

User-Friendly Interface

The De’Longhi Eletta Explore’s user interface is a testament to its commitment to user-friendliness. The expansive 3.5-inch color touchscreen display is not only visually appealing but also highly responsive and intuitive. Navigating through the myriad of specialty drink options, adjusting settings, and even creating personalized recipes is a seamless experience. The inclusion of soft-touch buttons with clear icons further simplifies operation, making it accessible even for those who are new to super-automatic espresso machines. Whether you’re a seasoned barista or a casual coffee drinker, the Eletta Explore’s interface ensures that you can effortlessly craft your perfect cup of coffee.


During testing, the De’Longhi ECAM45055S Eletta Explore Fully Automatic Coffee Machine consistently pulled rich, intensely flavored shots of espresso. The microfoam from the steam wands is dense and velvety, allowing you to create latte art quality foam. All of the drinks we tested came out smooth and well-balanced. For an automatic machine, the level of customization and consistent results across different drink types is impressive.

In terms of speed, the De’Longhi ECAM45055S Eletta Explore Fully Automatic Coffee Machine is relatively fast, delivering most drinks in around 1 minute. The initial warm-up takes approximately 1-2 minutes. One downside is the noise level - the grinding and brewing process is quite loud compared to other super automatic machines.

15 Bar Italian Pump

The De’Longhi Eletta Explore is equipped with a 15 bar Italian pump, a crucial component for achieving optimal espresso extraction. This high-pressure pump ensures that water is forced through the coffee grounds at the ideal pressure, resulting in a rich, flavorful espresso with a thick crema layer. The 15 bar pump is a standard feature in many high-quality espresso machines, and its inclusion in the Eletta Explore underscores its commitment to delivering a premium coffee experience.

Intensity and Temperature Adjustment

This coffee machine features adjustable coffee intensity and temperature settings, allowing users to customize the strength and warmth of their coffee to suit personal taste preferences. Whether you prefer a robust or a milder flavor, you can find your perfect cup every time.

Temperature Control

The De’Longhi Eletta Explore features a Thermoblock heating system that ensures optimal water temperature for brewing espresso. The machine also allows you to adjust the coffee temperature to your liking, with five different settings to choose from. This level of control allows you to fine-tune your espresso to achieve the perfect balance of flavor and aroma.

LatteCrema Hot and Cold Systems

One of the standout features of the Eletta Explore is its dual LatteCrema systems. The LatteCrema Hot system froths milk to perfection for your favorite classic espresso beverages like lattes and cappuccinos. Meanwhile, the LatteCrema Cool system creates velvety cold milk foam, ideal for crafting refreshing iced coffee drinks. This versatility allows you to explore a wide range of coffee creations, both hot and cold.

Bean Adapt Technology

The Eletta Explore’s Bean Adapt Technology takes the guesswork out of brewing the perfect cup of coffee. This intelligent feature automatically adjusts the grind and brew settings to suit the specific type of coffee beans you’re using. Whether you prefer light, medium, or dark roast beans, this technology ensures optimal extraction and flavor for every cup.

Ground Coffee Bypass and Versatility

While the Eletta Explore’s electronic grinder is a highlight, it also offers a ground coffee bypass chute for those who prefer pre-ground coffee or want to experiment with decaf options. This feature adds versatility to the machine, accommodating different preferences and needs. However, it’s worth noting that bypass chutes can be prone to clogging, especially with finely ground coffee. Regular cleaning and maintenance of this chute are essential to ensure smooth operation and prevent any interruptions in your coffee-making routine.

Built-In Grinder and Brewing

An integrated conical burr grinder with 13 settings grinds beans fresh for each shot. The Bean Adapt system optimizes the grind and extraction to match the bean variety. During brewing, the ThermoBlock heating system and 15 bar Italian pump ensure optimal temperature and pressure for rich crema and balanced flavor.

Furthermore, advanced espresso machines are often equipped with up to 30 settings for grind size adjustment. This fine level of control allows coffee enthusiasts to adjust the grind size based on personal taste and the type of coffee beans used, perfectly controlling the flavor and texture of the coffee. Especially in machines with dual boiler systems, this precise grinding, combined with consistent temperature control, allows for simultaneous coffee extraction and milk frothing, ensuring that each cup of coffee reaches a professional standard.

Milk Foam and Espresso-Based Drinks

The De’Longhi Eletta Explore’s LatteCrema system opens up a world of possibilities for crafting espresso-based drinks. With its ability to create both hot and cold milk foam, you can easily prepare classic favorites like cappuccinos, lattes, and macchiatos, as well as trendy iced beverages. The difference between these drinks often lies in the ratio of espresso to milk and the type of milk foam used. For instance, a cappuccino typically has equal parts espresso, steamed milk, and milk foam, while a latte has more steamed milk and a thinner layer of foam. Experiment with different combinations to find your perfect espresso drink.


The Eletta Explore contains a 60 oz removable water tank for convenience. The bean hopper holds 8.8 oz of coffee beans. The hot and cold milk carafes each store up to 24 oz of milk.

Programmable On/Off Timer

The programmable on/off timer is a convenient feature that allows you to set the machine to automatically turn on and off at specific times. This means you can wake up to the aroma of freshly brewed coffee or have it ready for you when you return home from work. The timer can be easily programmed through the touchscreen interface, and it adds a layer of convenience to your daily coffee routine.

Additional Features

  • 15 bar Italian pump for optimal espresso extraction
  • Programmable on/off timer
  • Detachable parts are dishwasher safe for easy cleaning
  • Quiet operation around 45 dB

Quiet Operation

Unlike some espresso machines that can be quite noisy, the De’Longhi Eletta Explore operates relatively quietly. This is a significant advantage, especially for those who enjoy their morning coffee in peace or have open-concept living spaces. The quiet operation ensures that the machine doesn’t disrupt your household’s tranquility.

Dishwasher Safe Parts

Cleaning the Eletta Explore is a breeze thanks to its dishwasher-safe parts. The drip tray, grounds container, and other removable components can be easily cleaned in the dishwasher, saving you time and effort. This feature is particularly appealing for those who value convenience and hygiene in their coffee-making routine.

Cleaning and Maintenance

To ensure your De’Longhi Eletta Explore continues to produce delicious coffee and maintain its longevity, regular cleaning and maintenance are essential. The machine features a removable brew group, which should be rinsed daily to prevent coffee residue buildup. The drip tray and grounds container should also be emptied and cleaned regularly. Additionally, the LatteCrema system requires cleaning after each use to prevent milk residue from clogging the nozzles. The Eletta Explore will also prompt you to descale the machine when necessary, a process that helps remove mineral buildup and maintain optimal performance.
