A Brief History of Coffee and Espresso

Coffee, one of the world’s most beloved beverages, has a rich history that dates back to the 15th century in Yemen. It quickly spread throughout the Middle East and into Europe, where the cafe culture flourished. The invention of the espresso machine in early 20th century Italy revolutionized coffee culture, introducing the world to concentrated coffee that forms the base of many popular drinks today. Espresso, characterized by its rich flavor and creamy foam known as ‘crema,’ has since become a symbol of Italian craftsmanship and culinary delight.

Brewing: A Professional Espresso Experience

The Kwister CM1687 20 Bar Espresso Coffee Maker is engineered for brewing authentic espresso. Its powerful 20 bar pressure pump ensures optimal extraction, maximizing the release of aromas and flavors from your coffee beans, resulting in a rich, full-bodied espresso. Notably, the CM1687 is not compatible with coffee pods or capsules, a deliberate choice to ensure you experience the purest, most unadulterated flavor from your coffee beans.

Coffee Quality:

The high-end pressure and precision temperature control in the Kwister CM1687 allow it to consistently produce espresso shots that are not only rich in flavor but also visually appealing with a thick, creamy crema on top. This is crucial for espresso lovers who appreciate both taste and aesthetics in their coffee.

Understanding Espresso Machine Features

When choosing an espresso machine, understanding certain key features can significantly impact your buying decision and coffee experience. The Kwister CM1687 boasts a “20 bar pressure” pump, essential for extracting the full flavor from coffee beans, allowing it to achieve a coffee shop level espresso shot. This pressure refers to the force used to push water through the coffee grounds, and higher pressures generally lead to better extraction of flavors.

Furthermore, “PID temperature control” is another sophisticated feature that helps maintain consistent water temperature during the brewing process, ensuring each cup of coffee is brewed to perfection. This is particularly important because minor variations in brewing temperature can lead to noticeable differences in taste.

Another notable feature is the machine’s ability to “customize shot volumes.” This allows users to adjust the amount of espresso extracted, making it easy to cater to personal preferences, whether you like a strong short shot or a milder, larger one.

Mastering Temperature with NTC Technology

Temperature plays a pivotal role in coffee brewing, and the Kwister CM1687’s NTC temperature control system ensures that the machine consistently hits the golden range for espresso (197℉ for brewing and 248℉ for steaming). This precision prevents the under-extraction or burning of coffee, thereby ensuring each cup is as flavorful as one made by a professional barista.

20 Bar Golden Extraction Pressure: Unleashing Coffee’s Essence

The Kwister CM1687 is equipped with a professional 20 bar pressure pump, a key component in crafting exceptional espresso. High-pressure extraction maximizes the release of oils, aromas, and flavor compounds from the coffee beans, resulting in a rich, full-bodied taste. Additionally, the high pressure creates a layer of fine crema, the hallmark of Italian espresso, which not only enhances the coffee’s appearance but also locks in its aroma.

TFT Touch Screen Operation: Smart and Convenient at Your Fingertips

The Kwister CM1687 features a stylish TFT touch screen that is not only easy to use but also waterproof, dustproof, and fingerprint-resistant, making it a breeze to clean. The intuitive touch screen interface allows you to easily select your coffee type, adjust coffee volume, and access other functions.

Customizable Espresso Volume: Personalized to Your Taste

The Kwister CM1687 empowers you to tailor your espresso volume to your liking. You can choose from preset single or double espresso shots or use the manual control button to fine-tune the coffee volume, creating a cup that perfectly matches your taste preferences.

Warming Cup Function: Enhancing Your Coffee Experience

To ensure you enjoy the best possible coffee flavor, the Kwister CM1687 includes a thoughtful cup warming function. Simply place your coffee cups on the warming zone on top of the machine to preheat them, preventing your coffee from cooling down too quickly when poured into a cold cup.
