Espresso: A Rich History

Espresso originated in Italy in the early 20th century and is a coffee brewing method that uses high-pressure hot water to quickly extract coffee powder. Espresso means “fast” in Italian, which also reflects the characteristics of its production process. Espresso has a strong taste and unique oil (Crema), and is the basis of many classic coffee drinks, such as cappuccino and latte.

Coffee Quality - Rich, Bold Espresso

Equipped with a 20 bar Italian pump and 1350W heating system, the amzchef U-LL-1666SV 20 Bar Espresso Machine consistently delivers rich espresso with thick golden crema and robust flavor. Water reaches optimal brewing temperatures fast for scrumptious espresso worthy of a high-end cafe.

Coffee Grind Size: Unlocking Different Flavors

In addition to choosing the type of coffee beans, the grind size of the coffee beans will also greatly affect the final coffee flavor. The finer the grind, the larger the contact area between the coffee powder and water, and the more flavor substances are extracted, resulting in a richer coffee taste, but may be accompanied by bitterness. The coarser the grind, the less flavor substances are extracted, and the lighter the coffee taste. The amzchef U-LL-1666SV espresso machine is compatible with coffee grounds of different grinds, so you can adjust it according to your taste preferences to make the most suitable coffee for you.

Brewing - Flexible Customization

The amzchef U-LL-1666SV 20 Bar Espresso Machine can brew using ground coffee or convenient ESE pods with the included filters. Customize single or double shots at the ideal temperature and volume. Its versatility suits all types of coffee drinks from short ristrettos to long lattes.

Pressure - Commercial-Grade Extraction

With 20 bars of pressure, the amzchef U-LL-1666SV 20 Bar Espresso Machine extracts maximum flavor oils and aromatics from ground coffee, producing espresso comparable to high-end machines costing twice as much.

Pressure and Flavor: The Gold Standard of 20 Bar

20 Bar pressure is the gold standard for Italian espresso. When hot water passes through the coffee powder under such high pressure, the oils, aromatic substances and flavor compounds in the coffee beans are fully extracted. These substances give Italian espresso its unique mellow taste, rich oil and strong aroma. In contrast, low-pressure extracted coffee may taste bland and lack layering. The amzchef U-LL-1666SV espresso machine is equipped with a 20 Bar pressure system to easily make professional Italian espresso at home.

Importance of 20 Bar Pressure in Espresso Extraction

The 20 bar pressure system is a key feature of the amzchef U-LL-1666SV Espresso Machine, as it plays a crucial role in espresso extraction. This high-pressure system forces hot water through finely-ground coffee beans, resulting in a rich, concentrated espresso shot. It ensures the extraction of maximum flavor, aroma, and essential oils from the coffee, which are vital for creating a well-rounded espresso. This section explores how the 20 bar pressure contributes to the superior quality of espresso compared to lower pressure systems.

Temperature Control - Fast, Consistent Heating

Rapid heating technology achieves optimal 195-205°F temperatures in seconds while PID temperature control maintains stability for smooth, balanced flavor.

Temperature and Extraction: The Key to Flavor

The temperature of coffee extraction directly affects the flavor of the coffee. Too high a temperature will make the coffee bitter, while too low a temperature will not be able to fully extract the flavor substances of the coffee. The ideal extraction temperature for Italian espresso is between 90-96°C. The amzchef U-LL-1666SV espresso machine adopts rapid heating technology and PID temperature control to ensure that the water temperature is always kept within the optimal extraction range, so that every cup of coffee can present the best flavor.

Innovation - Café-Worthy Performance

Unlike most consumer models, the amzchef U-LL-1666SV 20 Bar Espresso Machine mimics commercial machine features like 20 bar pressure, rapid heating, and microfoam frothing for a superior at-home espresso experience.

Reservoir - 1.3 Liter Capacity

The removable 1.3 liter water tank allows brewing 3-4 drinks before needing a refill. Its integrated filter improves water quality for a purer coffee taste.

Milk Frothing - Velvety Microfoam

The adjustable steam wand expertly froths milk into light, creamy microfoam for making flawless cappuccinos and lattes. Its simple knob dial lets you fine-tune foam texture and temperature.

Creating the Perfect Milk Foam: Tips and Tricks

With the steam wand of the amzchef U-LL-1666SV espresso machine, you can easily create delicate milk foam. First, refrigerate the milk to 2-5°C and pour it into the milk jug to 1/3. Insert the steam wand about 1 cm below the surface of the milk and open the steam valve. As steam is injected, the milk in the jug will begin to swirl, creating lots of bubbles. At this time, slowly lower the milk jug so that the steam wand is always kept below the surface of the milk until the milk reaches the desired temperature and texture.

Impact of Milk Types on Frothing

The type of milk used can significantly affect the texture and quality of the froth produced by the espresso machine’s steam wand. Full-fat milk tends to create richer and creamier froth, while low-fat or non-dairy alternatives like almond or soy milk may produce lighter froth with varying stability. This section will guide you on choosing the right milk type for your preferred coffee beverages and how each type impacts the frothing outcome.
