Published on Jan. 18, 2024, 4:05 p.m.

Making café-quality espressos and milk-based drinks at home just got easier with the KitchenAid KES6403 semi-automatic espresso machine. Read on to see how this elegantly designed machine can help you brew barista-level beverages in the comfort of your kitchen.

Overview

The KitchenAid KES6403 Semi-Automatic Espresso Machine, characterized by its compact, matte black plastic body, combines style with functionality. Despite its sleek appearance, some users have expressed concerns about the plastic construction, desiring a more durable material like stainless steel. The machine’s fast heat-up thermocoil technology and intuitive controls facilitate a smooth learning curve for beginners. However, it’s worth noting that the machine’s water tank capacity is 1100 ml, which some users find insufficient for high-volume use. Additionally, while the machine boasts easy operation, the quality of espresso can be sensitive to the grind of the beans and the tamping pressure, highlighting the importance of precision in preparation.

Design and Build:

The KitchenAid KES6403 Semi-Automatic Espresso Machine features a sleek, compact design that fits well in any kitchen. While primarily made of plastic, its minimalist aesthetics and matte black finish lend it an understated elegance. The controls are simple and intuitive, with a dial for selecting single or double shots and buttons for espresso and steam functions. Despite the plastic construction, the machine feels sturdy and well-built, and the metal accents on the portafilter and drip tray add a touch of premium quality.

Setup:

The KitchenAid KES6403 Semi-Automatic Espresso Machine can be easily unpacked, assembled, and started within minutes. No complex setup steps required.

Ease of Use:

The front-mounted pulse button and grind setting dial allow easy operation. The grounds bin and hopper can be effortlessly removed for transfer and cleaning.

15-Bar Italian Pump:

The 15-bar Italian pump is the heart of the KES6403, providing the necessary pressure for optimal espresso extraction. This high pressure forces water through the finely-ground coffee, resulting in a rich, flavorful espresso with a thick, velvety crema.

Dual Smart Temperature Sensors:

The dual smart temperature sensors are a standout feature of the KES6403. These sensors actively monitor and regulate the water temperature throughout the brewing process, ensuring optimal extraction and consistent flavor in every shot. This technology sets the KES6403 apart from other machines in its class, as it eliminates temperature fluctuations that can negatively impact espresso quality.

Fast Heating Thermocoil Technology:

Thanks to the thermocoil technology, the KES6403 heats up rapidly, reaching the ideal brewing temperature in under 45 seconds.

58mm Commercial-Grade Portafilter:

The 58mm commercial-grade portafilter is a professional-level feature that allows for even tamping and heat distribution. This ensures that the water evenly saturates the coffee grounds, resulting in a consistent and balanced extraction. The portafilter’s size also makes it compatible with a wide range of accessories and upgrades.

Pre-Infusion Function:

The pre-infusion function is a subtle yet important feature that enhances the flavor of your espresso. Before the full 15-bar pressure is applied, a low-pressure pre-infusion gently wets the coffee grounds. This allows the coffee to bloom, releasing trapped gases and ensuring a more even extraction.

Dual Spout Portafilter:

The dual spout portafilter allows you to brew two espresso shots simultaneously, saving you time and effort when making multiple drinks. This is a convenient feature for households with multiple coffee drinkers or for those who enjoy double shots.

Cup Warmer:

The cup warmer is a thoughtful addition that enhances the overall espresso experience. By preheating your cups, you ensure that your espresso stays hotter for longer, preserving its flavor and aroma. This is especially important for milk-based drinks like cappuccinos and lattes, where the temperature of the cup can significantly impact the final taste.

Commercial-Grade Filter Baskets:

The inclusion of four commercial-grade filter baskets is a testament to KitchenAid’s commitment to quality and versatility. The two single-walled baskets are ideal for experienced baristas who want precise control over their extraction, while the two double-walled baskets are perfect for beginners as they are more forgiving of variations in grind size and tamping pressure.

Dosage Selector:

The dosage selector is a user-friendly feature that allows you to customize the volume of your espresso shots. Whether you prefer a ristretto, a normale, or a lungo, the dosage selector makes it easy to program your desired shot size and achieve consistent results every time.

Auto-Purge Function:

The auto-purge function is a practical feature that helps to maintain the machine’s performance and longevity. After steaming milk, the auto-purge function automatically cools down the thermocoil, preventing overheating and ensuring that the machine is ready for the next espresso extraction.

Versatile Steam Wand:

The steam wand is a powerful tool for creating perfectly textured milk for cappuccinos, lattes, and other milk-based beverages. The wand’s design allows for precise control over the steam flow, making it easy to create microfoam with the desired consistency.

Large 1.4-liter Water Reservoir:

The KES6403 boasts a generous 1.4-liter water reservoir, which means fewer refills and more uninterrupted brewing. The removable reservoir is easy to fill and clean, adding to the machine’s overall convenience.

Noise Level:

The KitchenAid KES6403 Semi-Automatic Espresso Machine operates at a reasonable noise level around 76 db, quieter than many entry-level electric grinders. The grinding noise is smooth, not high-pitched and annoying.

Cleaning:

Brushing out the burrs is easy and other parts are detachable for thorough cleaning.

Durability:

With proper maintenance, the Encore can last 5+ years of regular home use. Baratza provides excellent customer support and a 1-year warranty.

Extra Features:

A handy grounds bin fullness detector alerts when the bin needs emptying.

Safety:

The grinder uses safe, low-voltage DC power. All components meet electrical safety standards.
