Understanding this context will illuminate why the Apex stands out, particularly for beginners in the home barista scene.

 MiiCoffee Apex Espresso Machine

Design and Materials

Enclosed in a brushed stainless steel body, the MiiCoffee Apex Espresso Machine has a compact footprint of 27.9 x 22.9 x 38.1 cm and weighs only 8.6 kg. The sleek exterior gives it the stylish look of a commercial machine.

The MiiCoffee Apex Espresso Machine’s design combines functionality with aesthetic appeal. The brushed stainless steel exterior not only provides a modern and stylish look but also ensures durability and ease of cleaning. The machine’s compact design is perfect for home use, fitting seamlessly into various kitchen styles without occupying excessive space.

Attention to detail is evident in the machine’s ergonomic portafilter handle and intuitive control panel, which enhance user experience. The robust construction and choice of high-quality materials reflect MiiCoffee’s commitment to producing durable and reliable espresso machines.

Ease of Use

As a semi-automatic machine, the MiiCoffee Apex Espresso Machine allows you to pull espresso shots with a simple tap of the brew button. Just load ground coffee into the portafilter, tamp, lock it into the group head, place cups under, and hit brew.

Brew Types and Capsule Compatibility

The MiiCoffee Apex Espresso Machine uses ground coffee in its 58mm commercial portafilter basket. It is not designed for Nespresso or other coffee capsules. This machine is focused purely on making high-quality espresso using freshly ground beans.

Coffee Types

With its 9 bars of pressure and PID temperature control, the MiiCoffee Apex Espresso Machine can brew a variety of coffee drinks. It excels at crafting rich, aromatic espresso, the foundation of many popular beverages. From the classic espresso shot to the longer, more diluted lungo, the Apex delivers a consistent and flavorful extraction. The machine’s steaming capabilities further expand your options, allowing you to create creamy lattes, cappuccinos, and other milk-based espresso drinks. Whether you prefer a bold, concentrated espresso or a frothy, comforting latte, the Apex has you covered.

Coffee Quality

Users report the MiiCoffee Apex Espresso Machine pulls shots with a thick, velvety crema and complex flavors reflecting the origin and roast of the beans. The precision PID temperature control ensures water is heated to the optimal temperature for extraction, preventing under- or over-extraction that can lead to bitter or sour flavors. The low-pressure pre-infusion further optimizes extraction for cafe-quality taste.

To optimize your coffee experience, you can adjust the PID settings to slightly lower temperatures when brewing delicate, light roast beans to enhance their floral notes. Conversely, for darker roasts, a slightly higher temperature setting can help in extracting the rich, chocolatey flavors more effectively. Experimenting with these settings, along with the adjustable pre-infusion time, allows users to achieve a personalized coffee experience that suits their taste preference perfectly.

How Semi-Automatic Espresso Machines Work

Semi-automatic espresso machines, like the MiiCoffee Apex, strike a balance between manual control and automatic functionality. Users grind the coffee, tamp it, and press a button to start the extraction process. The machine controls the water temperature and pressure, ensuring consistent espresso shots. Understanding this balance is crucial for appreciating the control and convenience offered by the Apex.

Technological Specifications and Features

The MiiCoffee Apex Espresso Machine stands out with its 1450W power output and 550ml stainless steel boiler, ensuring quick heating and consistent espresso brewing. The machine’s dimensions of 11”D x 9”W x 15”H make it an ideal choice for kitchen countertops without sacrificing valuable space.

Key features include a PID (Proportional-Integral-Derivative) temperature controller. This system allows users to fine-tune the brewing temperature, crucial for extracting the perfect espresso. Unlike traditional systems that might only toggle the boiler on or off, the PID system continuously calculates the exact power level needed to maintain the desired temperature. This precision prevents temperature swings that can adversely affect the taste of espresso by ensuring the water is exactly right for extracting the fullest flavor from the coffee grounds.

The machine’s ability to reach 9 bars of extraction pressure, the industry standard for espresso, is facilitated by an Italian-made vibratory pump, known for its reliability and longevity.

Furthermore, the Apex offers programmable pre-infusion, enhancing the espresso’s flavor by allowing the coffee to bloom before full extraction. This feature, combined with the machine’s precise temperature control, enables users to achieve a barista-level espresso at home.

In addition to its brewing capabilities, the machine boasts a separate thermo-block for steam production, enabling users to froth milk to a creamy consistency for lattes and cappuccinos. The inclusion of a commercial-grade 58mm portafilter ensures that users experience a professional brewing process.

Italian-Made Vibratory Pump

The heart of the Apex is an Italian-made vibratory pump, renowned for its reliability and performance. This pump delivers a consistent 9 bars of pressure, the ideal pressure for espresso extraction. The result is a rich, flavorful espresso with a thick, velvety crema.

Pressure Gauge

The MiiCoffee Apex features a pressure gauge that displays real-time brewing pressure. This allows users to monitor the extraction process and ensure that the espresso is being brewed at the optimal pressure. The pressure gauge provides valuable feedback for dialing in the perfect shot, helping users achieve consistent and delicious results.

Thermo-Block Heating System

The Apex utilizes a thermo-block heating system for steaming milk. This dedicated system allows for quick and efficient steam production, enabling users to create perfectly textured milk for lattes and cappuccinos. The thermo-block system ensures consistent steam power, making it easy to achieve professional-quality microfoam.

PID Temperature Control

The MiiCoffee Apex is equipped with a PID controller, allowing users to precisely adjust and maintain the brewing temperature. This ensures optimal extraction of flavors from the coffee grounds, resulting in a more consistent and delicious espresso. The PID controller also doubles as a shot timer, providing valuable feedback during the brewing process.

550ml Stainless Steel Boiler

The Apex features a 550ml stainless steel boiler, providing ample capacity for brewing multiple espresso shots in quick succession. The stainless steel construction ensures durability and longevity, while the boiler’s size allows for consistent temperature stability during brewing.

Pre-infusion Function

The Apex includes a pre-infusion function, which gently wets the coffee grounds before extraction. This pre-infusion process helps to evenly saturate the coffee bed, resulting in a more uniform extraction and a more flavorful espresso. The Apex allows users to adjust the pre-infusion time, giving them more control over the brewing process and allowing them to experiment with different flavor profiles.

58mm Commercial Portafilter

The MiiCoffee Apex comes equipped with a 58mm commercial-grade portafilter. This portafilter is made from stainless steel and is designed to withstand the rigors of daily use. The 58mm size is the industry standard for espresso machines, ensuring compatibility with a wide range of accessories and upgrades. The commercial-grade portafilter also contributes to the overall quality and consistency of the espresso brewing process.

Milk Frothing

The MiiCoffee Apex Espresso Machine features a single thermo-block steam wand for steaming and frothing milk. It can produce silky, microfoam milk texture when the steam power is properly controlled. However, the frothing capacity is relatively limited compared to larger dual-boiler machines.

Water Tank Capacity

It has a 1.7 liter removable water tank. The large capacity allows making multiple drinks before needing a refill. Just add water every few days for daily home use.

Cup Warming Tray

The MiiCoffee Apex Espresso Machine features a cup warming tray on top, allowing users to preheat their cups before brewing. This helps to maintain the temperature of the espresso, ensuring a more enjoyable drinking experience. The cup warming tray is a convenient feature that adds a touch of professionalism to the home brewing setup.

Three-Way Solenoid Valve

The Apex is equipped with a three-way solenoid valve, a feature often found in higher-end espresso machines. This valve releases pressure from the portafilter after brewing, resulting in a dry coffee puck that is easy to discard. The three-way solenoid valve also helps to prevent dripping and ensures a cleaner brewing process.

5-Foot Power Cord

The MiiCoffee Apex Espresso Machine comes with a generous 5-foot power cord, providing flexibility in terms of placement in your kitchen. This allows users to position the machine in a convenient location without being restricted by the length of the power cord.


The machine produces some noise during operation, primarily from the pump and the steam wand. The pump noise is most noticeable during brewing, as it generates the pressure required for extraction. The steam wand produces a hissing sound when in use, which is typical for espresso machines. However, reviewers generally find the Apex to be quieter than some other models in its class.


With a stainless steel body, commercial-grade wiring, and UL certification, the MiiCoffee Apex Espresso Machine meets North American electrical safety standards. The UL mark indicates that the product has been tested and evaluated for potential hazards such as electrical shock and fire. This certification provides an added layer of assurance for users, ensuring that the machine is safe to use in their homes.
