The Hong Kong Consumer Council has released its latest test report on 10 espresso machine models, revealing that while most units performed admirably, several popular brands showed concerning water temperature instability during continuous brewing. The comprehensive evaluation, conducted in collaboration with the International Consumer Research and Testing organisation (ICRT), assessed machines from De’Longhi, Philips, Xiaomi, and other leading brands across both fully automatic and semi-automatic categories.
The Testing Methodology
Laboratory technicians evaluated each machine against European standard EN 60661, with professional coffee tasters conducting sensory assessments. The four core testing criteria covered coffee-making performance, including preheating time, brewing speed, coffee temperature, residual drips, dual-cup consistency, milk frothing quality, and cappuccino preparation ease. Additional assessments examined user convenience and customisation features, operational noise levels, and energy efficiency.
Overall Performance Scores
Most samples achieved satisfactory to good ratings, scoring between 3.5 and 4 out of a possible 5 points. However, the report flagged concerning issues with certain models. Philips and Xiaomi units exhibited unstable coffee temperatures during sequential brewing sessions, a significant drawback for consumers who prioritise flavour consistency across multiple cups.
The Core Difference: Fully Automatic vs. Semi-Automatic
Understanding the distinction between machine types remains crucial for informed purchasing decisions.
Fully automatic machines suit those seeking convenience. Users simply add coffee beans and water, press a button, and the unit handles grinding, dosing, tamping, and extraction automatically. Most models offer multiple beverage options like cappuccino and latte, along with adjustable coffee strength, water temperature, and grind settings. The trade-off: more complex internal mechanisms require meticulous cleaning and descaling, and prices generally run higher.
Semi-automatic machines appeal to enthusiasts who enjoy hands-on involvement. These units split into two subcategories:
- Models with built-in grinders allow immediate bean grinding while requiring users to manually tamp and control extraction timing, offering greater creative freedom.
- Models without grinders feature simpler, more compact designs. Users need pre-ground coffee or a separate grinder. Since dose and tamp pressure depend entirely on the user, flavour outcomes vary considerably, adding an element of experimentation.

Practical Takeaways for Consumers
For those prioritising consistent espresso quality across multiple servings, models with stable temperature performance should take precedence over brand recognition alone. Buyers should consider their daily usage patterns: frequent multiple-cup brewing demands machines that maintain thermal stability, while occasional single-cup users may find temperature fluctuations less impactful.
The full Consumer Council report, published in Choice magazine issue 597, provides detailed individual model ratings and expert recommendations. Prices may vary, so shoppers should verify current pricing with retailers before making final decisions. Understanding these test results empowers consumers to select a machine that aligns with both their coffee preferences and lifestyle requirements.
