How the overall 0.0 – 10.0 score is determined for every product in Coffee Machines.
Multi-parameter evaluation based on objective hardware specifications, benchmark measurements, energy efficiency, capacity, and materials.
Every independent review of the model gets a grade from 1 to 10: the reviewer's own score when the page shows one (stars, x/10, test grade), otherwise a grade from the written verdict on a fixed scale.
The technical score (95–100% of the overall score) is split into 4 areas. Each area has its own weight and its own set of specs.
Covers power, water tank size, pump pressure, heat-up time, heating system and boilers, the built-in grinder and its settings, mains water connection and noise.
When it matters: Most important for making several coffees in a row, grinding beans fresh for every cup and having the machine ready quickly in the morning.
10 specs explainedCovers the machine type, the coffee it takes (ground, beans, ESE pods, capsules), portafilter and tamper, milk frothing, one-touch drink programs, hot water and temperature control.
When it matters: Most important when choosing between espresso by hand and one-touch drinks, and for anyone who drinks cappuccino, latte or iced coffee.
23 specs explainedCovers water level and drip tray alerts, water filter, descaling and cleaning programs, safety shut-off, sleep mode, two-cup brewing, cup warmer and app or voice control.
When it matters: Most important for easy daily care with hard water, for households that make two cups at once and for a machine that saves power on its own.
14 specs explainedCovers built-in or freestanding, colour and retro look, housing and drip tray materials, display and touch screen, water tank access, cup clearance, portafilter size, dimensions, weight and cable length.
When it matters: Most important when the machine must fit under kitchen cabinets or into a unit, take tall glasses or match the look of the kitchen.
14 specs explainedWhat each spec we compare means, when it matters to you, and how much it counts in the score. Product pages show the same explanations when you hover or tap a spec.
What it is: The electrical heating and pumping power consumption of the espresso machine in watts.
When it matters: Higher wattage enables faster initial warmup, quicker steam recovery between drinks, and more stable brewing temperatures during back-to-back cups.
What it is: The maximum rated pressure produced by the internal water pump, typically 15 to 20 bar on domestic vibration pumps.
When it matters: Ensures the pump overcomes resistance through finely ground coffee to deliver the optimal 9 bar extraction pressure required for thick, hazelnut crema.
What it is: The time in seconds required for the heating system to reach initial brewing temperature from a cold start.
When it matters: A fast warmup (15–40 seconds with modern thermoblocks) means you can brew your morning espresso immediately without waiting.
What it is: The maximum mass of whole roasted coffee beans in grams that the hopper can hold under an aroma-preserving lid.
When it matters: A generous hopper (250g–300g) holds an entire standard bag of beans at once, reducing frequent refilling in households with multiple coffee drinkers.
What it is: The usable volume of the removable clean water reservoir in litres.
When it matters: Determines how many espressos, Americanos, or steamed milk drinks you can prepare before needing to refill the water tank.
What it is: The number of distinct grind-fineness adjustment steps available on the integrated coffee grinder.

The 10 specs that move the technical score the most. Impact = share within its area × the area's weight.
Which reviews count and how their grades become the review score.
Only independent reviews of that exact model: test sites, magazines and video reviewers in 6 languages. Shop pages, brand-paid content, pure list pages and pages without a verdict are left out.
Since version 2.0, star ratings from online shops no longer count towards the overall score in this category, and graded video reviews count next to written tests. Expert reviews compare models side by side and are harder to game than shop ratings.
The review share is set per category by how many weighted reviews a typical model has: when half the models have 8+, reviews count 35%; 7+ 30%; 6+ 25%; 5+ 20%; 4+ 15%; 3+ 10%; 2+ 5%. With fewer, reviews are shown but not scored. Every model in the category gets the same split.
A model with few reviews should not win or lose on one or two grades. Each missing review counts as 7/10, an average grade, so a model moves far from 7 only when several independent reviews agree. Our own grades of reviews without a printed score are aligned to the level of printed scores (blind test: +1). We grade the most trusted reviews first and keep adding the rest; every graded review counts.
