Methodology
How we score machines
Every machine gets the same seven scores, from 0 to 10, and they only mean anything relative to each other. A 9 for build quality means “the best built machine in this catalogue”, not an absolute rating against every espresso machine ever made. When we add machines, we re-score the existing ones so the comparison stays honest.
Where the numbers come from
Each score starts from the specifications — the ones we could verify from the Amazon listing, the manufacturer's own documentation, or a reputable retailer's spec sheet. It is then adjusted, by at most a point, by what the owner reviews consistently say. A machine that looks strong on paper and has a recurring reliability complaint loses that point.
What we will not do
We do not fill in a specification we could not verify. If a value is missing from a spec table on this site it shows an em dash, because a plausible-looking invented number is worse than an obvious gap. We do not write reviews we did not read, and every quoted owner review is quoted from the machine's own Amazon listing.
How we make money
Links to Amazon on this site are affiliate links. If you buy through one, we earn a commission at no extra cost to you. It does not change what we write: the downsides sections on this site are longer than the marketing copy, and the machine with the highest commission is not the one at the top of the guide.
The seven axes
What each score measures
Espresso Quality
Ceiling of what the machine can put in the cup: portafilter size, extraction pressure, temperature stability, grinder quality.
Ease of Use
How fast a beginner gets a good drink. Heat-up time, one-touch recipes, how much technique is required.
Milk & Steam
Quality and convenience of milk texturing: wand power, automation, microfoam capability.
Barista Control
How much of the shot you can actually change: grind, dose, pressure, temperature, mod potential.
Build Quality
Materials, mass, group head construction and expected service life.
Maintenance
How little work it takes to keep it clean and descaled. Higher is less work.
Value
What you get in the cup and in the box relative to what the machine costs.
The overall score
How the seven axes combine
The number on each product card is a weighted mean, not a straight average. A straight average of seven axes pushes every machine to the middle and hides real differences.
| Axis | Weight | Why |
|---|---|---|
| Espresso Quality | ×2.0 | This is a specialty-coffee site. What lands in the cup counts double. |
| Value | ×1.5 | What you get for the money is the reason most people are reading. |
| Milk & Steam | ×1.25 | Most people buying an espresso machine drink milk-based coffee. |
| Build Quality | ×1.25 | A machine you keep for ten years is a different purchase from one you replace. |
| Ease of Use | ×1.0 | Real, but a machine you have to learn is not a machine that is worse. |
| Barista Control | ×1.0 | Matters enormously to some buyers and not at all to others. |
| Maintenance | ×0.75 | Genuinely affects daily life, but rarely decides the purchase. |
