How We Choose Coffee Machines, Grinders and Beans

Each buying guide starts with the question a reader actually has, such as a first espresso machine under $500 or a grinder for both espresso and filter. Then we build a shortlist of the models that sell well and are widely available in your country.

What we compare

Espresso machines: boiler type and heat-up time, temperature control (PID), pump and pressure control, steam power, portafilter size, build and serviceability, warranty.
Super-automatics: grinder type, milk system and how easy it is to clean, drink range, noise, running costs.
Grinders: burr type and size, step-less or stepped adjustment, retention, noise, suitability for espresso or filter.
Beans: roast date transparency, origin and process information, certifications, price per cup.

Our sources

Manufacturer specifications and manuals, retailer data, independent long-term owner reports, and for health topics peer-reviewed research, preferably systematic reviews and meta-analyses.

What we never do

Invent test results, measurements or reviews.
Rank a product higher because it pays more.
Hide that we earn commissions.
