Methodology
How we test coffee gear.
1. Source
We pull candidates from two places: Amazon coffee best sellers (espresso machines, grinders, makers, kettles, scales, and accessories) and a watch list of gear our readers ask about. We never source from sponsored placement, paid catalogs, or influencer lists.
2. Score
Every candidate gets a 0 to 100 score on four axes:
- Brew performance: how it actually brews. Grind consistency, temperature stability, heat-up time, extraction.
- Build: materials, burrs, seals, and what real reviews say after 30+ days of daily use.
- Value: price against comparable gear with the same capability.
- Fit: does the home barista this is built for actually brew better with it?
3. Real-use trial
Anything we are seriously considering, we use for at least 14 days on a real counter. We pull shots, grind beans, and run the kettles ourselves. We document what holds temperature, what retains grounds, what is a pain to clean, and what fails.
4. Numbers, not adjectives
When we describe gear we use numbers wherever we can. "Heats 1L to 96C in 3:40" not "boils fast." "Grind retention under 0.2g" not "low retention." If we cannot back a claim with a number or a source, we cut it from the page.
5. What disqualifies a product
- Fake or AI-generated reviews on the source listing.
- Hyped claims we cannot verify against specs or reviews.
- Listings under 4.5 stars across 90 days of reviews.
- Gear that fails the real-use trial in week 2.
- Anything we would not keep on our own counter.
6. What we disclose
- That our links are affiliate links, on every review.
- That we earn a commission when you buy, at no extra cost to you.
- That the commission never changes a score or a ranking.
- When a product is scored from specs and verified reviews versus hands-on tested on our counter.
