How to choose kitchen knives: the specifications worth comparing
Marketing language around kitchen knives is dense with vague superlatives. A short list of measurable specifications tells you far more than the branding.
Best coffee machines
Temperature stability, pressure at the basket, maintenance burden and the true cost per cup.
Research in progressPublished rankings appear only after testing is complete.

Our picks
Nothing published until testing is finished.
Most coffee machine specifications quote pump pressure, which is close to meaningless — what matters is pressure at the basket and how stable the brew temperature is shot to shot. We measure both, and we calculate cost per cup including descaling, filters and pods where relevant.
No picks published yet
This guide is in the research stage. We will not list a "best" product before the testing round behind it is complete — an unranked page is more useful than a ranked guess. When picks go live, each one will state what we tested, how long for, what it is good at, and who should buy something else instead.
What we score, and why
Written down before any product is considered.
- Brew temperature stability across consecutive extractions
- Actual pressure at the basket, not pump rating
- Steam power and milk texturing capability
- Cost per cup including consumables
- Descaling and maintenance frequency
- Parts availability and serviceability
How we will decide
- 01
Criteria before candidates
We write down what would make a product the right pick — and how each criterion is measured — before we look at what is on sale.
- 02
Documented specifications only
Anything we state about a product comes from our own testing or from the manufacturer's published documentation, linked on the page.
- 03
Real-world testing
Where a category can be tested, we test it over weeks rather than an unboxing session, and we publish the conditions we tested under.
- 04
Pricing checked, not quoted
We do not print a price we have not verified, and we do not treat an RRP as evidence of a discount.
- 05
Commercial relationships disclosed
Affiliate links, if present, are labelled on the page. No partner can buy a placement, a rank or a verdict.
The full process is documented in our review methodology and testing process.

Best before, use by, sell by: what food date labels actually mean
The date printed on a package is not one universal signal. Regulators define several different types, and mixing them up causes a meaningful share of avoidable food waste.
