How Perfect Brew Picks reviews are written

Every review on this site is written from the manufacturer’s published specifications and documentation for that model. This page says exactly what that means, and where it falls short.

The source

A review starts from the product’s specification sheet, its listing, and where available the manufacturer’s manual. The figures a review quotes — pump pressure and boiler type on an espresso machine, wattage, reservoir or carafe capacity, brew temperature where stated, burr type and diameter and the number of grind settings on a grinder, pod system on a single-serve machine, cup size on a moka pot or press, temperature presets and hold time on a kettle, materials, and the width, height and depth — are the manufacturer’s figures, restated. We do not measure any of them.

Where a manufacturer publishes a figure under a stated condition, the condition matters. A “20 bar” pump is a maximum the pump can produce, not the 9 bar the coffee is extracted at; a “12-cup” carafe is twelve five-ounce cups. A review should say what the figure describes, not just repeat it.

What a review does with the figures

A specification is only useful against a question. A single boiler is fine for someone who drinks espresso and a nuisance for someone who steams milk every morning; a 12-cup drip machine is right for a household and wrong for one person who wants a fresh cup; a 40 mm burr set is plenty for filter coffee and marginal for espresso. So each review reads the model’s figures against the coffee its category makes — milk drinks for an espresso machine, a pot for the office for a drip machine, a single cup in a hurry for a pod brewer — and says who the numbers suit and who they do not.

Pressure figures are treated with particular care, because they are the most misleading number in the category. Espresso is extracted at around 9 bar; a machine advertising 15 or 20 bar has a pump that can reach that and an over-pressure valve that stops it. A review says what the pump is and does not rank machines by the number on the box.

What a review does not do

  • No hands-on brew withing. No shot pulled, no grind dialled in, no brew timed, no temperature measured, no coffee tasted. Any sentence in a review that reads like an observation is an inference from the published specification, and where that is not clear the sentence is wrong and should be corrected.
  • No ratings or review counts. We do not publish star ratings, owner review counts, or anything derived from customer reviews.
  • No prices. A price captured when a review was written is wrong by the time you read it.
  • No defaults. Where a manufacturer does not publish a figure, the review does not fill the gap with a plausible one.

Categories

Each review is filed under one of six categories: espresso machines, coffee grinders, drip coffee makers, single-serve & pod brewers, french press, pour-over & moka and electric kettles brewing appliances. The category is decided by how the machine makes coffee, not by what the listing calls it — a machine with a pump and a portafilter is an espresso machine whether or not it also drips, a stovetop moka pot is a manual brewer whether or not it says espresso, and a machine that takes only capsules is a single-serve brewer whatever pressure it claims.

The 2026 clean-up

Until September 2026 the site also carried reviews of coffee pods and capsules, teas and teabags, descaler, storage canisters and tea tins, teapots, a pepper mill and a grain mill. On 2026-09-12 we classified all 588 pages by the product named in their title and removed 44 from search indexing. The rule was simple: if the product is not a coffee maker, the review is not part of this site’s subject. The 543 pages that remain are brewing appliances, and the categories above contain nothing else.

The removed reviews were not deleted. They still resolve for anyone who has a link to one, and they still carry the same disclosure and the same affiliate links. They are simply no longer offered to search engines.

Where this method fails

It inherits every weakness of its source. If a manufacturer quotes a pump maximum as if it were the brewing pressure, the review can explain the difference but cannot supply the true figure. If a listing omits brew temperature — and most drip machines do — so does that part of the review.

It also cannot tell you anything a specification does not encode: how stable a boiler’s temperature is shot to shot, how much coffee a grinder retains between doses, how a kettle’s lid seals, whether a carafe drips when it pours, or how a machine tastes against another. Those are the things brewing with it would tell you, and this site does not do that.

Accountability

Reviews are published under the editorial name Lucas Bennett, which is disclosed as a pen name. The method above is the point of accountability: if a review departs from it, the review is wrong and should be corrected, and there is no biography to hide behind.
