KnowSips Editorial Policy: Research, Sources and Corrections

How KnowSips guides are researched, written, checked, and corrected, and the specific claims this site refuses to make. This is the standard we hold our own pages to, and the one to hold us to.

Bylines and credentials

Articles are published under the KnowSips editorial team. We do not invent authors, and we do not attach titles such as dietitian, nutritionist, physician, food scientist, or barista champion to writing that no such person produced.

Where an article has been checked by a named reviewer with relevant expertise, that reviewer's name appears in the article metadata. Where it has not, no reviewer is listed, and the absence is the honest signal.

This is a deliberate constraint on the site's architecture, not a promise. The reviewer field is empty unless a real person filled it, and the badge only renders when it is filled, so there is no path to displaying a reviewer we do not have.

What we will not claim

KnowSips does not say that a drink treats, prevents, cures, or reduces the risk of any condition. It does not publish weight-loss advice, detox claims, or guidance on medication interactions. It does not tell readers how much caffeine is safe for them, and it gives no advice specific to pregnancy, breastfeeding, children, or any medical condition.

Those are questions for a qualified professional who knows the individual. A drinks reference that answered them would be overreaching, and the fact that such content performs well is not a reason to publish it.

Numbers, ranges, and sources

Where an article states a caffeine figure, a temperature, a ratio, or another measurable fact, it is presented as a range wherever the real-world range is wide, and the source is named at the foot of the page.

Narrowing a range to a single confident number would read better and be less true. A cup of coffee's caffeine depends on the bean, the roast, the grind, the dose, the water, and the time, and a guide that hides that is not helping.

Facts are checked against reference bodies rather than against other blogs. The standing shelf is:

An article that leans on a specific source lists it in its own Sources section. An article without that section is not citing sources it did not use, rather than borrowing this list to look substantiated.

What counts as a source

Not every page that states a number is worth citing. The order of preference is the same every time:

A regulator or a standards body, where a term has a legal or trade definition. What may be called mineral water, what alkalizing does to cocoa, what a decaffeination threshold actually is: these are settled by definition, not by taste.
Published research and reference compositions, for measured values such as caffeine content, extraction behaviour, or how a protein behaves in acid.
Trade and industry bodies, for the vocabulary a field uses about itself and for process descriptions.

What does not count is another article. A number that has been copied between blogs until nobody remembers who measured it is not a source, it is a rumour with a citation style. If a figure cannot be traced back to something that measured it, it does not get printed as a fact.

A manufacturer is a source about its own product and nothing else. A brand page is fine for what is in the packet in front of you; it is not evidence about the category, and it is never evidence about a competitor.

When we cannot check something

Sometimes the honest answer is that nobody has measured it well, or that the figure depends on so many things that a number would mislead. Food and drink writing is full of confident claims of exactly this kind, because admitting uncertainty reads as weakness.

The rule here is to say so. A guide will tell you that a range is wide, that a figure varies by preparation, or that a commonly repeated claim has no good evidence behind it, rather than pick a plausible middle and state it flatly. Leaving a question open is a legitimate answer; inventing a closed one is not.

The same applies to disagreement. Where two credible sources give different figures, the guide reports the spread instead of quietly choosing the one that makes the sentence tidier.

How we name things

Drinks accumulate marketing vocabulary faster than almost anything else on a shelf, and a reference that repeats it becomes an advertisement by accident. So a guide uses the term the trade uses, defines it once in plain words, and then keeps using it.

Words that describe a process are used for that process and no other. Fermented means microbes acted on it. Raw means it was not heated. Cold brew means brewed cold, not chilled after brewing. Where a term is used loosely on packaging, the guide says what it means on the label and what it means technically, because the gap between the two is usually the thing the reader came to find out.

Superlatives and words that promise a feeling — pure, clean, boosting, superfood — are not used to describe a drink. They carry no information, and several of them are close enough to a health claim that using them would breach the line set out above.

Food safety

Some drinks carry genuine handling questions: how long cold brew keeps, what happens to a milk-based drink left out, when fresh juice should be finished.

Where an article covers a topic like that, it carries a caution about that topic. We do not attach one general safety sentence to every page, because a warning that applies to everything tells a reader nothing about the drink in front of them, and it trains people to skip warnings that matter.

Structure follows the question

A guide is shaped by what it is answering. A profile explains what a drink is. A preparation guide gives ratios and a method. A troubleshooting guide works backwards from what went wrong to the one variable worth changing. A comparison puts two things against each other on the attributes that actually separate them.

So a guide is as long as its subject needs and no longer. A section with nothing to say is left out rather than filled, and you will not find the same introduction, benefits and conclusion wrapped around every drink.

You will also only see the parts a guide genuinely has. A drink with no method to give carries no method panel, and a page with nothing to cite carries no sources heading, rather than showing you an empty box with a title over it.

How a guide reads

A wall of unbroken paragraphs is a guide nobody finishes, so every page here is built to be read either straight through or skimmed.

That means the things worth comparing are set out in a table or a labelled scale rather than buried in prose; a method is given as steps you can follow at the counter; the ratios and temperatures you came for are in a panel you can find without reading around it; and the term each section turns on is marked so a quick scan still lands on it.

Photographs are there to show something the words cannot, and any diagram is drawn from the article's own text, so it never shows a step the prose does not mention. Every guide also offers somewhere sensible to go next, because most drink questions lead to another one.

One page, one question

Every guide about a drink lives with that drink. Preparation methods and equipment are explained once, in their own section, so no brewing guide has to stop and re-explain a French press. Head-to-head pages live in one comparison section rather than being duplicated under both subjects.

The result is that each subject has one place to look. You will not find two nearly identical guides saying the same thing in slightly different words, and you will not be sent through a page that exists only to list other pages.

How we choose what to link to

A link inside a guide is there because the sentence around it raises a question the linked page answers. If a paragraph mentions that grind size decides extraction speed, the words naming the grinder link to the guide about grinders. That is the whole test.

Links are not added to spread traffic around, and a guide is not padded with a block of related links at the foot to hit a number. Where nothing genuinely follows from a passage, it carries no link.

Outbound links go to the source itself rather than to a summary of it, so you can check the claim at first hand. They open in a new tab and are marked as external, and we do not link out in exchange for anything. No link on this site has been bought, traded, or requested by the site it points to.

Scope, and why it is narrow

KnowSips covers drinks without alcohol, and nothing else. Wine, beer, spirits, and alcoholic cocktails are outside its scope by design, and are not quietly included under another name. A drink that is genuinely alcohol-free can appear here on its own merits, judged as the drink it is rather than as a substitute for something else.

The narrowness is the point. A reference that covers everything ends up explaining nothing in particular, and the pressure to widen scope almost always comes from what performs rather than from what a reader asked. When we consider a new subject the question is whether we can explain the mechanism behind it properly, not whether people search for it.

That is also why the site has no news, no trends coverage, and no seasonal filler. A guide here is written to be true in five years, and a page that would be embarrassing by then is not worth publishing now.

What a search engine is told about a page

Alongside the words you read, a page carries a short machine-readable summary of itself. Ours only ever describes what is visibly on the page.

Recipe data is attached only to articles that genuinely give a drink you make and drink, with real ingredients, an ordered method, and a yield. An article about how a drink tastes, or how a piece of equipment works, is not marked up as a recipe just because the subject happens to be drinkable. Question-and-answer data is attached only where the questions and answers are on the page for a reader to see.

There is no rating or review data anywhere on this site, because KnowSips does not rate or review products.

Images

Most editorial images are created with an image-generation model from a description written for that page. An editor checks the finished image against the intended subject and rejects it when the drink, equipment, ingredient, or setting is wrong.

Every page's image is unique to it; we do not reuse one image across several guides. Subjects are generic drinks, equipment, and ingredients, never a real named place or a real person, and alt text describes what is actually shown.

What gets checked before a guide goes up

A standard that exists only as a paragraph on a page like this one erodes quietly. Each of the promises above is checked on the finished page rather than trusted:

The figures: Every temperature, ratio, and caffeine number is read back against the source it came from, and a range that was narrowed is put back.
The links: Every link is followed. One that has gone dead, or that promises a page it does not lead to, is fixed rather than left for you to find.
The pictures: Every photograph loads, belongs to the guide it sits in, and carries a description of what is actually in it.
On your screen: Every page is read at phone width before it is published, because a ratio you cannot see without scrolling sideways is no use at the kettle.

A guide that does not come through that is repaired before it goes up, not published with a note about it.

Updates and corrections

Guides carry a published date, and an updated date once revised. When we find a factual error we change the article rather than leaving it and noting the correction somewhere else.

Corrections can be sent through the contact page and are the most useful message we get. Tell us the page and what it should say.

Independence

KnowSips does not sell products, run affiliate links, or accept payment for coverage or placement. No brand has a say in what appears here, and no page has a commercial reason to prefer one product over another.
