About Coffee Studies

Coffee Studies is an evidence-led coffee education project. We cover caffeine, brewing science, beans and origins, instant and decaf coffee, coffee alternatives, and functional coffee — in plain English, with citations you can check.

Who publishes this site

Coffee Studies is published by Nature Lion Inc., a Canadian company that also makes Shyne Coffee, a freeze-dried instant mushroom coffee. We say this up front because credibility starts with transparency: this site exists both to be genuinely useful and to support a coffee business we care about.

What that does not change: the editorial content here is written to stand on its own. Sponsored placements for Shyne are always labelled, never woven into the editorial text, and never make health claims.

How we handle evidence

• Factual claims are cited against our source library of studies, agency guidance, and official datasets, graded by evidence strength.
• We use cautious language — “associated with,” “may,” “research suggests” — and we distinguish observational research from causal evidence.
• Health-related articles carry a disclaimer: our content is educational, not medical advice.
• Articles are written under the collective byline Coffee Studies Editorial and reviewed before publication.

How this site makes money

Three ways, and you should know all three before you trust anything here.

• Our publisher sells coffee. Coffee Studies is published by Nature Lion Inc., which makes Shyne Coffee. The sponsor slots on this site are Shyne’s, and they are labelled as sponsor content wherever they appear. Shyne never appears inside an article as a recommendation, and no article’s conclusion is written to suit it.
• Some equipment links are affiliate links. Where an article names a specific piece of gear, the link to it is an Amazon affiliate link and we earn a commission if you buy. As an Amazon Associate we earn from qualifying purchases. The disclosure appears again directly above every product block, before you click anything.
• Nobody pays to be named. No manufacturer has paid for placement here, sent us a free unit, or seen an article before it published. We name the thing the mechanism calls for, and we say what it costs on both the US and Canadian storefronts along with the date we last checked.

We used to say this site carried no affiliate links at all. That stopped being true, so we changed the page rather than the practice: hiding it would have been the dishonest option, and it would have contradicted the one thing we ask readers to do everywhere else, which is to check who benefits from a claim.

What we are not

We are not a university, a medical institution, or a certified research body — and we do not pretend to be. We are not a gear-review site either: we do not run lab tests, we do not rank products against each other, and we do not publish “best coffee maker” roundups. Where equipment appears, it is because an article explains a mechanism that requires a particular kind of tool, and it names an example that meets the specification.

Corrections

If you find an error or a citation that does not support a claim, we want to know. Contact us at hello@coffeestudies.com and we will review and correct promptly.
