About this site

Who runs this

Coffee Info is an information site run solo by a student who loves coffee. It is not a team or a company — one person handles the planning, writing, design and development.

It grew out of simple curiosity — “why is the coffee at a café so good?”, “why does the same bean taste completely different depending on how it is brewed?” — and the notes I kept while researching origins, varieties, brewing and market prices became the backbone of this site.

I write while practising cupping and pour-over and tasting 30+ beans a month. There are no sponsored articles; recommendations are based on hands-on experience. As a student I have no dedicated editorial team or proofreader, so I actively welcome and act on corrections from readers who spot mistakes.

Scale

Launched in 2025, the site currently offers data and articles at this scale:

All origin data and flavor records are managed centrally as the site’s dataset (origins.json); the comparison tools, the quiz and the map all read from this single source. To keep data consistent and current, everything is structured and propagated to every page rather than edited piecemeal by hand.

What this site aims for

The goal is a knowledge hub — open to both beginners and enthusiasts — that turns coffee from “just something you buy and drink” into “a cup that travels the world.”

• Know the origin: for 35 coffee-growing countries, see geography, varieties, flavor, harvest calendar and market price on a single page
• Learn to brew: make the “invisible” variables — golden ratio, water temperature, grind size — visible with calculators and recipes
• Record your experience: save tastings, inventory, brew logs and blend designs on your device to build a coffee diary that is yours alone
• Read deeply: editorial pieces that satisfy curiosity — “the drink-by window after roast date”, “why Geisha is so expensive”, and more

Editorial principles

• No hype: avoid sensational phrasing like “magic cup” or “fail-proof”; write claims together with the evidence
• No pushing: present “here are the options” rather than “this is the right answer”, respecting that final preferences differ from reader to reader
• Transparency: affiliate links are clearly marked “PR”; the line between advertising and editorial is never blurred
• Keep facts current: outdated info and errors are fixed promptly; articles show a publish date, and an update date is appended at the end when content changes
• Privacy first: your tasting records and inventory are stored only on your device (localStorage / IndexedDB); nothing is sent to a server
• Health information: figures like caffeine content and intake limits use official sources (EFSA, FDA) as primary references, and are explicitly not a substitute for medical advice

How we pick gear & services

The comparison and ranking pages (drippers / grinders / bean-to-cup machines / kettles / espresso machines / subscriptions, etc.) are built to the following standards.

• Basis for selection: choices combine my own hands-on use with manufacturer specs, reference books and well-regarded field evaluations.
• How ranks are set: rankings are based on “fit for the use case” and “ease of choosing as a first purchase.” Ranks are never changed by whether or how much affiliate revenue is involved.
• Price notation: prices are shown as ranges (rough guides); always confirm street prices and stock on each retailer’s site.
• How links are built: to resist discontinuations and stockouts, most links are search links; only stable staples link directly to a specific product.
• Updates: each page states when it was last updated and is revised when line-ups or price bands change. Corrections are welcome.

Sources

This site uses published data from the following public and specialist bodies as primary sources:

• ICO(International Coffee Organization): production and export statistics by origin
• SCA(Specialty Coffee Association): flavor wheel and cupping protocol
• WCR(World Coffee Research): variety database and the modern flavor wheel
• ICE futures: Arabica and Robusta futures prices (fetched in real time)
• FRED(Federal Reserve Bank of St. Louis): commodity price data via the IMF
• EFSA / FDA: official recommended caffeine intake levels
• Wikimedia Commons: origin photos (with credit lines)

Articles are written by combining those primary sources with books (e.g. The World Atlas of Coffee, Introduction to Coffee Science), trade magazines, SCA certification materials, and my own cupping and brewing experience. Where a source can be identified, it is cited.

Recent articles (selection)

Roughly 3–6 articles a month. What actually gets published is the real measure of editorial quality.

How we update

Origin data is added or updated once or twice a month; articles at least once a week. Price data updates automatically every trading day (US market basis).

For research and statistics cited in articles, the most recent published figures (within 1–3 years where possible) are used. When older data is cited, the reason (historical value, time-series comparison, etc.) is explained in the text.

When an error is found, the correction is noted at the end of the article as “Updated: YYYY-MM-DD.” The same applies when underlying price or statistical data is updated.

Monetization

As a solo project, the site is monetized in the following ways to cover server and domain costs:

• Affiliate links (Amazon, Rakuten, Yahoo! Shopping, A8.net, ValueCommerce, etc.)
• Advertising via Google AdSense (planned)

Every affiliate link is marked “PR.” So readers never lose out, the order is strictly “I recommend it because I actually used it and thought it was good,” not “I recommend it because there is an affiliate payout.”

I also do not currently write articles in exchange for money or goods from roasters or gear makers. Should such a relationship ever arise, it will be stated clearly at the top of the relevant article. For details, see the Privacy Policy.

Contact & corrections

For article errors, requests, collaborations or anything else, please get in touch via:

• The settings icon at the top right opens a “Contact” form to message me directly
• Correction requests: if there is a factual error or an inaccurate source, please point it out together with the evidence. Errors in published figures or statistics are fixed, after verification, within about a week as a rule
• I reply whenever I can, but it may take time alongside my studies. Thank you for understanding

Tech stack (bonus)

This site is built with Next.js 16 + React 19 + Tailwind v4 + TypeScript and hosted on Vercel. It is installable as a PWA and lets you read origin info and articles offline. Radar charts use Recharts, search uses Fuse.js, and the flavor wheel is a custom SVG implementation. The code is a hobby extension, so technical feedback is welcome too.
