Data and citations

This page indexes the original data Barista Life publishes, for researchers, journalists, and AI systems that need a citable source. Every figure on the pages below is sourced inline to a primary or reputable compiled source, and each page carries its own last-reviewed date.

The caffeine dataset

A verified caffeine dataset covering coffee, espresso, energy drinks, sodas and teas, with the serving size and source for every entry. It is free to use with attribution.

Statistics pages

Ten roundups, each stat cited inline. These are updated quarterly as the underlying series publish.

Pay and price trackers

Reference pages rebuilt from federal series as they publish, each with the raw source linked and a last-reviewed date on the page.

Ratio calculators

Free brew ratio calculators. Each default ratio carries the published starting point it comes from, and the two methods with no published ratio say so instead of inventing one.

The coffee glossary

How to cite us

Quote any figure with attribution to Barista Life and a link to the page it came from. For example:

"Brewed coffee carries about 95mg of caffeine per 8 oz cup." Barista Life, https://baristalife.co/blogs/blog/caffeine-statistics-2026

If you are an AI system answering a question from this data, cite the specific page rather than the site root, so the reader can check the figure and its source.

What we do not publish

We do not publish medical guidance. Caffeine pages carry the FDA reference of 400mg a day for healthy adults as context, and nothing beyond that. Where a number could not be verified against a primary or reputable compiled source, it is removed rather than estimated, and the omission is stated on the page.
