About decaf.info

A plain-English guide to caffeine, decaf, and paraxanthine (Px) — for the millions of people who love coffee but are tired of paying for it in lost sleep and frayed nerves.

We started decaf.info because the honest information here is scattered and often wrong. "Is decaf chemical?" "Does decaf have caffeine?" "What is paraxanthine (Px)?" These deserve clear, sourced answers — not marketing.

decaf.info is published by Rarebird, which makes a paraxanthine coffee. We're upfront about that on how we rank. Our aim is to be useful first; the products we recommend, including our own, have to earn it on the facts.

The scientist behind it

The paraxanthine (Px) breakthrough this site keeps returning to came from one person: Jeffrey Dietrich, PhD — co-founder of Rarebird and co-holder of the paraxanthine-in-coffee patent. Meet the scientist →
