How this guide is written

Each entry is researched from 1,135 sources (growers' associations, research bodies like World Coffee Research and Kew, roasters, historians) and published only after the text has been checked against them. Taste notes are what guides describe, never a promise about your bag. Unverified notes stay off the page until someone has checked them.
