Origin-Specific Standards MOC¶

Coffee-producing countries have developed unique grading systems, quality standards, and cultural practices over decades or centuries. What qualifies as "Grade 1" in Ethiopia differs dramatically from "Grade 1" in Indonesia, and a Colombian "Supremo" is classified entirely differently from a Kenyan "AA." This MOC organises country-specific coffee standards, helping you navigate the complex landscape of origin-based quality systems.

Understanding Origin Standards¶

Why They Exist¶

Historical Factors: - Colonial Legacy in Coffee Standards - British, Dutch, Spanish, Portuguese influences - Post-Colonial Evolution - How countries adapted inherited systems - Geographic Necessity - Different terroirs require different approaches - Market Positioning - National branding and differentiation
