The Global Coffee Supply Chain — From Ethiopian Farm to $7 Latte

Coffee is a $500 billion global industry. The farmer who grew your espresso earned about 1-2% of what you paid. Here's how value is distributed across the global coffee supply chain.

The World's Second Most Traded Commodity

Coffee is the world's most widely traded agricultural commodity and the second most traded commodity overall after oil — though this ranking is contested depending on measurement methodology. Approximately 170 million bags (60kg each) of coffee are produced annually, worth approximately $20-25 billion at commodity prices. By the time that coffee reaches consumers as beverages, retail beans, and food service cups, the industry generates approximately $500 billion in annual revenue.

The $475 billion gap between farm gate value and consumer value represents the enormous value addition — and value extraction — that occurs in roasting, branding, distribution, and retail. The farmer who grew the coffee captures 1-2% of the final retail price in most cases.

This connects to Germany's Mittelstand and to ai infrastructure buildout.

The Supply Chain Layers

Farm level: Coffee is grown in 70+ countries within the 'coffee belt' (between the Tropics of Cancer and Capricorn). Ethiopia, Brazil, Colombia, Vietnam, Indonesia, and Honduras are the largest producers. Most production comes from smallholder farmers with 1-5 hectare plots. A smallholder in Ethiopia earns approximately $0.50-1.00/pound for green (unroasted) coffee beans.

Exporters and mills: Coffee cherries are processed (dried or washed) into green beans at wet mills, then dried at dry mills. Exporters aggregate, grade, and sort green beans for export. This is where significant value is captured through quality grading — specialty grades command $2-4+/pound vs. commodity grades at $1-1.50/pound.

Commodity trading: Green coffee is traded on the Intercontinental Exchange (ICE) in New York (Arabica, traded as 'C Contract') and London (Robusta). The major commodity traders (including Sucafina, ECOM, Neumann Gruppe — the 'ABCDs' of coffee) dominate global green coffee trade.

Roasters: Green coffee is roasted — the step that transforms the bean's flavor profile. Major roasters: Nestlé (Nespresso, Nescafé), JDE Peet's (Douwe Egberts, Peet's Coffee), Lavazza, Starbucks. Roasters capture significant margin: green beans at $1.50/pound become roasted beans sold at $8-20/pound retail, or espresso shots sold at $0.75-1.50 each.

Retail and food service: Starbucks represents the apex of the value chain. A $7 grande latte contains approximately $0.50-0.75 in coffee input costs. The rest covers milk ($0.40), labor ($1.50-2.00), rent ($0.80-1.20), and Starbucks' 15-20% operating margin.

The Specialty Coffee Premium

Specialty coffee — beans scoring 80+ on the Specialty Coffee Association's 100-point scale — has created a parallel premium market where farmers can earn $3-10/pound for exceptional lots. Direct trade relationships between roasters and specific farms (as practiced by Blue Bottle, Intelligentsia, Counter Culture, Stumptown) redirect some value to producers while giving roasters marketing differentiation.

Ethiopia has been most successful at capturing premium value: the Ethiopian Coffee Exchange, established 2008, and geographical indication protections for Yirgacheffe, Sidama, and Harrar origins have given Ethiopian producers more negotiating power. Ethiopian coffee now regularly fetches $4-8/pound at auction for premium lots.

Climate Vulnerability

Coffee arabica grows only in specific altitude and temperature ranges — typically 1,000-2,000 meters elevation, 15-24°C. Climate change is shifting these ranges upward and reducing suitable growing area. Brazil — the world's largest coffee producer — experienced severe frost (2021) and drought (2020) in its main growing regions, contributing to price spikes.

The World Coffee Research organization estimates that 50% of current coffee-growing land will be unsuitable for arabica by 2050 under moderate climate scenarios. This creates both a supply risk and an opportunity for higher-altitude growing regions (parts of Uganda, Tanzania, Ethiopia) that may gain suitable land as lower-altitude areas become too warm.
