Coffee Sourcing Work / 寻豆工作

Definition

Coffee sourcing work is the repeated operational practice of finding, testing, comparing, and buying green coffee through samples, roasting, cupping, producer contact, and trade judgment.

Current Synthesis

The source treats sourcing as a disciplined bridge between the cup and the field. 余文杰’s work in 云南 shows that finding good coffee is not just discovering a romantic hidden lot; it requires sampling networks, sensory calibration, local residence, farmer contact, and judgment about whether a lot can become a viable purchase or direct-trade product.

Key Claims

• Sourcing depends on repeated sample handling: receiving beans, roasting samples, cupping, comparing, and selecting.
• Blind cupping helps separate cup quality from origin labels and seller descriptions.
• Long residence in a producing area can reveal small farmers, plots, and batches that ordinary trade channels may miss.
• Sourcing includes commercial judgment about direct trade, import, value, and product fit.
• The role connects sensory skill to supply-chain and agricultural reality.

• Producing-area residence: 咖啡时间：跟着寻豆师，找到能代表中国云南的咖啡豆 says living in Mangshi helped Yu Wenjie find small farmers, plots, and small processing batches.
• Commercial judgment: 咖啡时间：跟着寻豆师，找到能代表中国云南的咖啡豆 describes evaluating whether beans are suitable for direct trade or import.
