余文杰 / Yu Wenjie

Overview

Yu Wenjie / 余文杰 is the 巴比特咖啡 practitioner interviewed in 咖啡时间：跟着寻豆师，找到能代表中国云南的咖啡豆 about Yunnan coffee.

Current Profile

The source presents him as a coffee operator turned sourcing and product person. His authority in the episode comes from repeated origin visits, a long stay in 芒市, direct contact with farmers and small lots, and routine work in roasting, cupping, sample comparison, purchasing, and trade judgment.

Key Characteristics

• Works close to the upstream coffee chain: samples, roasting, cupping, sourcing, purchasing, and direct-trade assessment.
• Uses blind cupping to counter inherited origin labels and reduce expectation bias.
• Treats 云南 coffee as an origin with its own terroir, varieties, limits, and commercial route.
• Gives strategic weight to Sarchimor because it can connect local flavor, yield, disease resistance, and farmer income.
• Keeps quality claims bounded when he lacks direct cup evidence, such as some high-altitude plots he has heard of but not tasted.
