Scope
Main Technical Content: (1) Coffee Bean Grading 1. Grading Criteria. To fully reflect the characteristics of coffee trading in Kunming, coffee beans must meet the requirements of the "Product Quality Safety Indicator System for Green Food Industry Trading Platform in Kunming - Raw Coffee". The grading criteria include six indicators: coffee bean variety, altitude, sensory indicators, particle size, impurities and defective beans, and cup test. 2. Grading Levels. To facilitate trading operations, coffee beans are divided into three grades based on a comprehensive scoring system: - Level 1: 100–90 points - Level 2: 89–76 points - Level 3: 75–60 points 3. Scoring Calculation Formula. - Variety accounts for 15% of the total score to encourage the cultivation of high-quality varieties. - Altitude, sensory indicators, particle size, impurities, and defective beans account for 25% each. Altitude reflects the impact of growing altitude on coffee bean quality, while sensory indicators, particle size, and impurities/defective beans reflect the effects of harvesting and processing on coffee bean quality. - Cup test accounts for 60% of the total score. (2) Coffee Varieties The main coffee varieties grown in Yunnan include Catimor, Geisha, and Typica. Among them, Catimor, with its high yield and resistance to pests and diseases, accounts for the largest planting area, but its quality is inferior to Geisha. To highlight the advantages of varieties in trading and encourage growers to plant high-quality varieties, a coffee trading variety scoring table was developed based on international coffee standards and Yunnan's unique varieties. - Geisha (Gesha) and Typica: 90 points - Pacamara and SL28 (Scott Laba): 85 points - Bourbon, Sarchimor, Yunka 1, and Yunka 2: 80 points - Mundo Novo, Caturra, Dhez 132, and Dhez 296: 75 points - Catimor, Conillon, and Robusta: 70 points (3) Altitude Altitude can affect coffee growth and quali
