Clean Cup: What It Means in Coffee Quality

A clean cup is coffee without distracting sensory defects that obscure the intended flavor profile. Clean does not mean bland, washed-process, low-fermentation, or low-intensity. A natural or experimental coffee can be clean if its fruit and fermentation character are controlled, coherent, and free from defect-like phenolic, moldy, dirty, or contaminated notes.

How Shade Changes Coffee Maturation and Quality

Shade can change coffee maturation by modifying temperature, radiation, soil moisture and water stress.
