Green coffee has a grassy, hay-like aroma and contains the precursor compounds — sugars, amino acids, chlorogenic acids — that generate flavor during roasting. Properly stored in GrainPro or Ecotact bags at stable humidity (50-60%) and temperature (20-25C), green coffee can maintain quality for 12-18 months. Water activity below 0.60 aw is the key metric for shelf stability.
