Signs of Spoilage
- •Rancid or sour smell in beans or grounds (different from normal coffee aroma)
- •Visible mold on beans, grounds, or brewed coffee
- •Significant loss of aroma in whole beans or grounds

Storage & Reheating Tips

- •Store coffee in an airtight container made of ceramic, glass, or non-reactive metal
- •Keep coffee away from heat sources, direct sunlight, and moisture
- •Don't store coffee in the refrigerator as it can absorb odors and condensation
- •If freezing coffee, divide into small portions to minimize exposure to air when retrieving
- •Allow frozen coffee to reach room temperature before opening to prevent condensation
- •Clean coffee makers regularly to prevent oil buildup that can make coffee taste rancid
- •Brewed coffee can be refrigerated and used for iced coffee within 3-4 days
