Why Should You Store Coffee in the Fridge?

Storing coffee in the fridge can help extend its shelf life and preserve freshness when done correctly. Refrigeration slows down the oxidation process that causes coffee to become stale, potentially keeping it drinkable for up to 2 weeks depending on the brewing method.

The Science Behind Coffee Freshness

Coffee begins to lose its fresh flavor profile almost immediately after brewing due to continued oxidation. When hot coffee cools, it undergoes chemical changes that affect both taste and aroma. Research from Healthline shows that exposure to air, light, and heat accelerates this degradation process.

The primary factors affecting coffee freshness are:

• Oxidation: Contact with oxygen causes chemical changes
• Temperature: Heat speeds up degradation
• Light exposure: UV rays break down flavor compounds
• Moisture: Can lead to bacterial growth
