What Makes Coffee Beans Oily? The Role of Roasting and Storage

✨ Roasting level matters: Darker roasts have more oils on the surface, while lighter roasts retain more moisture and have fewer oils.

🔬 Chemical reactions during roasting create new flavor compounds, break down sugars, and transform green notes into rich flavors.

🌡️ Factors affecting oiliness include roast level, coffee bean variety, storage conditions, and bean age - all of which impact the final flavor profile.

👀 Oily beans deliver a bolder flavor, with concentrated taste compounds and a fuller body, but excessive oil can mask subtle flavors.

📦 Store beans properly to preserve flavor: use an airtight container, avoid light and heat, and use beans within two weeks of roasting for optimal taste.
