A recent study has uncovered the complex relationship between coffee roasting methods and caffeine content. Researchers from Berry College focused on Ethiopian coffee beans to determine the optimal brew that balances flavor and caffeine kick. Their findings challenge common beliefs about dark and light roasts, suggesting that medium roasts may offer the highest caffeine levels per cup.
• The study analyzed various roasting techniques and brew times using Ethiopian coffee beans.
• Researchers utilized advanced methods like high-performance liquid chromatography and scanning electron microscopy to assess the coffee's chemical properties.
• Results showed that light and medium roasts generally have higher caffeine content than dark roasts.
• The study established a clear link between roasting degree, caffeine levels, and extraction yields.
Understanding these relationships is crucial for coffee enthusiasts seeking the best brew for energy. This research not only informs brewing practices but also enhances our appreciation of coffee's rich chemistry.
