Revolutionizing Wine Fermentation Monitoring with Fiber-Based Spectroscopy

Ever wondered how you can monitor wine fermentation in real time without disturbing the process? In our latest application note at art photonics, we explain how the combination of mid-infrared (mid-ir) and uv-vis spectroscopy with fiber-based technology is transforming fermentation analysis. Our study on Federweißer (fresh wine) revealed that key ethanol peaks become clearly visible […]
