Real-time control and monitoring of the Alcoholic Fermentation Process. The wine industry loses about $500M a year due to failures during the alcoholic fermentation process. Fermentation is key and has a direct impact on a winery's production costs, production time, quality and therefore competitiveness in the market.

Errors can slow down fermentation rates or even stop it completely, which leads to repeat the whole process all over again or end with a less competitive wine with higher residual sugar and sensory defects.
