The South Australia University, in collaboration with Spanish scientists, develops an electronic tongue that analyzes the quality of wine and its ageing
Scientists have developed an electronic tongue that reveals the age of a wine, the type of barrel used and its quality. Although not the first to be created, this electronic tongue does represent a new horizon in the advance of technology towards the objective analysis of wines.
The “tongue” is made of gold, platinum and carbon electrodes, and measures the electro-chemical signals of sugars, phenolic compounds and other compounds present in wine, according to its developers. They added that it could even be used to predict critics’ scores.
The electronic tongue has been tested with the help of a Catalan Institute of Wine, INCAVI, which provided samples of wine, needed information about them and carried out sensory analysis. Analyzes of large sample sets will soon be carried out to further demonstrate the efficacy of this ‘tongue’, as well as to explore new functionalities.
