E-tongue can detect white wine spoilage earlier than people can

Whereas the digital tongue bears little bodily resemblance to its namesake, the strand-like sensory probes of the ‘e-tongue’ nonetheless outperformed human senses when detecting contaminated wine in a current examine. In a current experiment, the e-tongue recognized indicators of microorganisms in white wine inside every week after contamination — 4 weeks earlier than a human panel observed the change in aroma. This was additionally earlier than these microbes might be grown from the wine in a petri-dish. Winemakers historically depend on these two strategies, sniffing the wine and petri-dish testing, to determine potential wine ‘faults’ or spoilage.
