A global wine solutions company, Vinventions – in partnership with Jet Technologies – has launched a decision-making tool that instantly measures the polyphenol content in must (early stage wine) and wine at different stages of the winemaking process – the NomaSense PolyScan.
The polyphenols in wine determine many of its sensory properties, such as appearance, colour, acidity and overall flavour – while also influencing its stability throughout the oxidation process, making the management of polyphenol content crucial to wine quality.
Serving as the ideal solution to manage and measure the polyphenol during their extraction, the NomaSense PolyScan allows winemakers to manage the critical elaboration phases of the winemaking process, such as pressing or fermentative skin contact.
“The more you go back to the beginning of the winemaking process, the more you understand that polyphenols are an incredibly important factor to driving the oxidative evolution of wine,” Vinventions general manager Asia Pacific Marc Schelcher said.
“With over 15 years of research into understand the influences that both polyphenols and oxygen have on wine, we wanted to expand the decision-making tools that support the winemaking process. This led us to developing the NomaSense PolyScan.”
As one of Vinvention’s first IoT connected devices, the PolyScan works to manage and measure the polyphenol content in wine and must with pre-calibrated electrodes – with all results produced in real-time.
“To interpret this real-time data, the PolyScan analyser splits the results into two separate measurements of concentrations – EasyOx and PhenOx – which are used to determine the correct course of action to take to ensure wine quality,” Schelcher said.
“EasyOx represents wine with easily oxidizable compounds, which are rapidly involved in oxidation reactions, where PhenOx represents the total oxidizable compounds (total polyphenols). Each of these representations can define whether a wine’s polyphenol content needs to be reduced or eliminated at the beginning of the winemaking process.”
According to Jet Technologies general manager Daniel Malki, Vinventions has been a strong partner for years. The new launch will be an integral tool for winemakers looking to perfect the early stages of the winemaking process by correctly managing polyphenol content.
“In collaboration with Vinventions, we’re excited to bring this important innovation to Australian winemakers,” Malki said.
