JF - Wine Studies JA - Wine Stud VL - 2 IS - SE - Original Articles DO - 10.4081/ws.7172 UR - https://www.pagepressjournals.org/wine/article/view/7172 SP - AB - To investigate claims that products containing weak stationary magnets can reduce the astringency of tannic red wine, a double- blind randomized trial was carried out, in which 96 paired tastings were conducted of magnetized and non-magnetized samples of a young Nebbiolo. The data showed no association between reported differences in astringency and actual difference in the magnetic treatments given to the wine (χ<sup>2</sup>=0.135, degrees of freedom=1, P=0.71). This study confirms an earlier work that magnets have no observable effect on red wine. ER -
