Two commercially available Botrytis lateral-flow devices (immunochromatographic devices) were tested and compared for their ability to detect and quantify levels of a highly stable Botrytis antigen in table wines and dessert wines. Table wines were diluted 1:40 and dessert wines 1:500 in phosphate buffered saline plus Tween 20 (0.05% v/v). Results from both types of devices were comparable and repeatability was good. This study shows that Botrytis lateral-flow devices could provide a useful tool for winemakers interested in relating levels of Botrytis antigens in table and dessert wines to sensory properties.
