In the summer of 2020, wildfires in Oregon brought devastation to the winemakers. The local community donated a large amount of juice and wine samples to support smoke taint research at Oregon State University. GC-MS studies related to guaiacols and cresols were conducted to find the fingerprint of smoke taint. This research was reported on 2022 Grape Day, by Michael Qian, professor of flavor chemistry at OSU/OWRI. Spectra Scientific was proud to contribute to the statistical data analysis, particularly in finding the multivariate signature of smoke taint chemicals.
