Cover Story: Cold climate cultivars have a shorter history than vinifera varieties. In this study, a method was developed using headspace solid-phase microextraction coupled with simultaneous chemical and sensory analysis to evaluate the aroma profile of seven Iowa red wines originating from four different cold-hardy grape cultivars. Among the 36 aroma compounds identified, isoamyl alcohol, ethyl caprylate, benzeneethanol, ethyl decanoate and ethyl caproate are the top five most abundant aroma compounds present in headspace. This information is useful to help determine the appropriate wine styles for these new cold-hardy cultivars. View the paper here.
