This is the first known large-scale study in the literature to examine women in the wine industry. By investigating the top wine-producing states in Australia and using a unique database, women across CEO, winemaker, viticulturist, and marketing roles are tracked for the years 2007-2013, resulting in 16,763 firm year observations. By relying on social identity theory, a hypothesis is put forth that women’s representation in top roles is actually less than predicted. The hypothesis is confirmed. A hypothesis is also posited that women in South Australia have higher representation in top roles than women in any other wine-producing state. The hypothesis is partially supported. Finally, this study hypothesizes that were a wine firm has a woman CEO, the likelihood of women representation in the other roles studied increases, which finds support. The results are discussed, along with future research directions and limitations.
