As I said in the comments:
one of the more interesting papers I wrote in college (long ago) was a review of a history book about women in foreign policy. The main thing I remember about the book was that, in most cases, women in foreign policy seemed to have more in common with "foreign policy people" than they did with "women in general".
I'd guess the same is true for women who go into winemaking (or maybe every profession that's a calling). The calling trumps the gender, or ethnicity, or any of those other demographics.
I'm looking forward to the follow-up...
