These wines have a more masculine feel. The bright blue although obnoxious, it has a crest of sorts on the front that males are drawn more to. Greg Norman is a professional golfer, and odds are that most of the men would know that and not the females.
These are wine that I have purchased for myself. Although I am clearly female, I prefer to go towards wines that do more marketing towards a wine connoisseur and less towards a gender. I think those not only in appearance, but thank goodness taste also are way better. Let the wine be wonderful, and don't fall for those sneaky marketing ploys.
