I could see a reasonable argument being made in that direction! I personally always felt that he was asexual - so dedicated and obsessed with his wine and family business that he never had time for anything else.
That is an excellent response, Dirk. Absolutely agree that wine was, for all intents and purposes, his lover. Sad but also emphasizes his anger when Rick tells him about selling the land to the Marino Brothers... (THE MARINO BROTHERS?!?!? THE MARINO BROTHERS?!?!?...they don't make wine....they don't even make a good mouthwash!)
