I can understand that in the old days non-Jewish people used to make wine for worshipping or that wine was the main alcoholic beverage and drinking a wine made by non-jews would require some interaction with the producer, causing you to marry his daughters.
Nowadays, the worship reason is practically unexistent. While the reason for marring a goy is applicable for any other alcoholic beverage. Logically, it seems more likely that someone would marry a goy by drinking a kosher vodka in a non-Jewish bar than by drinking a bottle of wine with his Jewish wife in its own place.
So what is the reason for such strict laws regarding wine nowadays?
