Well I for one don't care for the taste. It's not that cheap either. At best you can find one that is inoffensive. Why would I spend money and effort going to a bottle shop for something I regard that way? Drinking it at home confers no social benefits, confers no meaningful health benefits either, nor is it the cheapest method of getting drunk if that's what you're after.
Some of the sweeter ports are pleasant. I basically only drink water now though.
