@hightor,
I'm not much of a drinker any more, but i used to buy Vella cabernet in a box. Equivalent of 5 bottles for $15-20. It's the best red I've ever tasted. Liked it so much I wated it down so as not to get drunk and it still was good.
I remember reading a Gore Vidal novel, "Creation" I think it was. Part of it took place in ancient Persia. When the royals had a party, the man who provided the wine would decide if it was going to be a drunk fest or conversation party. If the latter he would water the wine down.
