Actually one of the nice things about the mass-produced "plonk" is that it is very consistent. One bottle of Barefoot cab will taste pretty much the same as another, whereas with more expensive wines you get a lot more variation, particularly from year to year. (Wine snobs consider this a feature!)

Whatever works! My wife likes vanilla vodka with olives, and raspberry martinis with a dash of tabasco. But I love her anyway :-)
