Mulled Wine

What kind of wine do you use? I see dry wine in the recipes, but I can't imagine that you would want to use something good, right? Since all the flavoring is going to take over, I'd imagine it would be a cheaper Cab or what?

Nothing expensive
I’ve done cabs, Malbec, Pinot noir or merlot

Frankly I think they all come out tasting pretty much the same
