Mulled wine season is rapidly approaching.
I've found, after exhaustive research. that it's best when the base is a very dry, very tannic red. The kind that makes your teeth feel that they've got several cm of plaque on them after a couple of sips.
Back in the day I'd have chosen Bulgarian Bulls Blood but, these days, the cheap reds that I've tried are all very "smooth" and "fruity". They're also crap but that's by the by.
Any ideas for cheap bottles from the major supermarkets that fit my criteria ?
