Black Tower, Rivaner 2008
When you find a bulky black bottle that looks like it holds Black Forest schnapps or some unspeakable cod liver oil in your supermarket, it will almost certainly be a German wine: Black Tower, a brand designed for the UK mass market. Perhaps it makes the Brits think of German Gemütlichkeit of the rustic type.
I was actually after the Black Tower Liebfraumilch, but as I could not find it I went for this Rivaner for £3.88 instead (Rivaner, btw, is another name for the grape variety Müller-Thurgau, if you wondered).
