Blue Nun, or the German equivalent
Blau Nonne, possibly. In any case this was one of my lowest points of student drinking. Picture the scene of a 20 year old shamelessly walking out of a dodgy South London offy, Peckham 2004, with the cheapest/strongest booze his meagre student loan would allow at that point.

So I'd made it home with this wine without being mugged stabbed or shot, so to celebrate I poured myself a glass. It was utterly disgusting stuff, which I expected, but had such a sour aftertaste, like fruity curry farts or rotten citrus fruits (apparently the smell of rotting human corpses), I had to do something.

This was the point that I discovered that sugar does not dissolve in shit white wine (despite vigorous stirring, my wank-hand was strong), nor sweeten its taste, yet forms a glacier at the bottom of a glass, refusing to be involved in this atrocity against God and man.

Dear reader, I still drank it all, despite that first failed attempt at making it more palatable, because I'd paid for it and I'm fucking badass. In the intervening decade, I've drank some horrendous stuff, but none so much as made me actually want to add sugar to make it humanly palatable!

Ribena. Ribena can rescue terrible white wine.

Blue Nun was a brand of fairly innocuous white Rhine wine
that I occasionally used to try to loosen the morals of girls I used to date. It didn't have a lot of character but there was nothing really to object to. Girls that didn't drink a lot of wine tended to like it and I did have some success with it.

I don't know what you are on about with curry farts. Perhaps you imagined it all.

You add antifreeze to Germanic wine to sweeten it.

You do indeed.
One wonders whether Austrian supermarkets have meths in the fridge cabinets.
