I know nothing about wine. I don't drink wine. Frankly, it all* tastes like vinegar to me.
However, occasionally we need wine for something (usually to take to someone else's home, because turning up with wine is the Done Thing), and I am sent off to Sainsbury's to get some.
My current tactic is "Look for something for around £5-£7, knocked down from a more expensive price." on the grounds that it should be a bit better than the standard stuff going for that price. But equally, it could be that it's knocked down because nobody is willing to spend £9 on it, because it tastes awful.
Anyone care to recommend a _simple_ guide to how to spot something that's not going to make people retch, for a reasonable price? Or am I already using an optimal heuristic?
*Very occasionally I will find a red wine which doesn't have an overwhelming taste of bitter vinegar to it, and tastes a bit more like port, which I can drink. But even then it's not actually something I'd seek out.
