We stopped drinking wine with dinner during the week, so now more often than not it's "special occasion" stuff which I will have layed down between 10 and 30 years ago. In today's prices from a retailer, probably £50-300, but I would never pay that much.

For a non-special occasion, or when the children are around, it would be about £10 per bottle at which price point, if you avoid the supermarkets, you can get some excellent wine.

I was intrigued that, at my US home this summer, with a whole lot of guests, I was serving an Italian Sangiovese which I had bought at a merchants in SF for $8 plus tax. We went wine tasting in Sonoma and found several Sangioveses, the cheapest of which was $39 plus tax. None were nearly as good as the cheap Italian one - not surprising really, but confirmed my views on Californian wine.
