Roger, Have you tried looking in Germany?
The newspaper "experts" quite often recommend certain german wines - not as often as the other regions, but they crop up every couple of months. They're usually not cheap'uns, so I haven't bothered seeking them out!
I mainly get my plonk in supermarkets, and find the New World stuff (mainly Chile!) much nicer than Europeans down at the £3-£5 end. But I know my palate is far from educated.
