Wine and Cooking

I am not a trained chef (yes I know you knew that) but I have opinions about the best wine to use for cooking.

Asian food is routinely cooked with wine that is unfit for any other purpose.

Yet chefs always say never cook with a wine you wouldn't drink.
Well personally I don't agree.

I cannot taste the difference in most dishes between a good wine and a cheap one.

I doubt many people can, particularly in a slow cooked dish where the wine imparts a blended flavour.

For me I will keep my good wine for drinking and use only my cheap cask wine for the pot.

This may make me a philistine, but the good wine I get to drink!
