This really depends on what you're using the wine for. A Rioja reduction stands on its own as sauce. On the other hand, very acidic wines when part of a reduction just taste very very very acidic. So it's best to avoid things like vinho verde and Albariño. Gewurtztraminer is pretty good at retaining its character in the cooking process and there is also Verjus especially for cooking certain dishes. There are three basic rules of thumb when selecting and using wine for cooking. First, use a decent variety; there's no point cocking up a dish by trying to save money on the ingredients, but this is more of an issue in the U.K. & U.S. where alcohol is heavily taxed. Second, match the wine to the ingredients much in the same way as you choose wine to drink with food. This may be a highly personal choice, but it should never be an arbitrary one. Finally, always boil off the alcohol (which will otherwise ruin the dish) and flame the wine before adding it to anything. It is debatable whether flaming actually alters the flavour of the reduction, but it is a way of actually seeing that the alcohol has more or less disappeared from the liquor, it is also quite dramatic and makes cooking more exciting. M'lud M, a very useful post, if I might say so. Though I, like so many (I have received several PMs), read most of thine posts while sheilding my eyes from thy radiance and feel exhausted and listless for several days afterwards I should like to see more of such comments tumble from thy fingertips and through the keyboard into our waiting optic nerves. Really. ediot: I can't spell "to". Sad.
