This is a "classic example" of how food/wine or cheese/wine pairings don't always have a "classic wisdom" to them. Harvey Steiman said the same in one of his blogs last year: just pair whatever wine you want with whatever dish you want. Are there, gastronomically speaking, better pairings than others? Sure. Are there any "wrong" pairings? No. Why don't you go buy some Manchego, and try numerous different types of wine with it. Let us know what you think. ... after all, you should only be concerned with your own opinion on this matter anways.
