First of all, you shouldn't have to pay more than €20 for really good white Burgundy, and I get it for even less sur place.

As for expensive wines being mishandled, I certainly don't think you can blame the entire Burgundy region if your wine is mishandled. Maybe come here and purchase it yourself and arrange your own shipping? That's much more fun anyways. And you can taste it yourself before you buy to be more certain of the quality. You can even watch the corks being put in the bottle if you like at most places here.
