German Riesling. Good point. The stuff you can buy here is abysmal and ruins the reputation of German wine (unless you go to super specialty stores and pay prices that necessitate a double scotch on top of the Riesling).
The German Deli in Dallas should have most of the pre-packaged items. At my local Fiesta supermarket in Austin I can even get three different kinds of Dallmayr Prodomo coffee.
