I work for a German company have spent extended period working on projects throughout Germany. This have given me the opportunity to sample some really great German and Austrian wines of many types and varietals.
Unfortunately many of the great Tuetonic grape varietal wines just don't make it here. For instance it is near impossible to find a good bottle of Domina (love this stuff), Portugieser , Schwartzreisling (Meunier), Trollinger, lemberger, St Laurent, Regent, Zweigelt (another favorite as a rose sparkler), or even Dornfelder. For whites it's difficult to find a good German Bacchus, Kerner, Scheurebe, Gutedel, or even Silvaner (though I have been getting a relatively good one here from Hans Wirsching).
Recently, Spätburgunder, (German Pinot Noir) has been winning a lot of accolades in international blind pinot wine tastings (seems global warming has done wonders for this grape in Germany and Austria) and getting a fair amount of press. It does seems that more and more good German Pinot is becoming available. I love the Meyer Nakel "S".
But I don't understand why is there seems to be such little interest in general from American wine drinkers for German and Austrian wines. I suspect it is because in these places it is still largely a family affair with smaller vineyards and there are much smaller production from individual wineries and thus they just don't make it for export?
