Circo Vino produced seminars and tastings featuring wines from the east end of the Wachau and the west end of the Kremstal, immediately north and south of the Danube,  on 13 July in Los Angeles and  14 July in San Francisco.  Emmerich Knoll presented Knoll wines from the Pfaffenberg  vineyard; John Haeger presented Steinbuehl vineyards on behalf of Michael Malat.  Andreas Wickhoff MW presented Tegernseerhof wines from the Steinertal vineyard.  John Haeger moderated.  Additional wines from other producers were offered at a walk-around tasting that followed.  For convenience, the event was dubbed Four Corners: Wines from the Danube Valley where the Wachau and Kremstal Meet.  The tasting book is found here: FourCornersSeminarJuly
