Mantlerhof is a winery located in Kremstal, Austria.
Kremstal is one of 8 regions in "lower" Austria (Niederosterreich)
Wachau is perhaps the best known of the 8, and contains some of the top, even Robert Parker (ooo!) recognized wineries. Here, Riesling is king, and the Austrians rather like to think this is where the grape originated. (however, this is also the place where some of the very best Gruner Veltliners are made, and with it's steep terraced terrain, you can really taste the crisp minerals in the wine.)
Kremstal and Kamptal produce some wines that are equal in quality to those of the Wachau, which shouldn't come as a huge shock since the western part of Kremstal is geologically identical to its better known neighbor. Then in the Kamptal there is this enormous crag around which the old vine Rieslings yield their comparable candidates.
I realized that up until now I was being quite rude and not signing my posts, so I hope this info helps, Emily (winemonger)
