If I think about austrian winebloggers, the very very first one I have to mention is Bernhard Fiedler.
Bernhard Fiedlers We(in)blog is a wineryblog, I would even say the best german language wineryblog existing! Talking about Austrian wine, internet and web 2.0 without mentioning his name would be a joke.
So if you are able to understand the german language, Bernhard Fiedlers We(in)blog should have a place in your blogroll and Feedreader!
