The white grape variety comes from Austria or Croatia (or former Austro-Hungary). In the VIVC catalogue the three varieties (possibly varieties) Blue Barthainer, Green Barthainer and White Barthainer are listed with partly identical synonyms:
Nothing is known about possible relationships of these three varieties with each other or with the Hungarian variety Javor Groß with partly the same synonyms (Javor, Jauer). Likewise, there is no information about the parentage (parenthood). It is suspected that the variety Grüner and/or Weißer Barthainer is probably identical to the South Tyrolean variety Fraueler (Frauler), but this has not yet been confirmed by DNA analyses. In 2016, no stocks were reported under the above mentioned names (statistics Kym Anderson).
