The exact origin of the white grape variety is uncertain; it could come from Germany, France or the Czech Republic (Moravia). The different varieties differ in berry colour, aroma, leaf shape and cluster size, as well as in vigour, yield and susceptibility to disease, but they have almost the same DNA profile with minor differences. They are therefore considered as a single grape variety, although they are very much listed separately as distinct varieties in many grape variety catalogues. There are the following three main varieties:
Savagnin Blanc (France) or Gelber Traminer, Weißer Traminer, Traminer (German-speaking area): The French name (also Savagnin) is mostly given in international sources. Whether it is actually Weißer Traminer or Gewürztraminer is not always clear. This variety is characterised by odourless, yellow-green berries.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.Thomas Götz
