Synonym for the grape variety Rotweißer Veltliner, but sometimes also referred to as an independent variety, namely a mutation of Roter Veltliner. In any case, a variety is still cultivated under the name Silberweißer Veltliner in very small populations in Austria. In 2016, no stock was reported (Kym Anderson). See also under Veltliner.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
