The white grape variety originates from the border region Italy/Switzerland. Synonyms are Blanc de Maurienne (Savoie), Petit Prié Tardif, Regis, Resi, Rèze Blanc, Rèze Blanche, Rèze Jaune, Rèze Vert, Rèze Verte and Rèzi. According to several DNA analyses cited in Wine Grapes, a parent-offspring relationship is said to exist with the varieties Arvine, Arvine Grande, Diolle (all three Valais), Cascarolo Bianco (Piedmont), Groppello di Revò and Nosiola (both Trentino). However, no parentage is given in the VIVC catalogue. In 2008, a colour mutation with red berries was found.
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.
