The white grape variety is a new breed between Silvaner x Müller-Thurgau, which was determined according to DNA analyses carried out in 2013. The paternity Rieslaner given in the breeding list turned out to be wrong. The name is derived from the Marienberg fortress in Würzburg. By the way, the same parents also produced the new crosses Diana (1) and Gloria. The cross was made in 1951 by Dr. Hans Breider (1908-2000) at the Bavarian State Institute for Viticulture in Würzburg, and variety protection was granted in 1971. It produces a yellow-green, delicately fruity wine with a peach aroma. In 2016, three hectares of vineyards were designated (Kym Anderson statistics).
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.Andreas Essl
