The white grape variety (breeding number Würzburg B 48-21-4) is a new cross between Müller-Thurgau x Siegerrebe, which was confirmed by DNA analyses published in 2012. The cross was made in 1948 by grower Dr Hans Breider (1908-2000) at the Bavarian State Institute in Würzburg. The grower named it after his favourite philosopher, the Spanish poet José Ortega y Gasset (1883-1955). Plant variety protection was granted in 1981. Incidentally, the three new varieties Muscabona, Tamara and Thekla also originated from the same parents.
The early-maturing vine is sensitive to spring frosts, susceptible to botrytis (grey rot) and coulure, but resistant to both types of mildew. It produces floral, rather low-acid white wines with a peach flavour and ageing potential if matured appropriately. It is also used as table grape.

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.
