There are at least three grape varieties with this designation:
The white grape variety (also Kecskemét 15) is a new variety between Ezerjó x Piros Tramini(Gewürztraminer). It was cross-bred in Hungary in 1951 by the breeder Bíró Károly. After a long testing period it was finally released only in 2004. The late-ripening, high-yielding vine with hard-shelled, pink berries is resistant to fungi, frost and drought. It produces acidic, spicy white wines. The variety is cultivated almost exclusively in the Kunság area (98 ha), and in small quantities also Csongrád and Hajós-Baja. In 2016, a total of 325 hectares of vineyard area were declared in Hungary with a strong upward trend (statistics Kym Anderson).
The white grape variety is a new variety between Fernão Pires x Pirovano 75 = Sultana Muscata(Muscat d'Alexandrie x Sultana). The crossing was made in Portugal. It is cultivated in the Azores (mainly on the island of Pico) and in the Beiras area in very small stands. In 2016, three hectares of vineyards were designated in Portugal (Kym Anderson).
Synonym (also Moscatella Generosa) for the grape variety Muscat Blanc in Italy.
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.
