The white grape probably comes from Istria-Croatia or from Veneto-Italy. Synonyms are Ghera, Glere, Grappolo Spargolo, Prosecco, Prosecco Tondo, Serpina, Serprina, Serprino, Uva Pissona ( Italy ); Briska Glera, Gljera, Steverjana Slovenia ); Beli Teran, Teran Bijeli ( Croatia ). Despite seemingly indicative synonyms or morphological She may not share similarities with the varieties Glera Lunga (Prosecco Lungo), Malvasia Bianca Lunga (Prosecco Nostrano) or Perera be confused. Until 2009 the officially valid main name was Prosecco (Prosecco Tondo); the change on Glera has resulted in some confusion.
According to an unverifiable hypothesis, the variety is already in the antiquity for the of Pliny the Elder (23-79) mentioned famous Pucinum have been used. In the late 18th century, in the province of Treviso-Veneto, several morphologically distinct varieties were called Prosecco. There is also a community of this name, which is also called in most sources as a "birthplace". In the middle of the 19th century, in the hills of the municipalities of Conegliano and Valdobbiadene, Count Balbi Valier selected a special variety with round berries and called Prosecco Balbi or Prosecco Tondo (round). (The variety was then crossbred partner of the new breed Incrocio Manzoni 2.15 ). In the 1980s were from the institute Conegliano two further varieties selected for research purposes were Prosecco Lungo with oval berries (lungo = long) and Prosecco Nostrano (nostro = our).
Several DNA analysis between 2003 and 2009 showed that they are not varieties but three distinct varieties. Prosecco Tondo (Glera) was now called Prosecco and Prosecco Lungo (Glera Lunga) kept its name for the time being. Prosecco Nostrano is identical to Malvasia Bianca Lunga, Although between Prosecco and Prosecco Lungo gives genetic similarities, one Parent-offspring relationship but can be excluded. The variety Vitovska (Vitouska) originated from a presumably natural cross between Prosecco (Prosecco Tondo) x Malvasia Bianca Lunga (Prosecco Nostrano). As a conclusion to this revealing history, it emerged that the supposedly independent Slovenian varieties Briska Glera and Steverjana, as well as the Croatian Teran Bijeli are all identical with Prosecco.
In connection with the high qualification of the DOC area Conegliano-Valdobbiadene on DOCG Conegliano-Valdobbiadene Prosecco According to a decree of the Italian Minister of Agriculture of 17 July 2009, it was decided that from 1 January 2010 "Prosecco" would no longer be the name of a grape variety, but only one designation of origin is (confirmed by EC Regulation No. 1166/2009). The grape variety Prosecco (Tondo) was renamed Glera and the grape variety Prosecco Lungo on Glera Lunga. According to the Swiss biologist dr. José Vouillamoz but this is misleading. Because Glera is a general name for several different varieties. In addition, studies have shown that the term Glera refers mostly to Prosecco Lungo and less frequently to Prosecco (Tondo), Vitovska and others.
The late-ripening vine is sensitive to drought, as well as prone to both mildews. Flavescence dorée and millerandage, It produces straw to golden yellow, sparkling rather neutral white wines. Sometimes it has a nutty aroma and a bit of a bitter aftertaste. There has always been confusion about the name because prosecco has been and is often used as a synonym for a froth or sparkling wine. This is also wrong, because in addition to sparkling wine still wine (Tranquillo) is pressed from the variety. The variety is excellent for the production of pearl and sparkling wines.
In the Veneto widespread variety is in the DOC / DOCG wines Colli Asolani Prosecco. Colli di Conegliano. Colli Euganei (here under the name Serprina), Conegliano-Valdobbiadene Prosecco. Prosecco. Montello e Colli Asolani and Venezia authorized. The majority of over 90% is in the province of Treviso in Veneto. The rest is on other provinces of the region, as well as the region Friuli-Venezia Giulia distributed. In 2010, 18,255 hectares were recorded in Italy. Small acreages are also available in Slovenia and Croatia, as well as overseas in Argentina (10 ha) and Brazil (173 ha). In 2010, the variety (then still under the name Prosecco) occupied a total of 18,437 hectares. Compared to 1990 with 7,498 hectares at the time, this means more than double the amount. It thus proved in the worldwide varieties ranking the rank 42.
