Glera, also known asProsecco, is a whitevariety ofgrape of Slovenian and Italian origin, possibly from the traditionally Slovenian-populated village ofProsecco on the Slovenia-Italy border, now in Italy. The variety was formerly mostly referred to as Prosecco, but in the EU was renamed "Glera" in 2009 to make room for the protection of "Prosecco" as the name of the Italian geographically-protected wine.
Glera is a rather neutral grape variety which is mainly cultivated for use insparkling Italian wine styles,frizzante orspumante, from the various ProseccoDOCG andDOC areas, although still wines also exist.[1]
It is grown mainly in theVeneto region of Italy, traditionally in an area nearConegliano andValdobbiadene, in the hills north ofTreviso.
Glera is believed to be an old variety, and the nameProsecco was derived from the villageProsecco nearTrieste, where the grape may have originated.[2] It has been proposed that it was cultivated already inRoman times,[3] possibly as thevinum pucinum praised byPliny the Elder, although that is not known with any certainty. It ranks about thirtieth in importance among the country's some 2,000 grape varieties.[4]
Prosecco was traditionally used as the name for the grape variety. In Italy, it was also used more specifically for sparkling wines produced primarily from it, such asProsecco di Conegliano e Valdobbiadene,Prosecco di Conegliano andProsecco di Valdobbiadene, all of which hadDOC status, and there was also an IGT zone surrounding them. When the higherDOCG status was sought for Prosecco di Conegliano e Valdobbiadene, it became a complication that the grape (which had become cultivated over a larger area, including outside Italy) and theprotected designation of origin had the same name. To resolve the issue, within the EU the old synonym Glera was officially adopted for the variety at the same time as the DOCG was approved in 2009.[5][6] The change reduced the ability of other producers (in Italy and overseas) to label sparkling wines made elsewhere as "Prosecco" by using the grape variety's name.[7]
The name change was rejected by wine producers outside Italy, and leading wine experts including Jancis Robinson MW, Julia Harding MW and José Vouillamoz, who continue to refer to the grape variety as 'Prosecco'.[8]
Glera is a parent variety of twoManzoni grapes, thered wine grape variety Incrocio Manzoni 2.15 (a crossing withCabernet Sauvignon) and another red skinned variety known as Incrocio Manzoni 2.14 (a crossing withCabernet Franc).[9]
Glera is also known under the synonyms Ghera, Glere,Prosecco, Prosecco Balbi, Prosecco Bianco, Prosecco Nostrano, Prosecco Tondo, Proseko Sciprina, Serpina, and Uva Pissona.[10]
