TRENTINO represents the southern, Italian-speaking part of Italy’s alpine Trentino-Alto Adige region, whereas Alto Adige represents the German-speaking Süd-Tirol (South Tyrol) part to the north and bordering Austria, of which it was once part.
NATIVE WINE GRAPES
Dr Ian d’Agata (2014, p38-9) says most grape varieties local to Trentino have considerable genetic similarity, a result he says of cultivars sharing a limited alpine habitat not found on major human migration or commercial routes. D’Agata (ibid.) cites a 2000 study by Grando, Frisinghelli and Stefanini which showed identical vine genotypes had been given different but similar denominations eg. Biancaccia and Biancazza, or Schiava Grigia and Cenerina (so named for their copious ash-like bloom); and the unknown Nero di Baisi had alleles characteristic of non-Vinifera species, likely a naturally occurring cross between a European and American grapevine.
NATIVE WINE GRAPES–RED / Dr Ian d’Agata says that Trentino’s main native red grapes are Teroldego and Marzemino. Teroldego wines age extremely well and their herbaceous, tannic, and bitter side has been tamed (smoky, red fruit) to the extent Teroldego is now also being planted in other Italian regions (D’Agata, ibid). The lighter red Marzemino grape remains a local variety for now (D’Agata, ibid). Other common Trentino native grapes include members of the Schiava group (which are also typical of Alto Adige) whose light-bodied reds resemble rosés. Unknown Trentino red native grapes include Rossara, and Enantio which is also known as Lambrusco a Foglia Frastagliata (D’Agata, ibid). Some ‘local’ grapes like ‘Vernaccia Nera’ and ‘Francesa’ were found to be Merlot and Carmenère respectively, D’Agata (ibid) adds.
NATIVE WINE GRAPES–WHITE / Trentino’s most important native white grape is Nosiola.
