Liseiret is one of the Italian versions of the Gouais blanc, one of the most famous grape varieties as today the most neglected. As it is well known, its fame derives from being the parent, together with Pinot, of a large group of important varieties including Chardonnay and Gamay (Bowers et al., 1999). Besides, Gouais gave rise, or is genetically linked, to a truly impressive group of cultivars, both in France and in other European countries (Lacombe et al., 2013), so that it has rightly been considered a key grape of the European genetic heritage (Boursiquot et al., 2004). The historical references to Gouais blanc are remote, dating back to late 1200s when in France a "Goet" is mentioned (Berget, 1903). Gouais’ presence in the European vineyards subject to difficult climates was very wide in the past. This variety in fact, fertile and very rustic, is able to offer a generous yield, as often as mediocre, even in the less favourable years or environments.
As to its presence in Piedmont in the old times, the local synonym Liseiret used in Alta Val Bormida is historically reported as Oserietto or Useriello (Di Rovasenda, 1879). The same text mentions another local variety under the name of Blancho (White) dominant among the white grapes in the municipality of Stroppo (Val Maira). Blancho has been recently identified as Gouais. Moreover, numerous samples of a white Perveiral with a description fully responding to Gouais came to the Ampelographic Exhibition of Pinerolo (Provana di Collegno, 1883).
