The Torrontés Riojano is an emblematic variety in the Calchaquí Salteño Valley. The obtaining of selected native yeasts is a tool of differentiation of the wines, highlighting unique characteristics of the terroir. Native yeasts were isolated from spontaneous fermentations of Torrontés grapes harvested in nine zones of the Valley. We obtained 45 isolates.
In the São Francisco Valley, Northeast of Brazil, tropical wines have been produced thirty years ago. Vines can produce twice a year and wine stability can change according to the harvest date. Normally wines elaborated from grapes harvested between November-December have a fast evolution, while wines from grapes harvested between June-July can have greater stability.
Rosciola is an antique red grape variety in the Lazio region (Italy) in the area between the Simbruini mountains and the high valley of Aniene. The name “Rosciola” is probably due to the light red color that the skin berries have to maturity. The oenological aspect was observed and evaluated over various vintages (Ciolfi G. et al., 2009).
Plant acclimation to the light environment involves changes in plant morphology, carbon- and water-physiology, yield and quality of harvestable organs.
