Yeast diversity related with Touriga Nacional Grape variety
Duarte, Filomena; Teixeira, A.; Ramos, P.; Gomes, Ana Catarina; Schuller, Dorit; Alemão, F.; Costa, Ana Catarina Moreira daThe diversity of yeast species related with the grape variety Touriga Nacional was evaluated at four distinct vineyards of three Portuguese wine regions. Samples were collected 48 h after crushing, and when the loss of CO2 reached 70 g/L. Restriction profiles analysis of 26S rDNA region with the endonucleases HaeIII, CfoI, HinfI, ApaI and MseI was used to characterize the five hundred and nine isolates obtained...

Wine purchase and consumption in Portugal - an exploratory analysis of young ad...
Duarte, Filomena; Madeira, Joana; Barreira, Maria MadalenaThis study, exploratory in nature, examines how motives/attitudes, purchase and consumption behaviour, as well as extrinsic attributes for wine choice, of Portuguese young adult’s (aged less than 35 years), differ from other age segments. With this aim an online survey was used, resulting in 1160 usable responses. Using factor and cluster analysis, based on motivation/attitudes towards wine consumption, four se...
The future of olive groves on sloping land and ex-ante assessment of cross comp...

This led to an intensification of production, particularly on flat land, and had inmost cases negative environmental effects, such as more soil erosion on sloping land and more pollution. With the decoupling of agricultural support under the newly e...
