Interspecific vs. Traditional varieties for rosé wines production

This study was aimed on comparison of interspecific and traditional varieties suitable for rosé wines production. For samples of wines - Laurot , Cerason , Merlan ,three interspecific Czech varieties and St. Laurent , Blaufränkisch two traditional varieties and furthermore new Slovak variety Nitra and Austrian Blauer Wildbacher were carried out measurements of fundamental analytical values. Furthermore,total and individual phenolic compounds,total anthocyanins,optical density at 280 nm (OD 280),total flavanols,reducing power and antiradical activity were determined. The results show that most phenolic compounds and highest antiradical activity has the Austrian variety Blauer Wildbacher which was in sensory evaluation in last place. From Czech varieties it was Cerason and Laurot . In the sensory evaluation landed the best variety Blaufrä nkisch . Very good results then reached a variety Lauroť as in 2008. Due its higher resistance to fungal diseases,health benefits and good sensory properties appears to be interesting for the production of rosé wines,not only from organic production.
