Rosé wines has gained a great popularity not only in Czech Republic but also elsewhere in the world. Rosé are produced mostly from traditional varieties such as 'Pinot Noir', 'Blaufrankisch' (Lemberger), 'Zweigeltrebe', 'Merlot' and 'Cabernet Sauvignon'. Entirely new act play rosé wines made from blue Czech interspecific grape varieties, such as 'Cerason' or 'Laurot'. For samples of wines (concrete 'Laurot', 'Cerason', 'Kofranka', 'Pinot noir', 'Merlot' and 'Blaufrankisch') are normally carried out measurements of fundamental analytical values. Furthermore, spectrophotometric measurements were carried out - determination of total phenols, total anthocyanins and the optical density at 280 nm (OD280), total flavanols, reducing power and antiradical activity. The results show that most phenolic compounds and highest antiradical activity has the variety 'Laurot'. This variety has besides ideal pink color for rosé wine similarly as 'Blaufränkisch' variety. The new interspecific varieties were higher antiradical activity and therefore health benefits. When choosing a suitable technology for its fruitiness, higher acidity and higher resistance to fungal diseases appear to be interesting for the production of rosé wines, not only from organic production.Rosé wines has gained a great popularity not only in Czech Republic but also elsewhere in the world.

A diet regime plays a crucial role in primary and also secondary prevention of chronic diseases such as some types of malignancy, cardiovascular diseases and diabetes. Current dietary guidelines recommend increased intake of fruits and vegetables, which are not only low in calories but also contain plenty of fluids and fibre. They also contain some bioactive substances such as flavanols. Flavanols are mainly contained in cocoa, red wine, black tea and apples. These substances are improving glucose tolerance, decreasing blood pressure, improving endothelial function and they are decreasing thrombocytes adherence. Chocolate can be recommended because of its high cocoa content, which contains not only flavanols but also other bioactive substances such as theobromine, caffeine, lecithin and many others. A research community has paid attention to chocolate from 1990's when first studies appeared that have not only condemned chocolate as a source of obesity and dental caries but also shown that chocolate can have protective qualities. This article summarizes contemporary knowledge of the positive influence of chocolate intake on development of cardiovascular diseases, on blood pr ssure level and on some laboratory markers. We can recommend to our patients to consume the highest quality chocolate possible (dark chocolate with high cocoa content) but we have to add that this chocolate intake must be in line with energy demands. The "appropriate" dosage of chocolate can be estimated according to some published studies and it is approx. 50g/week. [ABSTRACT FROM AUTHOR]
