The legislation does not limit the manufacturing plants rigid framework of requirements for quality and intensity of color produced rose wines. Therefore, the range in their color is quite wide, which leads to the use of several technological schemes for the production of this group of wines.
For rosé wines using red grapes with unpainted - Cabernet Sauvignon, Merlot, mattresses other - or with colored juice - Saperavi Dzhalita, Odessa black and pink (Traminer) and white varieties.
The first scheme includes admission to split with destemming only red grapes, red and pink blend of grapes or a mixture of red and white in a certain relation to the subsequent processing "white" method and yields rose wines with low color intensity, close to the white .
According to the second scheme grapes white grapes crushed with the separation of the ridges is taken 60-65 gave wort c 1 ton of grapes, which is fermented on the red squeeze remaining in the fermentation tank after the descent of a young red wine and further treatment is carried out according to the scheme adopted for the red wine. By this method, aromatic, fresh, but lightly colored wine.
The most widely used in practice to get the third scheme preparation rosé wines, carried out by blending red and white wine.
Rosé wines with intense stable color close to red, prepared using technological methods typical for red wines - limited infusion mash, podbrazhivaniya and adjustable heating, and a short maceration of carbon dioxide.
Areas of production and brand of natural pink dry wines
Of Moldova. Very harmonious pink wine with constant typical properties required color intensity is obtained blending technology developed by the institute "Magarach" together with the winemakers of Crimea and Moldova on the basis of a single grape variety.
Kaushanskaya rose varietal is at the same time as blended wine, which is used for the preparation of Merlot grapes with sugar content not less than 17% for whites and not less than 18% for red wine. The white base wine materials merlot grapes processed "and white" way. Wine materials store and process technology white dry wines. Red blended wine materials prepared by the technology that provides maximum extraction of dyes using thermal treatment of pulp. To do this, the more mature merlot grapes with sufficient technological reserve colorants are processed on the production line for red wines. Crushing and mash after separation of the ridges based sulfitated 100-150 mg / kg SO2 and heated to 55-60 ° C in mezgopodogrevatelyah. The heated compressed pulp fractions with separation of the first wort, the wort is cooled to 20-25 ° C using a tubular cooler and fed to the fermentation. Young white and red wine stocks after clarification and removal of yeast treated with CSW or Trilon B, is filtered and stored separately in conditions that preclude their oxidation at a temperature no higher than 16-17oS. Blending and final processing of rose wine is carried out before release. The ratio of white and red wine is taken in the range from 80% to 20% to 90% to 10% depending on the desired color.
Independent type of pink dry natural wines emerged in France, which shows the well-known standards - Bordeaux Rose, Bordeaux Claret, Burgundy Rose and others.
In France, laid the foundations of law and technology developed unique technological schemes of rose wines. One of them involves the processing of grapes on the pink method. The essence of this technology lies in the fact that the grape varieties are processed sufficiently stained with infusion mash on pulp for 6-24 hours, sometimes with podbrazhivaniem, meaning "the red" way, but the resulting wort is cooled immediately and thoroughly defend to remove suspended matter before fermentation. This technology allows you to get a pink wine minimum amount of phenolic substances in the presence of an adequate supply of anthocyanins. However, with further exposure and processing of wine may appear unusual yellow shades of color and dyes tend to precipitate.
Classical technology provides a variety of rosé wines by grape varieties and regions - gray Claret lightly colored varieties of Senso, Grenazh black, Pinot Noir; pink from Cabernet Franc, Mourvedre, Cabernet Sauvignon and red claret - dark pink wines from Merlot, Carignan.
