Fruit wine is, by definition, a beverage made from fruits other than grapes. However, the production of fruit wines does not differ significantly from the production of grape wines (made from the fruits of grapevines). In both cases, the pressed must undergoes alcoholic fermentation. The fundamental difference is that, in the case of grape wines, there is no need to add wine yeast for fermentation, because a sufficient amount of it passes into the must from the surface of the grapes. The surface of other fruits contains considerably less yeast, which is why fermentation is supported by adding pure yeast strains. Furthermore, depending on the properties of the fruit being fermented, it may be necessary to adjust the sweetness and acidity (e.g. by sweetening, diluting or acidifying the must). Once fermentation is complete, the wine is clarified and then aged and bottled. Wine sometimes also requires stabilization to prevent it from becoming cloudy or fermenting again.
Fruits and vegetables are of the greatest value in a balanced diet. Their appropriate use may help prevent so-called lifestyle diseases, including obesity, circulatory system disorders and cancer. However, the availability of fresh fruits and vegetables on the market is seasonal. Therefore, methods of processing them should be used to ensure access to healthy and tasty products throughout the year. Juices and purées naturally contain the most vitamins and minerals, but fermented products such as fruit wines and ciders can also be consumed. It should be noted that the health-promoting components of fruit remain in the wine after the fermentation process is complete. And although alcoholic fermentation also produces compounds that are not beneficial to our bodies in large doses, a glass of wine can safely be enjoyed even several times a week.
According to many researchers, fruit-based alcoholic beverages consumed in moderate amounts, e.g. during a meal with friends, have a positive effect on our physical and mental well-being and slow down the ageing process. Fruit wines are a valuable source of easily absorbed vitamin C and other vitamins, including A, B, H and PP. They also contain significant amounts of minerals, including iron, phosphorus, zinc, copper, selenium, magnesium and calcium. The antioxidants contained in fruit wines neutralize free radicals, which are responsible for cell ageing and the development of cancer. Wine, when consumed in small amounts, naturally, has a positive effect on heart function and digestive processes, lowers blood sugar and cholesterol levels, improves blood flow through the blood vessels and supports the immune system.
