You will need
  • - canvas bag;
  • - rubber hose;
  • - asbestos.
In the fault, fortress of which is lower than 15%, appears in a room with a temperature above 15 ° C wine mold. For its development, air flow is especially favorable. This grayish folded film destroys wine, turning it into carbon dioxide and water. You can remove the film like this.
Take the rubber hose, lower one end of it into the container with wine below the film. Carefully pour “healthy” wine through the other end. The film layer will begin to rise and, reaching the edge, will splash out along with the wine. First remove the film with a clean cloth, then with a cloth dampened in a container with hot water and food soda .
Clouding is another common wine defect. He has several reasons. This may be the result of untimely transfusion of drink after active fermentation . At the same time, the settled thick, if the wine is fixed with a low alcohol content, can even rot. Turbidity in the wine may also appear if it is not sufficiently degraded.
How to get rid of turbidity? Filter the wine through a cloth filter. To do this, use a cone-shaped bag, mounted above a spacious dish for wine. The best fabric for him is canvas, calico or boomazeya. If you are going to use a bag made of white flannel, turn it out with a furry texture.
If you clean the wine of thin turbidity, use asbestos. Pour a handful of asbestos into the enameled pan, pour the wine into it, mix. Pass the suspension through the bag. Repeat the procedure until a dense asbestos layer forms on the walls of the bag and the wine flowing through it becomes completely transparent.
Filtration of wine on an industrial scale is a complex step-by-step process in which the wine material is cleaned of mechanical suspensions, turbidity, yeast sediment , tartar, microorganisms and other substances using special equipment. It uses filter elements of the so-called cartridge type (filter cartridges). They are used in the preparation of wine material itself, and for filtering the surrounding technological environment (water, air, etc.). membrane filtration is used in finishing operations for the preparation of wine.
