In wine, the fortress which is below 15%, in the ambient temperature above 15 ° C, appears wine mold. For its development a particularly favorable flow of air. This grayish folded film destroys the wine, turning it into carbon dioxide and water. The film can be removed.
Take the rubber hose, put one end in a container of wine below the film. Through the other end gently pour a "healthy" wine. A layer of film will start to climb and, reaching the edge will come along with wine. The remains of the film remove the first, just a clean rag, then with a cloth soaked in a container of hot water and baking soda.
Clouding is another common defect of the wine. He has several reasons. This may be a consequence of delayed transfusion drink after active fermentation. Thus settled the grounds, if wine fixed low content of alcohol, can even rot. Turbidity in wine may also appear as if it is not vibratile.
How to get rid of the dregs? Filter the wine through a cloth filter. Use a cone-shaped bag, mounted on spacious dishes for wine. The best fabric for it - a canvas, calico or bumaspa. If you use a bag of white flannel, then turn the hairy texture on the outside.
If you clean the wine from the thin dregs, use asbestos. Vsypte in an enamel pan a handful of asbestos, pour into it the wine and stir. Skip the slurry through the bag. Repeat until, while on the walls of the bag can not be formed thick asbestos layer and flowing through it, the wine will become quite clear.
Wine filtration on an industrial scale is a complex stepwise process in which the wine is cleared from mechanical sediment, turbidity, sediment, yeast, cream of Tartar, microorganisms and other substances with the help of special equipment.

It uses the filter elements of the so-called cartridge type (filter cartridges). They are used in the preparation of the wine, and to filter the surrounding technological environment (water, air, etc.).

The so-called membrane filtration is used at the finishing operations for the preparation of wine.
