The microorganisms responsible for the formation of white film on the surface of wines stored in partially full containers, belong to the specie Pichia, Hansenula and Candida.
These are yeasts with a prevalently oxidative metabolism and almost free from fermentative activity. In addition to this alteration, a loss of alcoholic content takes place as well as the formation of acetaldehyde, which gives a vinegary smell to the contaminated wines.
By floating on the surface of the liquid, Steryl tablets slowly release the allyl isosulphocyanate, which sterilizes the air above it.
As a result, the development of the film is inhibited together with other oxidation related bacterial and enzymatic surface alterations.
Steryl substitutes stopper plugs and the practice of Vaseline oil, which is now forbidden.
