IDEAL USE:PROTECTION FROM FILM YEAST IN UNTOPPED TANKS.
- These anti-flor tablets consist of an inert pure-paraffin support in which allyl isosulphocyanate, a natural form of mustard oil has been dissolved. Mustard oil is a volatile substance with high antiseptic properties especially with regard toaerobic microorganisms.
- Steryl anti-flor tablets are made with the most up-to-date techniques using fully automated systems, which guarantee consistent quality.
- 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.
- Use one or two tablets of the adequate size, and replace it every 15 days.
