Potassium metabisulfite

Composition: Potassium metabisulfite.

Use: disinfection, storage of foods and beverages.

Package: 50 g

Advice and information:

Potassium metabisulfite is used as a disinfectant, for cleaning of vessels for wine and spirits, of vessels for foods and beverages and storage spaces.

It has a strong antibacterial action. It has a suppressive action on the development of bacteria, yeast, molds and fungi. It is added during harvest and the storage of grapes before processing, to stop or/and suppress unwanted development of microorganisms. During crushing it is added in doses from 1 to 2 g/l. По време на меленето се добавя в дози от 12 гр до 24 гр за 100 кг ронкано грозде (каша).

Potassium metabisulfite also is an antioxidant. It protects the grapes, fruit, juices, wine and fruit juices from the damaging action of oxygen. In this way protecting from browning and loss of the natural aromas of the drinks.

Sulfurous acid is highly volatile - with time it "flies out"  from the wine or interacts with its enemies - microorganisms and air. It is important to add it periodically.

The same is valid for the potassium metabisulfite.

To stop the process of pickling vegetables -  12 g/ 70 l for normal fermentations; 24 g/ 70 l if there is ropiness or gelling, then it is advisable to combine with potassium sorbate in doses from 0.05 g/l to 0.5 g/l.

For the storage of fruit / grapes - sprinkle on and around the storage vessels (baskets, barrels, cask or other).

During grape crushing - 12 g/ 100 kg for healthy grapes; 18 g/ 100 kg for moderately damaged grapes; 24 g/ 100 kg for badly damaged and contaminated grapes.

After the end of alcoholic fermentation - 12 g/ 100l for healthy wine with no problems; 18 g/ 100l for wine that changes colour; 24 g/100 l for wine undergoing acetic fermentation / spoilage or prone to. 

During racking or wine transfers - 6 g/ 100 l 1 day before the operation.

Periodical additions - when the weather is warmer (above10-15°C), sulfurous acid easily "flies out" from the wine and it is necessary to at least once monthly add 6 g/ 100 l without stirring. for higher temperatures it is obligatory to move the wine somewhere cooler and to add a new dose of 18 g/100 l.

Safety precautions:

Potassium metabisulfite is found in many foods and beverages in one from or another.

The World Health Organization advises limited consumption of such foods and beverages with a maximum daily dose of sulfur based compounds 0.7 mg/kg weight.

Sulfurous acid is highly volatile, with strong pungent and suffocant smell. Калиевият метабисулфит също отделя такава при смесване с вода и други течнсоти.
