In StockDet er både uprofessionelt og ukorrekt af bruge Kalium-meta-bi-sulfit (KMS) eller andre former for Kaliumsulfit til konservering af færdige vine og for så vidt også uhensigtsmæssig at bruge KMS ved forebyggelse af oxidation af most og under fermentering. Årsagen er at tilførte Kalium-ioner jo medfører nydannelse af vinsten i flaskerne efter tapning (kun druevine med vinsyre) , da udfældningen af vinsten er en langsommelig proces.
Derfor anbefaler Pumpton College i Brighton, Comittee Interprofessionel du Vin de Champagne (CIVC) at bruge Ammoniumbisulfit, som fås i en lang række forskellige koncentrationer i vandig opløsning, klar til direkte tilsætning.

Maximum legal dose: conform to the current legislation.
OENOLOGICAL APPLICATIONS
AMMONIUM BISULFITE A 150 g/L may be used:
During the harvest:
• On must: In the must collecting tank to prevent oxidase taint and any microbial contamination.
• On red wines: When vatting or whilst pressing, to extract and stabilise colouring matter.
AMMONIUM BISULFITE A 150 g/L has the following properties:
• It is a selection factor for yeast since it limits the growth of undesirable yeasts.
• With its antioxidant action, it plays a role in the prevention of oxidase taint, contamination (flat taste) and Maderisation.
• It helps extract colour by encouraging the breakdown of the anthocyanins contained in the grape skins. • It helps stabilise colour with red wines.

Homogenize properly after addition in wine or must.
Avoid contact with metallic items (iron, copper or aluminium).

Sulphurous solution, stable and odourless, intended for sulphiting of must, without addition of potassium but providing a source of nitrogen.
Sulphiting agent in a concentrated solution (63% ammonium bisulphite), which can produce sulphur dioxide without enriching the medium with potassium. Specific for the initial fermentation phases.
Ammonium bisulphite solution free from cation minerals that could be detrimental to the stability of wines. Its easy to use solution state facilitates its application in fermentation, especially if used in automatic in-line dosing systems.
