Q: How does Velcorin work?

A: Velcorin penetrates the cell and deactivates enzymes leading to the destruction of micro-organisms.


Q: What factors determine Velcorin effectiveness?

A: At low doses, Velcorin is very cost-effective against yeast and fermentation bacteria.


Q: Do I have to list Velcorin as an ingredient on the label?

A: No, the FDA lists Velcorin as a direct secondary food additive and therefore no labeling is required (21 CFR 101.100). 


Q: How much Velcorin may I use?

A: The TTB allows up to and including 200 ppm of Velcorin in wine.


Q: What is the residual breakdown of Velcorin?

A: After addition to the beverage, DMDC rapidly breaks down into negligible amounts of methanol and carbon dioxide, which are naturally occurring compounds in many beverages such as fruit and vegetable juices and wines. Consequently, it has no effect on the taste, aroma or color of the wine treated.
