Making wine need help

[DrunkAsASkunk]

I'm making a dry french red wine (Cabernet Sauvignon)and i prefer a medium dry wine, the sg on the wine right now is .994 and is dry enough for this cat...please tell me what i can do to stop fermentaion. I realize that i could put the wine in a cold place,but is there any other options such as a chemical? What does sodium metabisulphite and potassium sorbate do?...please tell me what aditive and how to add this to my wine. thanks...this wine is from a wine kit...not a pro yet [img]http://www.wines.com/ubb2/smile.gif[/img]
