As a new home winemaker, I am just wondering if this can improve a cheap kit. Anyone has such experience? If it works, what is the dose. Say, I have a 7L version red wine kit, such as Cab Sov. with Welch's concentrate available from grocery store.
Or I can add 1 gal of Welch' juice instead of water to make up to 6 gal.
