The Ocean Spray bottle specifically mentions no preservatives, artificial flavors or artificial colors. The Kroger doesn't but I also don't see anything on the label that's significantly different from the Ocean Spray other than corn syrup. They both have "natural flavors" added, which could mean anything but other than that there isn't anything in the Kroger label that hints of added chemicals. That's what's so annoying about it.
I don't really have the room to make or store 5 gallons of wine at a time plus I couldn't drink it fast enough. The reason I started to make my own is because I wanted 1 glass per night before bedtime and the least expensive commercial wine I could find came in a 5 liter box for around $15, so it was around $15/month versus less than $5 if I make it myself. If I have a gallon in the fridge and a gallon being made that should keep me stocked up quite nicely.
