I would say a wine taste is something fruity with a moderate amount of alcohol.
The gallon glass jug and air lock that I bought on amazon should be arriving tomorrow so I'll probably make another batch in the following days.
I'm gonna use 100% juice concentrate as oppose to the added sugar ones with high fructose corn syrup. In 100% juice concentrate there is no sugar added and is simply the grape's natural sugars, however half of the vitamins are lost in the concentration process.
For 1 gallon, it costs 4-5 dollars for the ingredients which comes out to around a cost of 1 dollar for a standard size wine bottle(750ml).
