Inexpensive drinkin' wine.

[TN.Frank]

I'm making some inexpensive general propose drinkin' wine and wonder how long I need to ferment it.
Basically it's just 100% Grape Juice concentrate cut with 2 cans of water instead of 3 with a cup of sugar added and a dash of Baker's Yeast to ferment it. I'm fermenting in a 4L glass wine bottle with my homemade air lock system(hose from the lid into a small glass of water). I'd like to got for 10-12% alcohol and I know that Baker's Yeast normally tends to die off at about 14%. I just wonder how many days I should let it ferment before I put it into the fridge and put the yeast to sleep and let it settle on the bottom of the bottle before I pour it off into another container for storage and drinking? Would 4 days be enough, maybe 5, should I just wait until I don't see the Yeast working anymore? Anyway, not wanting to make a premium drinking wine here, just something cheap and fun to drink. Thanks.
