First try at making wine
My first try, I took 35 pounds of red grapes, washed them and ran them through the blender along with 3.5 pounds of sugar. Made just over 4 gallons of juice. Put about 3 gallons of the mix in a stainless steel stock pot with a cheesecloth tied on, and put the other gallon in two plastic bottles. The plastic bottles have no yeast added, just whatever wild yeast was on the grapes. I did not sterilize the juice. The big steel pot had about a tablespoon of Red Star bread baking yeast added to it.
What's the worst that could happen?
