Hi..,

Recently I tried to make wine by combining mashed grapes, simple syrup 1/2 cup sugar and 5 cups of water. I put all in a 1 gallon jug and fastened a rubber glove over the jar. After one week, the glove is now completely inflated. I did not add any yeast.

Do you have to use yeast to make wine?

I see what appears to be mold on top of the mashed grapes. Does that mean I've lost the batch?

Mold or no, have I made an inadvertant wine bomb?

Thank you..
