I found a goon bag (a wine cask) behind my bookshelf. Since I have no alcohol, and no money to buy any, I decided to drink it. It tastes weird. It's over sweet and kind of vinegary. I don't understand how a goon bag could become oxidised. Maybe it was bad when it was first put in the bag? Anyway, I'm going to drink it. Any tips? Do you think bacteria in it can make me sick?
