I am making homemade wine the easy way with juice I pored about a cup out and added 2 cups of sugar and 2 tablespoons of yeast boiled my s shaped air lock and Once I put the carboy and air lock in I filled the air lock with water but only the right side will fill but if i squeeze it i get both sides on max also it won't burp could this be because my juice is to cold? It is kinda cold so I put a towel around it do you think it will burp once it warms up?
