My first time using this yeast and it is my 2nd batch. just 2.5gallon but it split it into 1gallon and 2gallon jugs. started the yeast then pitched late monday night, next morning it was going crazy. wednesday evening the 1gallon jug is bubbling slowly about once every 13seconds. the 2gallon i barely see any bubbling. is it fermented out or is there something wrong with it? I am new at brewing. please comment
