Hi everyone...I am new to brewing and new to this forum. Anybody have this experience: I am brewing a coopers Pilsner using a lager yeast and it took over a week before there was ANY activity of any sort. I think it may have been too warm because I began to notice some bubble-action as soon as I began to cool the beer..and even more when I moved it into my unheated cellar. Is this a common problem for a pilsner?
