so i brewed a porter on the 8th...4 days of active fermentation, but the SOB is only down to 1.004-6! i'm drinking cider, but want some beer for the vitamins. anyone know if i should try an experiment, and strap a vibrator to the fermenter to "excite" the yeast and get it done quicker? at this rate probably be ready to cold crash for carbing until day after tommorrow!
