Title says it all. I made a doppelbock (1.076 SG) and normally I have good temp control for my fermentation, such is not the case with this beer. I pitched at about 46 and let it rise to 50 over 30+ hours, it stayed at 50º straight for about 48 hours. This is when i had a problem keeping it steady, at one point in time it went up to 55º and another down to 47º. I know this is terrible for the beer my question is can i fix it? Right now it is still fermenting away at 51º still has plenty of activity after about 8 days. I have on me 2 packs of fresh Barvarian lager yeast. Would it help my situation if I got them started up on a stir plate with some food and them dumped them in the beer to help clean it up?
I know i need a temp controller and its the first thing on my list to get so you can spare me that talk

Thanks for your input guys!
