I brewed a Belgian Trippel yesterday and pitched the yeast at too high a temp. I used two packets of safale 33 because the yeast expired 10/2011. I woke up this morning and there was quite a bit of krausen and a lot of action going on in the airlock. The fermenter was above 78 degrees so I freaked out and put the beer in the garage where the temp is colder. I just got home from work and there is hardly any bubbling and all the krausen has pretty much dropped. The temp is now between 68 and 70 degrees. Do I need to repitch or just wait it out and do a hydrometer reading this weekend?
