I Brewed Revvy's Leffe clone recipe using WLP530 14 days ago. Made a 1.5 liter starter and fermented at 64* for 7 days. Days 2-4 were pretty active with krausen going into the airlock. Things seemed to calm down so I ramped to 68* on days 8 and 9. Things definetly slowed down with maybe 1 airlock bubble every 30 seconds and no visible movement inside the carboy. Last night I checked on it and the ferment was full force, almost needing a blow off tube again. Looking inside I could see the violent convection of the ferment. What gives? Could it have been the high mash temp at 158*?
