Last Sunday, I brewed the Northy 12 Quadrupel Belgian Ale with the Extract Kit from Northern Brewer: Northy 12 Belgian Quad Extract Beer Recipe Kit
I am fermenting in a plastic bucket (bottling bucket with spigot
actually). Using Safbrew Be-256 dry yeast. 2 packs, hydrated. Using a
Thermograph stick-on thermometer for temp readings.
Now, I am a little worried about the state of my fermentation, 48 hours
in. The progress has been as follows: (room temperature has been 65-67F
at all times)
Pitched the wort at 68F. Hydrated the dry yeast. Liquid yeast temp was 75F.
After 6 hours, temperature in the fermenter was 66F ). Decent bubbling in the airlock (1 bubble every 2-3 seconds)
After 18 hrs, temp was at 65F. Good airlock activity, about 2 bubbles per second.
After 24 hours, fermentation went crazy. Wort got into the airlock.
Airlock stayed in place. Temperature unknown. (I was at work, the wife
told me about the “incident”)
After 30 hours, airlock was full of wort, temperature was now at 74F.
Bubbling was slow again, at about 1 bubble per 3 seconds. I cleaned out
the airlock, re-sanitzed and put it back in. Sloshed the bucket around a
bit with cleaning. After putting the airlock back, no more bubbling
After 44 hours, temp at 74F, no airlock activity.
Now I am a little worried that the fermentation was so violent and
sudden after 24 hrs, but after 30 hours, everything seemed to slow down /
stop significantly. I have heard airlock activity is not a good
indicator of fermentation activity, but still… From violent to nothing
over the course of 6 hours is a bit strange?
Did I do anything wrong? Did moving the bucket around while cleaning harm the fermentation?
I have now put the fermenter in a water bath (evaporation cooling) at
67F in order to get the temperature down a bit. Ideal temperature for
this yeast is 59-68 F.
I pitched at the warmer end of the yeast temperature range, but
temperatures seemed good at first. Is it a good idea to try and cool the
fermenter down now to under 70F?
Any advice would be appreciated! Thank you!
