BlowOff Tube

After 5 days of no fermentation (at all) confirmed by SG (1.069) reading the same as before I pitch the yeast post boil, I re-pitched a batch of the same variety of yeast last night. This morning (9 hrs later) I had massive fermentation and slight blow off through my airlock. When I returned from work (another 10 hrs) my airlock had blown clear off and yeast splattered my ceiling and walls

So I developed a simple blow off tube to fix the problem. My concern is this, though there is still steady activity, I am worried that the fermentation process will be cut short because of the blow off and subsequent lost yeast. Would pitching yeast to the 2ndary ferment be necessary?

I would wait and see what happens with the gravity. If you hit your FG after a week or 2... I would leave well enough alone. Also, are you sure you are seeing yeast and not just other trub?

I had a very active fermentation last month and dumped quarts of yeast slurry from my blow off container over the course of a few days. The brew had no problems finishing off or attenuating. One of the things the yeast does early on is reproduce, I'm sure they are making enough baby yeasties to replace any lost through the blow off.

I would not worry about it.

Earwig & D0ug,

Thanks for your responses, I will standby.

Thanks!
