I am a first time shiner. I had a blow-off this morning, I'm making shine. I use a plastic bucket with a screw-on air tight lid and an airlock. The pressure blew the screw-on lid off. After cleaning up and adding a blow-off hose, I noticed that the mash is no longer bubbling at all. And, that beautiful krausen I had is all but forgotten. Should I re-add yeast?

I used 5 gallons water, 5 pounds of cornmeal and about 10 pounds of sugar. Then I used TURBO CLASSIC YEAST.

What blew out is just the krausen while it has a lot of great yeast in it, there should be plenty left to complete fermentation.

Just a note. Cornmeal needs a cereal mash to expose starches and then enzymes from grain or adding them directly to get fermentable sugars on a mash. If this wasn't done then all that fermented was the 10lb of sugar, so keep that in mind when taking gravity readings.

    To add on, the unconverted corn meal may provide food for contaminations.

  • @DennyConn indeed. But if it's hypothetically being distilled it wouldn't matter much. Sep 13, 2016 at 23:23
  • yes, if that's the purpose. Since this group is about homebrewing I didn't think of that.
