Not sure if that's what was in the smack pack originally or what propagated. I'll take a hydrometer reading tonight, but would it be out of the ordinary to not see an active, foamy fermentation?
The only reason I posted on this was that I was totally amazed that there were some live cells in the pack after so long. The colony is now 8 liters and resting in the botom of the vessel. I have tried three other yeasts after 2 years, and they are dead.
With very small build-ups from a slant etc, 10ml, 50ml, 500ml etc little visible activity is expected, a few tiny bubbles perhaps. Afterward, very visible signs are expected.
There is no doubt the yeast resting now is the original strain. IT is one tough yeast!
When you boost to one liter, you will know for sure, no missing the activity in the flask. cheers.......
PS. The little pouches that are supposed to be "smacked" seem to be of the proper wort type for the strain. Interesting. to me anyway. I'm easily amused......
