I have an interesting thing happening with my latest batch. I'm using the 4th generation of 1056, so I'm assuming it has been... compromised...
The yeast was harvested in February, so I made a starter with it, and there seemed to be some activity. When I added it to the batch, nothing happened for the first 24 hours, and then I noticed some small activity just after that. At about 30 hours, there was clearly some activity. The next day (this morning) there is definite activity, but it has a very strange (although not altogether terrible) smell. Kind of like spinach, canned peas, and a little cheesy, but not like death or feces. I also noticed a bit of pellicle forming, as you can see in the photos. Should I keep it around and see what happens or am I entering the danger zone?
