Starter gone bad

I did a starter with California Ale Yeast WLP001 with my stir plate. I had to leave town for several weeks and forgot to transfer it to a sealed container for long term storage.

This was the result: https://imgur.com/a/br0Ju5q

Definitely wouldn’t pitch it. Spend a few bucks and do it again. I had a starter going for 4 days thanks to a delayed brew and it stalled at 1.040. Same yeast strain as well.

I use it so much of this particular yeast. I wanted to just get a whole bunch of it for storage. Unfortunately I only have a 1L beaker so I have to do multiple stages of starters to get what I need.

I believe US-05 is the same strain, you might consider buying a bunch of it and not bothering with starters. Keeps for years in the freezer.

4 days in a starter is too long? Eh?

By day 4 the yeast started to die off based on the cell count I had. Still fermented the beer from 1.072 to 1.040, but I’m thinking the alcohol content in the beer killed off the rest of the weaker yeast?

It goes dormant tho
