I am sure I am being paranoid, but this is my 3rd starter and have never seen this before. After cold crashing for 2 days, I have a bunch of bubbles grouped together on the surface and some white floaties. I would hate to infect my beer with this starter so I need some reassurance that it is ok, or advice to toss it and start again. This starter was made from washed yeast that I have successfully used in the past, but last time the surface was clear of bubbles which is why I am unsure. Everything was sanitized with Starsan, but this was my first time using a stirplate.
Thoughts?
