Is four days too long to leave a starter on the stir plate. I started it yesterday afternoon and have to go out of town Tuesday and Wednesday. Can I leave it spinning till I get back home Wednesday afternoon and then cold crash it, I’m brewing Saturday.
Four days is fine. However, I would cold crash it before leaving to allow more time for the yeast to flocc out.
If I cold crash before I leave that only gives me about 36 hrs of fermentation, is that gonna be enough?
My SOP is to prepare a starter the night before brewing and then pitch in ~24 hours.
According to this microbiologist from Wyeast, cell growth should typically max out in 18-24 hours: http://www.youtube.com/watch?v=ng0Ib7n4DIA. No reason to go any longer. In fact he suggests that it could be harmful to go longer.
Ok thanks for the info. Into the fridge before I leave tomorrow.
