I made my starter last Friday night (19th) with the intention of brewing on Sunday afternoon. Life happened and something came up, so brew day was postponed. Kept it spinning on the stir plate until Monday evening and put the flask in the fridge. Tonight, I decanted from 1700ml to 800 and put back in fridge. If I can't brew until Saturday, is my starter ruined? The flask is still covered with foil. Are there any precautions/steps I need to take different from what I would normally do? I've always pitched directly from stir plate to fermentor in the past. I really don't want to waste $15 worth of yeast, but would like to know with enough time to get another starter going if necessary. Thanks.
