I just made a yeast starter for my upcoming brew and I realize the bag I was using for DME was pushing a year old and hasn't been through prime storing conditions. It got mixed in with my other stuff somehow and I realize I used it. The DME seems fine, no visible problems or anything. It also smelled fine when boiling the starter.
I was wondering if there is any concern with using this yeast starter I just made? I know DME doesn't stay fresh for eternity or anything, but I am also only using this as a starter, not a base malt for an extract brew. What are your thoughts, should I scratch the starter or should I go ahead? Thanks!
