Bought some WLP 400 a few weeks ago and wasn't able to get ingredients until yesterday due to all the closings. I made a started starter yesterday with some light DME that I had (and had made other starters recently with) and got out the WLP 400 from the fridge and it was a dark brown color. It looked off compared to what yeast normally looks like out of the package. Is this a sign of anything. The date on the package was 07/22/20 so it wasn't like it was old yeast. Thanks.
