I had some Wyeast 2487-PC Hella Bock yeast that was nearing its "best buy" date.
I have a maibock planned but wont get to it for at least another couple weeks.
I made a starter and its been cold crashing in my fridge for a few days now.
leave it in the flask with the foam stopper?
Put some star san foil on the flask instead of the stopper with a rubber band around it?
Boil a mason jar with water, let the water cool, decant the starter, mix with the sterile water & transfer to the mason jar for storage until im ready to do the starter a couple days before brew?
I was leaning towards the last option but thought i might get a couple other opinions.
