I used the WLP001 and created a 2L starter 2 days before brewing. Due to unforseen events I was unable to brew that weekend. I took the starter and put it in the chest freezer at 39 for 3 weeks now. The Flask has a stopper on top with a 1 way filter.
Ill be brewing this weekend. Do you think this starter can be revived or should I toss it and use a new vial.
