I just received an order from an online brew store which included a vial of WLP650 and the best before date on it was 12/08/19. I emailed the company to let them know it was out of date and they replied to say that it should have been reduced but slipped through the net and they would give me a refund. Fair enough. Then got another email to say that actually the best before date is US format and so the best before date is 8th December. If anyone has a pack of White labs could they have a look to confirm that? Not that I think they're being disingenuous, I just wonder how I never noticed that before. That being said, I don't often use White labs and I wonder if they've changed their packaging recently or if their wild yeast/bacteria are packaged differently because the last time I used them the yeast was in a little soft plastic pouch, the 650nis in a hard plastic vial.
