My Mother gave me an ingredient kit with White Labs liquid White Ale Yeast. However, she didn't realize that the yeast needed to be refrigerated. I put it in the fridge as soon as I opened it but it had been sitting at room temp for about 10 days before it was opened. It came with an ice pack but I'm sure that didn't last too long. Do I need to get new yeast or can this vial be saved? Thanks!
