Activated Yeast Pack question

[IvanTheTerrible]

I had my yeast pack refrigerated, so I activated it late afternoon so I can brew in the AM. The package is inflating pretty quickly. Will it explode if I leave it over night? Should I put it back in the fridge?

Thanks,

No, leave it out. It won't explode, but it'll get as tight as can be. You don't want to shock the yeast by taking it out of the fridge, activating it, sticking it back in the fridge, and then taking it out tomorrow. Yeast do NOT like temperature changes. It's fine out until tomorrow when you brew.
