Had an emergency come up just now and I’ll have to delay my brew until tomorrow. I already activated my smack-pack yeast cells. Do I have time, or should I just plan on buying a new pack?
You can put the naughty yeast you spanked into the fridge. Pull the pack out a few hours before brewing.
Or, leave it out. It will then be ready for sure. If I remember I will smack mine a day before making my stater.
You are fine either way. Yeast can be delicate but not that delicate. If they couldn’t handle an extra day at room temperature I don’t think beer would even exsist!
