Default Did I KILL my yeast?

Brewed my second batch of beer yesterday...

Figured I'd rehydrate the yeast this time since I didn't bother on my first batch. Well, I read the instructions wrong and used BOILING water instead of warm water... It's been 12 hours and I see no activity... No spare yeast on hand... Suggestions?

If you used boiling water - definetly. Go get another packet and sprinkle on top of the wort.

MURDERER!!!!!!!!!

But seriously yeast are wise and probably anticipated you doing that, so there were some survivors. These survivors should reproduce and make plenty more. Someone wiser than me has said RDWHAHB, I would take a gravity reading and another in a few days if there is no airlock activity. If there is no gravity change or activity I would just pitch another batch of yeast.....

If he used boiling water to rehydrate his yeast, it was 112 degrees too warm to correctly do the job.

Yep, you fried them little suckers like a boiled lobster! Go get another packet and rehydrate with water that's approx 80F.

Would there be any problem of waiting till Friday to pitch more yeast? (Can't really get to the beer supply store till then)

Also, the "beer supply store" is actualy a wine shop that has very limited supplies and 0 knowledge on beer supplies. What type of yeast should I be looking for? I was brewing the Imperial Blonde Ale from a Brewers Best Kit.

As I understand it, every hour that goes by unpitched is an hour that your wort is susceptible to being overtaken by other organisms or wild yeast (which are undoubtedly in there now).

Having said that, you gotta do what you can do, I suppose.... It'll probably be fine.
