Default pitched the yeast when it was way too hot

I brewed my first batch last night and threw it in the primary around 2300 hours. I'm pretty sure I pitched the yeast when it was way too hot. Tried to cool it down as much as I could, but thought for some reason that it was more important to get it in there quick than get it in there cold. I'm guessing it was 95F-105F when I pitched and after having sat overnight I'm thinking its still in the 80Fs, because it only feels slightly warm but still not registering on the thermometer stuck to the side which only goes up to 78 I think.

Also, I have read when making an Amber Ale to stir and to NOT stir the yeast in. I thoroughly stirred it and it was pretty warm.

And this morning I noticed the water in the airlock had gone down by about half, which I guess means its in the wort.

Do you have a big cooler or trash can or even the bath tub where you can place the fermenter and add some cool water and even some frozen water bottles? If not, at least place a damp towel over the fermenter and blow a fan on it.

You already know this- next time bring your wort down to 70 degrees as quickly as you can (ice bath in the sink works great) and then put the wort in the fermenter and then pitch the yeast.

Wait for about 3 days before you worry too much. You probably didn't kill the yeast, unless it was over 100 degrees.

Ok, I just added more water to the airlock and it stayed for about 15 seconds then went inside the bucket. I dunno what to do, but I have to leave for work so hopefully it'll be alright.

EDIT: Just read your response Yooper. I'll throw and towel and fan on it before I run out the door.

Try using a really long blow off tube as large a diameter as you have this will give you a little buffer before anything is sucked into the fermentor. I'ts happening because hot air takes up more space than cold air as everything cools its going to draw in air.

Yep, that's the science behind it. Since the wort has to cool, it'll draw in whatever air it can. Since it's sealed, it'll draw it in through the airlock. (Another reason to cool it before it goes in the fermenter, I guess).

Home on lunch break, just checked the fermentator, temp is down to 76F. Thanks for the towel and fan idea, worked like a charm. Saw some bubbles come up through the airlock too, which is a good sign I guess. Since it was so hot when I pitched the yeast, should I let it sit in the primary longer?

If you have fermentation activity, congratulations! I was worried with the original post. In the future, get your wort dow to, at least, 85F for ale yeasts (lower for lagers).

Leave it in the primary until it's done. Until it's done.

Further comments (sounds like you are fine for now):

If you don't put too much fluid (I use cheap vodka) in the airlock, it won't backsuck fluid, though that depends a bit on the design of the airlock.

You can simply leave it to cool overnight and pitch in the morning, if need be - it's not ideal, but is more ideal than pitching too warm.

What is optimal for most Lager yeasts? I know 70 is the top, and actually too high.

I noticed Irish said he spilled some of the water from his airlock into the wort. I did the same thing and I always put a little bit of the cleaning solution in my airlock (will start using cheap vodka) , because I was told water won’t work. Anyway, will that little bit of solution kill my beer and or make anyone that drinks it sick?
