Waiting for fermentation

Aug 02, 2005 4 Replies

How long should I reasonably wait before deciding I killed the yeast by not letting the wort cool enough before I added it? The kit (which I haven't used before) says to pitch the yeast at 21 degrees C I followed instructions by adding cold water to bring the temperature down, but admit it was maybe a degree too high before I got impatient.



Is yeast THAT sensitive? Or could I have mucked it up by not stirring in the cold water properly i.e. perhaps I left the cold water on the top and sprinkled the yeast onto that?



Anyway - at what point do I give up and try pitching more yeast?



TIA..Pete


I've heard of it taking 24 to 36 hours before showing activity. Give it

48 then try again. What style of yeast did you use?

Your temp (if I did my conversion to F is correct) should be ok at approx. 74 degrees F. I usually cool to 70 degrees F, but a couple of degrees one way or the other won't kill it.

Couple of questions:

1) how long has it been? I've waited up to 48-72 hours before seeing noticeable fermentation.

2) did you thoroughly sanitize (not sterilize) and rinse everything with boiling hot water before using?

3) did you aerate the wort before adding the yeast by splashing/stirring/whisking as you added the colder water?

4) dry or liquid yeast? with or without a starter?

Making sure you have well oxygenated the wort, and preparing a yeast starter, I have found, really help to promote vigorous fermentation. Without a starter, I've found dry yeast may take a little longer to get going.

I was obviously way too impatient - I'm a bit of a newbie with this brewing lark.

I posted after 12 hours. Now we're 24 hours in and everything has sprung magically to life!

I guess atleast this thread might be of use to other panickers....

I've been through the same quandry - probably everyone has - and decided to 'just let it sit' - well, a week later, that bitch was bubbling so hard I was worried about it blowing out the trap water ! :-)

Do make sure you don't have any air leaks in the container, or you won't get to watch the yeasts fart :-)
