I am brewing a extract/grain oatmeal stout and I pitched the yeast 24hrs ago
and there are no signs of fermentation at all. I mashed the grains at 155
degrees for 30 mins in 2 gallons of water then added the extract and boiled
for 60 mins and added the hops the min boiling started. I cooled the pot in
a ice bath in my sink for 20 mins. added the wort to the carboy with cold
water and pitched the liquid wyeast yeast when the temp was below 80 degrees
and put the carboy in a 75 degree room. I sanitized and the equipment the
only thing that I can think of is that I did not sanitize the plastic water
bottle I used to measure the 2 gallons of water I used to mash the grains.
also I order the ingredients online and got them when we were having some
unusually warm weather in the 80's. did I contaminate the beer by not
sanitizing the plastic bottle? did the warm weather kill the yeast? should I
pitch some more yeast? or am I just being paranoid and should I give it some
more time?      thanks carmine

Did you make a starter? A starter, even if not essential, help to start
fermentation faster and also is a good indication to see how strong is your
yeast. Did you check the expiration date on the yeast? The older it is, the
longer it take to start fermentation so 24 hours lag time is not exeptional.

As for your sanitation, the water you took with the plastic bottle must have
been boiled after the mash and should be Ok. Don't forget that if you miss a
step in your sanitation process it don't mean that you will certainly have
an infected beer, it just mean that you are at risk and it's better to be
safe than be sorry.

And for the temp, it's a bit hot, if you can find a cooler place it would be
better, if you can't you can put your carboy in a little bassin and put a
few inch of water in it. Then wrap a towel around your carboy so that the
towel dip in the water. The evaporation of the water on the wet towel will
cool your carboy temp by a few degree at least.

Re: no fermentation after 24 hrs HELP
In my experience, Wyeast liquid yeasts have a tendency to start rather
slowly.  Wait a day or two, and I'm sure your beer will be fine.

If you make a starter and aerate the wort, it's not unusaual to get
fermentation in as little as a couple hours with Wyeast.  A 2 day lag
would make me a little nervous.

Re: no fermentation after 24 hrs HELP
Yes, it made me nervous too.  Now I only use White Labs liquids, which
always reach visible fermentation in less than 24 hours.

I don't think the OP mentioned using a starter, and my assumption (and
experience) with Wyeast is based on not using one.

Whether Wyeast or Whitelabs, I ALWAYS make a starter and urge others to
also.  I get better, more complete fermentation using a starter.
Remember, the yeast companies are in business to sell you yeast, not to
make sure you make the best beer.  It's to their advantage to make it
sound as easy as possible.  Even if the packs or tubes were fresh, you'd
still not have enough yeast cells to give you an optimal fermentation.
Consider that if they're even a week or 2 old, the viable cell count is
greatly reduced.

Re: no fermentation after 24 hrs HELP
a 24-48 hour lag in visible (key word is "visible") fermentation is not
unheard of using Wyeast, in my experience.  not the rule, but i've seen it.

Happens to me all the time.  My brewing supply store always seems to have
plenty of yeast that is a year old, but hardly any fresh stuff.  With some
patience, the old stuff will usually work, but it takes a kick in the groin
to get it going.  I've had my share of slow starting fermentations.  But not
anymore.  From now on, I am always going to make my own starter.  The smack
pack just doesn't cut it.  The exception would be if I am using a reliable
dry yeast like Nottingham, and even then, I might make a starter, just for
grins.

Re: no fermentation after 24 hrs HELP
I always hate the thought on forgetting to start the STARTER a few days
ahead of time.

But it's on my list of Oh Crap I forgot to.....

This will be fine and I have had no visible fermentation for up to 5 days,
and then a flurry on the 6th.
