Default 16 Hours - Still no signs of fermentation

So I brewed a 1.081 OG Weizenbock with WLP300 (Hefeweizen) - based upon the Weizenbock recipe in Jamil's Brewing Classic Styles. MrMalty called for the equivalent of 3 vials. So I had made up my starter as usual, but when I took it out of the fridge to decant, I had every reason to believe I had gotten an infection and was really, really leery about pitching it and ruining a batch. I decided to quickly run to my LHBS and pick up what they had, which was only 2 vials. I oxygenated the wort thoroughly and then dumped the two vials and placed it in my fermentation fridge at 62 (per the recipe).

Well, here we are 16 hours later and I have NO activity. This being the first beer I've done without a starter in a long time, I just don't remember if this is normal or should I be worried. Would anyone possibly recommend increasing the temp to room temp to get the yeast active and then bringing back down to 62?

http://www.homebrewtalk.com/f39/ferm...e-signs-43635/, and by visible signs we don't necessarily mean a bubbling airlock.

16 is less than 72 hours, last I checked. Just give it some more time. because you didn't use a starter, lag time IS expected.

Relax

Thanks, Revvy...I've just had such incredible success with starters and quick, violent fermentation that I just feel incomplete right now...

Just remember how many brewers (usually new) brew beer without making ANY starters, and often pitch only one tube of yeast, and their beer manages to turn out (though prolly not as cleanly as we know is possible.)

You at least pitched two. So you doubled the odds anyway.

Yeah, I second revvy. You'll be just fine. I had a some batches that took 3 days to start going, but once they did, they really took off.

Do you think the lag time has anything to do with the fact that I'm at 62 degrees?

72 hours and NO signs of fermentation. NO bubbling in the airlock or any visible activity in the carboy. I just can't believe that I pitched 2 vials and I've got no signs of anything. Any ideas?

Well, haven't taken one yet...I supposed that is indeed the true indication of fermentation, right? Guess I just answered part of my own question...I'll go check

Just took a gravity - it hasn't budged. I can't imagine what the heck is going on.
