Default **** Fermentation won't start

Any ideas why?

I did my first all grain batch, I forgot to check to see if the starches converted. I held the mash at 150 for 60 minutes, so I would think the starches converted.

My gravity after a 60 minute boil was 1.053 (right on the dot to my recipe). I cooled it as much as I could (between 75 and 80 - ran out of ice). The White Labs WLP001-California Ale sat out for approx 6 hours to come to room temp (80).

The wort was airated while I poured into the carboy plus I shook the hell out of it for a few more minutes. Pitched the yeast. Then airlocked it and placed the carboy in my freezer (temp controlled at 68 degrees). It has been in there since Weds the 4th at around 5 or 6 pm.

Not one bubble!!!

Any ideas why?

Did you make a yeast starter? If not, that could be the reason. I never ever evar use liquid yeast without first making a starter (2-liter, with at least 6oz of extract). I've had liquid yeasts take over 72 hours to start (back before my militant stance on starters)...especially the White Labs vials---I've had some of them never start. The pitching temp was okay. You might not have aerated quite enough, but that's debatable (I urge you to get an aeration or oxygenation kit in the future). So I think it's the lack of starter.

I decided not to make a started cause i am doing half batches (so I can full boil on my stove) and thought the vial would have enough yeasties for 2.81 gallons. This is the first time using White Labs vials (not too happy with them right now), I've used Wyeast (going back to them) in the past and would get fermentation within 8 - 12 hours with the same aeration technique. Planning on buying a oxygenation kit in the future.

So you think I should wait it out or go buy another batch of yeast (Wyeast) and pitch again?

I'd give it three days after pitching. If nothing happens...pitch more. With that batch that took 72 hours to start, I went to the local brewpub on the third day and scored some yeast to repitch---and when I got home that night and pulled back the blanket, it had already started with the original yeast. SO...you never know.

no starter(or yeast cake) with liquid yeast generally takes at least 48 hrs to get going, regardless of the size of the batch.

Interesting. I have never had a problem using liquid yeats wyeast or white labs. I started using starters but lately I have not. I just brewed a Hefe yesturday and pitches a wyeat pack that was not even swollen. She started up within 6 hours. I go with the other guys and give it some time. If no action then pitch more.

I have never had a problem with Wyeast either (8-12 start times), but I happen to go to a different LHS for my supplies and all they carried was White Labs. But this vial of WL is taking fooorrrreeevvveeeerrr

Now on if I use WL I will make a starter. Wyeast I won;t worry about...

When using liquid yeast, check the packaging date of the yeast you are buying and try to buy the freshest yeast you can. Sounds obvious I know, but as those vials and packets sit in the cooler at your LHBS, those yeast are slowly losing viability. I bought a pack of liquid yeast one time and did not check the date. When I finally used it to make my starter, nothing after 2 days . The packaging date was about 6 months prior to when I tried to use it.
