Brewed a European Pilsner last night and it's been fermenting for about 12hrs. I looked at it in the swamp cooler and there seems to be little to no fermentation in the airlock. I brewed this extract kit after it's been in a cabinet for about 3 month, used dry yeast, wondering if I should dump it already or wait??

Wait. Airlock bubbling isn't a very accurate indicator of activity in the wort. The first phase of yeast growth involves very little CO2 production as the yeasts are in rapid growth mode to take advantage of the malt sugar food source. Right now, the yeast is consuming oxygen in the wort and multiplying rapidly. It can take as long as 72 hours or more for the yeast to really get going. When they do, they'll: Eat sugar, pee alcohol and fart out CO2. This is when you'll see your bubbler begin to kick in.

Right now, wait. If you don't see airlock activity after three or four days, you can pitch another packet of yeast in the beer. Check the expiration dates on your yeasts.

I knew it was an older kit but figured what the hell might as well try brewing! I'll give it a few days and see. If not, just gives me another excuse with the wife to brew more .

Are you fermenting in a bucket or a carboy? If you're in a bucket, the lid may not seal completely leaving you with no airlock activity but a beer that's fermenting fine. Gravity readings are the only way to be sure.

It's in a carboy, my initial gravity was suppose to be 1.045 and after boiling and cooled wort was 1.043 so not to far off. Just not sure if the yeast was still good after 3 months of sitting in a cabinet. The airlock is bubbling but not a vigorous fermentation like I was hoping for. Should I pitch more yeast?

I look forward to a slow ferment because its the violent ferments that give the off flavors. If my airlock ever bubbles more than a small bubble per second I worry.

The thermometer on my glass carboy says 60 degrees.

a lager at 60 degrees is probably at the very highest limit for most lager yeasts.
