Last weekend I brewed my first batch of beer. I ordered the kit back in April because there was a Groupon and stuck the yeast in the fridge until I needed it.
Its been a week and I haven't seen any bubbling in the air lock, so I was thinking the yeast didn't make it. However there is a lot of pressure in the fermenter because when I touch the lid I can feel that there is gas in there, and today I saw that the top was not fully locked in anymore. So now I think that the air lock is just not working.
I went to YouTube and saw a video for the airlock that I have. It turns out I didn't put on all of the pieces. I have a 3 piece airlock (http://www.midwestsupplies.com/airlock-3-piece-type.html) but didn't put the circular lid part on.
Is this a big problem or by putting the top on now everything will be ok? I figured the water was there to prevent the wild yeasts and bacteria from getting in there. Is that a safe assumption?
Is this why I don't see bubbling or is it more likely that the yeast didn't last that long, even though it was in the fridge?
