Need some help from my fellow home brewers. I started my Oktoberfest beer 3 days ago and I still have zero airlock activity. Everything I've read says to be patient. I pitched my wyeast octocberfest yeast at 74 degrees into a well aerated wort. Got a 1.062 SG. Started to get some activity on my way home to get into my keezer to lager it. I've have my keezer temp at 45 degrees. The wort temp is still in the fifties and slowly decreasing. I've read to use a starter as well along with the yeast but haven't experimented with that yet. Made the same recipe last year and it came out great. But I'm not really sure when I started to see any activity. I'm using the Ayinger Oktoberfest recipe out of the clone brews book and it says the lager temp ranges between 42 and 52 degrees. What do you guys think I should do?
