ok so i just made my first lager this past weekend using s-23. I just checked in my fermentation chamber and i still do not see any activity in fermenter. I am used to seeing activity on the top, and i know that lager is bottom fermenting yeast. That being said do you get krausen when using lager yeast? also i know that ale yeast takes about 48 hrs to start bubbling...does lager take longer since fermenting at lower temps?
