So I am brewing a weihenstephaner weisse clone (first brew ever) and after pitching the yeast (white labs 300) it took about 36 hours to show any airlock activity. The bubbling, however, lasted for less than a day. Is this okay? I dont want to take a hydrometer reading yet because I doubt the fermentation is done and i don't want to disturb the process but is it possible that it is stuck? I should say that it took me close to 2 hours to bring the wort under 80 (covered most of the time). Any advise?
