This is my second batch of wort. My first went so smoothly I decided to start another in the primary after racking the fisrt over to the carboy. It's been sitting in the primary now for 24hrs and there is no "krausen" forming on the top like my previous batch had done within just a few hours. OG was 1.045 (same as the first) when poured and the temperature has been consistant at 19c-20c (same as the first). There is a thin layer of white foam on the surface which im assuming is the remains of the foam created by pouring the wort and the yeast that was pitched. Also, unlike my fisrt batch there is no temperatrure increse that was caused by the fermenting process, further leading me to believe that there is nothing happening and that something is wrong.
The style of beer is different; The fisrt was a Canadian light beer and this one is a golden blonde ale. I'm not sure if that makes a difference.
UPDATE: It's been about 30 hrs now and the Krausen has magically appeared. There is however a small area where it hasn't formed yet and is about 2" thick everywhere else. I'm assuming this isn't a problem... I'm also assuming, to compensate the late start of the yeast, I should keep it in primary for a little longer then perscribed?
