I brewed a Sweet Stout. I had no problems. I did a full boil and started with 5 gallons of water but after removing the steeping grain bags and through evaporation I lost well over a gallon. So I topped it off to 5g and was careful to pitch the yeast at a room temperature to my wort at around 75 degrees. I shook the crap out of it as I always do then put on the airlock and absolutely nothing has happened. The temp here in Baja is about 70+. This is my 6th brew all of which have been successful. I'm use to blowing the airlock off and having a mess on day 2 and 3. I am considering re-pitching a Hefe liquid yeast tube I have sitting around waiting for my next brew. Am I in big trouble?
