dpt222 said:I am just starting out as well, but from what I know so far as long as you pitched the yeast at a reasonable temp 70-90 degrees and never above 120 you should wait a bit longer before you worry. Plus, you cannot always rely on the airlock to tell you that fermentation has started or finished as I recently read on this forum that plenty of people have missed fermentation from a leaky airlock.
Will just pitching yeast at about 90, as long as it's kept at normal temp during fermentation (e.g. 60-75 for top-fermenters), create off flavors? Instructions for my True Brew kit said to pitch below 90, but I know that Papazian says to pitch between 68-78.You should pitch yeast between 65 and 75, better yet closer to 70. Anything higher is bad for the yeast and will give you 'off' flavors in your beer. Up over 100F is way too hot.
