i brewed the breakwater pale ale recipe from northern brewer saturday. i live in the desert, so it's hot here, even with my air conditioning on. i pitched the yeast (safale us-o5 ale yeast) at about 76 degrees. optimum high temp is 75. the room i have my carboy in is cool (about 74-75) but nothing was happening. i did the ol water tub and towel wrap, and it's been down at 68 since. however, there are only tiny bubbles, no blow off. it's been about four days so i doubt any active fermentation will take off now. should i pitch more yeast? if so, how much? thoughts? ...and thanks!
