doing an ipa and it's going 72 hours(68 to be exact) and still no signs of fermenting. i noticed the temperature where i had the fermenter stored was a 61 degrees. checked the hydrometer readings and it was actually higher than when i first took them before pitching the yeast(maybe i just didnt get an accurate first reading at the time?). i used safale 05 and rehydrated, unless during the rehydration it sat out too long, but i don't think it did(maybe half hour). unfortunately it's easter and homebrews stores are closed today around here.
