Did second AG last week. Split batch with my son. Used liquid ale yeast (Wyeth, I think). Only variables were that he put his in carboy, mine in plastic bucket and temperature. I put mine in cellar (about 64 degrees) --- after week no fermentation, gravity reading the same.. My son's started fermenting after a day or two. Brought mine upstairs today, swirled it around and bubbling started. What effect does a delayed fermentation have. This has been sitting 6 days , I guess in it's original state from the brew pot since the yeast hasn't done anything. I guess it's like pitching the yeast a week later.
