Last night I made 2 yeast starters using 1/2 gallon milk jugs (cleaned +sanitized) and wort of around 1.030-1.040 gravity. I made each started about 1.5 quarts. I also added just a pinch of yeast nutrient. However, I forgot to let the White Labs vials acclimate 3-6 hours prior to pitching, so to gently speed things up, I put them in a cup of luke warm tap water. Maybe 1-2 hrs later I pitched. I've been oxygenating lots, and the temp is probably in the low 70's. Its been 12 hours now and there's absolutely no activity, also I cann see the yeast at the bottom of the jugs. Any Ideas? I need to pitch in maybe 4-5 hours when my Hobgoblin Clone is ready. If the yeast hasn't started yet/ or isn't finished when I need to pitch, can/ should I just pour out most of the wort and toss the yeast in? Don't worry, I AM drinking a homebrew.
