Well, after almost 36 hours, my pumpkin beer started to show signs of fermentation. Before I went to bed last night, there were N signs. No foam/ krausen, no bubbles in airlock, nothing floating around. It was just sitting there. Put it in the keezer with my other beer in primary (a pale ale), and woke up to about a 1/2 inch krause on top with bubbles in the airlock. I used WLP051 yeast which is known as a slow starter, but I didnt think it would be that low. I dont know if the lower temp is what it wanted, but it seemed to work. Fermenting away at about 65 deg F right now. Hope this helps anyone using this yeast. Be patient, and use a starter if you can.

Just had one take 80 hours to show a krausen or any visual signs of activity. No worries.

72 hours into my first batch. OG was 1.050 and I just checked the gravity...still 1.050.

I did notice a layer of something on the bottom. Is that the yeast or should I go buy more yeast and re-pitch? I used 1187 Ringwood Ale and the smack pack barely inflated.

Stuff on the bottom is probably break material and crud/stuff from the brew/boil.

Mine took over 84 hours to get started and it's rolling now.

Damn, that was my only hope that something was working.

So how long should I wait before I think of getting more yeast?

I think if your gravity hasn't changed after 72 hours you're justified in re-pitching. I'd re-aerate before, too.

Especially if no change in gravity. And probably only if no change in gravity.

Yeah I don't think I aerated enough so I bought some Nottingham dry yeast, sprinkled it on top, stirred it around and shook the fermenter so hopefully it does something now.

A sanitized whisk works really well to froth it up.
