should i repitch?
« on: June 20, 2012, 05:33:49 PM »
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!

Did you rehydrate your yeast, or make a starter? How old was the yeast packet? Did you take a gravity reading before pitching?  If you did, take another reading and see if it has changed.  I've had a few brews that didn't look like they took off, but were fermenting away just the same. IMHO, adding more yeast won't hurt anything, but without pinpointing the cause, may not do anything either. Just a word of advise: invest in a chest freezer or fridge for your temp control. It has made a world of difference for me. 8)

check to see if lid/cap/bung is secure, stir with a sterile spoon or shake.

If you pitched at 76 it would actually create a real vigorous ferment.  I guess based on your OG though.  All of my brews are typically over 1.060 so I usually have blowoff with US-05, unless I ferment really cold.

If you're gonna repitch at this point, rehydrate it.  The old towel and cold water trick is good in a pinch.  But, you should really think about a more consistent fermentation chamber.  You can do it cheaper than you think, if you have room for an extra fridge.

I agree with taking a SG reading before pitching.

+1 to taking a gravity reading/having a look in the fermenter before doing anything.  I can't tell you how many times I had no activity because my lid was not snapped all the way on and I opened the bucket to see it was fermenting away.....

Unless it's on carpet, I would give it a gentle swirl after reclosing the lid to push out any O2 that got in there.

thanks guys, i just checked the gravity, it went from OG of 1.038 and is now at 1.017. so would you let it ride? i appreciate the help! still pretty new to this!

also, yeast was dry, but new, and i just tossed it in there. still nothing resembling vigorous fermentation.

With that low of an original gravity, you probably weren't going to see a real vigorous fermentation anyways.

Yeah, let it ride. But I do recommend rehydrating your yeast first. It will give your yeast the best chance for success.
