May I ask what pitching protocol you guys have used succesfully with the S-04? I rehydrated for 15 minutes and pitched.

i just wait for the wort to reach ferment temps or get just a bit cooler and pitch the yeast directly in...no rehydration. that's with us05 not 04, though i'd think their characteristics would be similar.

Do you shake it up or stir it at all afterwards?

For ales up to around 1.050, I just open the envelope and drop it in after aerating the wort sufficiently. Truthfully, I don't use dry yeast often - but always have a few sachets in stock when the brewing bug bites and I've not had enough time to grow yeast up from a slant or a washed slurry.

I've rehydrated a few times in the past, but never noticed any differences in flavor or attenuation vs. a direct dry pitch for low to moderate gravity ales.

the only aeration is from my wort chiller when i'm cooling the wort down. that gets the temp to about 85*, i place the fermenter in the ice bath overnight and pitch in the morning usually at about 57-60* and i let it ferment at about 63*.
i just make sure and sprinkle the yeast all over trying to avoid any heavy spots that would clump up.
it takes a day to get going and then about 4 days fermentation and then it's done.
i leave the beer in primary for a week after that to dry hop and let the yeast clean up a bit and then i bottle. so two weeks total in the primary.

I think I will get my hand on some more S-04 and give it a try on a much lower gravity ale. The US-05 seemed to really go after the 1.070 and start fermenting strongly in less than 8 hours. No rehydration or anything.

You are probably right, at least there will be enough yeast to get the job done!!

Yeah wow, add me to the ranks of the confused. I've never used S-04 on a high gravity brew, but when I've used it it's taken off like a rocket and often reached FG in around 36 hours! S-04 has always been my go-to yeast for when I'm too damned impatient to wait for a liquid yeast to do its thing.
Maybe it's the rehydration. I've never done more than just sprinkle the yeast directly from the envelope.

I'll chime in with my recent S-04 experience.

I dropped two 11g packets onto my 1.081 OG RIS with wort temp at 70*, and when I came back home 18 hours later I had not just fermentation, but very active blow-off as you can see in my video below.

4 days after pitching my gravity was at 1.029. I'm going to leave it in primary for 3 weeks total then bottle.
