What could have happened?

[Ameritoon]

Alright brewers...
Weird one here...
Yesterday I brewed 2 Irish Red Ales... One a kit for a friend (brewed at 3:30p) and a self-designed one (brewed at 6:30p). The kit used Safale-05, mine used Safale-04... not that this should have mattered. As you can see in the kit ale, a trub seemed to have developed - but no real activity, no active fermentation. My recipe is going nuts... frothing away happily. Both yeast packets were hydrated prior to pitching. Both batches were brought down well below 80F prior to pitching...

Could keeping the kit in a warm garage had an affect on the dry yeast? Ingredients for my recipe were purchased Friday evening. TIA!

How long has it been? Different yeasts behave differently. The other one probably just hasn't started yet.

Why would you say that? If all yeast behaved the same...we would only have one type of yeast.


S-04 ferments quick and hot and can easily get out of control without good temperature control.

Here is S-04 in one of my stouts (LHBS was out of WLP004) with a ferm chamber set to 62*F / probe dangling and measuring ambient air temp. Measured 79.5*F inside the carboy, and that was a bit after peak ferment, as evidenced by the amount of liquid already in the chamber.

"Well below 80" makes me a little nervous, since I would definitely want to keep both those yeasts in the 60s from pitch through active fermentation. It also sounds like it's been less than 24 hours -- don't necessarily expect a big krausen in that little time. I wouldn't worry until it's been 72 hours, really.

Thanks for the feedback boys... I guess I'm used to the wild fermentation of S-04, it seems to be what I used most... To watch the S-05 (which I have used in the past) react so slowly in a side by side comparison just seemed odd... I honestly was expecting some form of reaction by now - which is why I didn't think the difference S-04 v S-05 mattered...

And yes these were both brewed yesterday Jan 31st.

Keeping the kit in a warm garage could be bad on the yeast, depending on how long and how warm. I don't know how to correlate the time and temperature to yeast viability, but it's food for thought.

+3 on SO-4 being a beast. The one and only time I had to clean beer off my ceiling was from SO-4 blowing the airlock off my carboy. I don't use SO-4 without a blowoff tube. SO-5 has taken anywhere from 12-36 hours for it to get going for me but always with good results.

Alright boys, just to close the loop - and thanks again for the feedback... Here's a pic from this morning 11:10EST.

Starting working last night - krausen forming - but like others have said - nothing as crazy as S-04!

KatoBaggins - same here! I used it on a very heavy beer 1.084 OG... I was awoken at 1:00am to the sound of the airlock blowing out the carboy and what appeared to be Mount Vesuvius overflowing onto the floor!
