Bad lot of Safale US-05

[ayoungrad]

I just did a 1.082 ale with US-05. Started bubbling 6 hours after pitching. Expiration 6/2013. So, if there was an issue, it does not seem to be a persistent one.

 

[wilserbrewer]

FWIW I pitched US-05 a few days ago, 71322 124 1510 05 2013, I was satisfied and was actually a bit surprised at the kruesen at around 24-36 hours.

I pitched a lot of US-05 yesterday that had an expiration date of 5/2013.. it has yet to start fermenting. If it doesn't take off soon any advice? Should I pitch another packet of US-05 or a different yeast?

Give it a little time. Noticable activity can take up to 72 hours.

That being said, I did an Imperial Stout last week. OG was 1.085, pitched two packets of refrigerated US-05 which I think had the 5-13 expiration (I don't normally pay much attention), and it was surprisingly slow to start up. It did eventually build up a nice kreusen, and I haven't taken a reading, but I've never seen US-05 this slow, and I us it all the time. Looks like I'm going to have to monitor this batch closely. (For the record, it smells fine, exactly like I expect, so I'm not too worried.)

My 1.071 DIPA is at 1.023 today. Still fermenting strong, it should make it down to 1.010 to 1.012. But it's day 6 now. This is usually a 4-5 day ferment for me

 

[jma99]

Pitched two batches with US-05 marked with 5/2013 this Saturday and both took off within 7 hours. Looks good so far!

I pitched s-05 24 hours ago and The krausen is 1" thick. She's going like mad. It is: 71322 125 1825 05/2013.

 

[iaefebs]

So the problem doesn't seem to be widespread with that particular exp date. Not so clear on batch numbers. Nice to compare notes using exp. dates and batch codes.

 

[starrfish]

pitched an older this weekend... no probs quick start, checked my date on last pack still older stock... keep me informed ordered new.

 

[peterhdk]

I'm going to attribute mine to fluctuating temps: this fall weather & my thermostat has my heat going on and off. I don't have any temp control or heating pad on my fermentor. I think it probably just went dormant for a couple days.

I checked my imperial stout, and it was down to 1.018 and kreusen had fallen, so I think we're right on schedule.

 

[jtejedor]

I noticed the same thing last two packs of US-05 I used. The beers fermented down but were slow fermenters and were kind of stubborn to clear. Sorry didn't keep them around so don't know lot number.

 

[TheBrewinator]

Just checked the last packet I pitched Saturday night. It was dated 6/13, sprinkled it dry, and there was a nice thick kraussen Sunday Morning.

 

[CrystalShip]

I pitched two packets with an expiration date of 5/2013 and it did take a little longer to come alive... I think the culprit may have been the 1.101 og imperial stout though... it's chuggin now

Yeah, with all that food available the yeast was probably trying to figure out what to eat first.

 

[scottland]

Came home from a 5 day business trip and it finished at 1.010 down from 1.071 -- Exactly where I wanted and expected it to finish. So I can definitely confirm, attenuation is right where it should be. Just a slow ferment, and the yeast is slow to drop

I love us 05 and have noticed my last 3 batches Krausen is still high 7-10 days into fermentation.

I have an amber ale at full Krausen and it's on day 7, Krausen started on day 2.

I have the exact same scenario. Amber... US05... 7days.... Krausen, etc...

Talked to my brother today who whipped up a RIS 2 weeks ago, 2 packs of S-05 fermented down to 1.010 with a nice fluffy krausen.

I also brewed a Double IPA a month ago with 2 packs of S-05 that turned out great, I can't remember the last time I got a lag time over 6-7 hours with S-05.

 

[nilo]

Popped open a bottle today just to double check and although the beer looks beautiful, the phenolic taste is still very strong. It may be a lost batch. Will wait couple of weeks and try it again. I'm almost positive that this is a yeast issue. I have two packs left of S05, same lot and exp date and will trash it, just in case.

 

[ToddO]

Another case of 2 long ferments 7+ days before drop out. First finished a little high but I dont think it was the yeast. Went to dry hop the second last night at 8 days and was surprised at the size of krausen when I opened the bucket. 2 day lags on signs of fermentation on both which is somewhat long from what I am used to. I use this yeast almost exclusively so I did think something was off but didn't think much of it until this thread. I dont mind long ferments (preferable to a 2-3 day blowout) but the last couple have seemed a little long...Will still use this yeast BTW..

 

[HopSong]

Got a little concerned when I saw this thread. It's not only my first experience with Safale-05.. but my first with an extract using steeped grains. I was patting my self on the back about what seemed a good working process. I also have Batch Number 71322 125 1824 with an exp date of 05 2013.

Here's hoping.. I pitched the yeast as a dry sprinkle.. I got "overwhelmed" with my first batch using a full boil and the grains. I think I got everything right except hydrating the yeast.

If the yeast is good.. I should have something going tomorrow or the next day.

I had an interesting thing happen here. The OG was supposed to be 51-54.. mine was 56.. no biggie here.. but, I also had a larger volume than I expected.. It was supposed to be 5 gal.. but ended up being 5.3 gals..

Hope this is a good thing.

I'm excited.. unless the yeast doesn't kick in....

 

[terrapinj]

here's my cream ale - 2 weeks old down to 1.008 from 1.052

not crystal clear but def not very hazy - going into fridge to cold crash now

(hydro reads .004 high)

 

[nilo]

Brewed another batch using S05 yesterday. 24h passed and no signs of life, like the previous troubled batch. Will wait and see what happens. I know some folks report up to 72h before start so I'll wait. I don't care much about the timing as long as the beer tastes good.
I had two packages with 5/13 date in stock but visited another LHBS looking for a different lot. Out of luck, bough a package with lot# 71322 124 1855 exp 5/13. Noticed the store keeps the yeast in a fridge, contrary to the store where I got the S05 previously, that let it sit on a shelf so decided to give it a try.
Rehydrated and pitched at 63F. Keeping at 63F.
Update on the previous batch, still showing a nasty phenolic flavor. Pretty much undrinkable.

 

[Ozzfest05]

I find with us 05 I see Krausen after 48 hrs never before. I just racked my batch to secondary it tool 16 days for Krausen to fall. Popped a cream ale open been 1 week in bottle (us-05) and it's almost fully carbed it's clear and tastes really good.

I love us-05

Do you rehydrate your S05. If so, can you describe your rehydration process/temps?

 

[Ozzfest05]

I brew mostly ipa and pale ales rehydrating has never help my fermentation to start early but I only use us-05. Actually today is my first time using us-33 I debate 05 but for the higher abv they recommended 33.

I just aerate so my wort has 5 inches of foam on top the sprinkle the dry yeast onto the foam slowly. The foam will start to quickly sink into the wort.

It's worked well for me.

Cheers

I brewd a cream ale over the summer with US05 that was highly phenolic. Brewed the exact same batch with wlp001 and it was excellent.

What temperature and what kind of phenolic taste did you get?

 

[erikhild59]

Fermented around 70F. Phenolic like a wit or grand cru I would say, drinkable but disappointing.
