Looks like infection before even pitching yeast

[urg8rb8]

Friend brewed, put wort in plastic fermentor, and didn't get around to pitching the yeast until five days later. Opens the lid and sees lots of bubbles on the surface. Infection? Pitch yeast anyway and see what happens?

 

[DatsyukianDeke]

There's no way to know for sure without a picture. Bubbles could just be gas escaping, could be a infected, who knows?

If the wort makes it into the a clean and properly sanitized fermenter it could keep for a bit before the yeast was pitched. Five days might be pushing it. I usually chill down to about 70 then let my ferm chamber do the rest. I'll sometimes wait a couple days before I get around to pitching and haven't had a y issues so far.

I updated above with a picture.

It's fermenting (there's yeast in it). You made beer!

Maybe it's yeast from the last batch in that bucket, or maybe it's wild yeast it picked up on brew day.
I wouldn't pitch anything new. See how it turns out on its own.

Good luck!

could it be bacteria?

 

[RPh_Guy]

Only yeast produce foam like that, so there's definitely yeast making alcohol.

There may be both bacteria and yeast.

This is very interesting. But he JUST pitched the yeast. Hopefully, the WLP004 will overpower the yeast already there.

 

[RPh_Guy]

Unlikely, but that's fine.
Hope it turns out ok.

I gave him the idea of auxiliary yeast eating the sugar and he told me that the fermentor had yeast cake on the bottom that he probably didn't completely scrub out. so it makes 100% sense that is it yeast from his previous batch. The previous batch was used US05... it probably already fermented out most of his beer lol

Not completely cleaning his fermenter before adding new wort and not pitching for 5 days is begging for trouble IMO!

It was sanitized though.

 

[kingmatt]

It was sanitized though.

If it's not clean, it can't be sanitized (as evidenced by the leftover yeast fermenting the wort he added).

 

[RPh_Guy]

That nasty dark stuff in top of the kräusen is the old yeast cake? Gross.

I know what you mean. I don't think the bucket was fully scrubbed.

Hahah sarcasm?

 

[RPh_Guy]

No, it's a little disgusting using dirty equipment, even though it's probably not harmful.

Would you eat off of dishes that had a layer of old food caked on it? Or use beer glasses with a dried layer of beer on the bottom to serve beer to guests?

In all likelihood that beer is contaminated with wild microbes even though there's no evidence of it yet.

Isn't there always stuff on top of the krausen anyway? The fermentor wasn't crusty. It was washed, wiped down, and sanitized. I watched my friend clean it. Maybe there was some yeast stuck in some of the edges at the bottom of the bucket.

 

[RPh_Guy]

^ this painted a different picture.

I won't be drinking it either way, so it's all good.

Cheers

P.S. Get yourself a good cleaner like PBW or similar and give your equipment a warm soak immediately after every use. Rinse before and after the soak.

Might be the best beer ever, we shall see haha

Yeah, I hope it's good.
Pitch sooner next time

My friend and I brewed two batches together. He couldn't pitch his yeast earlier because he was waiting for his new temp controller to ship from Amazon.

 

[rburrelli]

It was sanitized though.

Sanitizing does not kill germs.

You mean yeast?

No. Sanitizing does not kill germs. Sanitizing is not the same as cleaning. If you don’t clean properly then sanitizing will not help.

 

[bigdawg86]

So it begs to be asked... why did it take so long to pitch yeast? That's the easiest and fastest part of any brew day?

Oh and that Krausen looks fine to me.

Because my buddy that was brewing with me didn't get his temp controller in the mail yet until yesterday.

 

[bigdawg86]

Well we can file this under don't start a brewday unless your 100% prepared. Live and learn. Who knows the beer may turn out good, I would certainly let it ride and bottle or keg it.

He had US05 in that bucket previously and the wort has been sitting in high 70s room temp. Hopefully the off flavors aren't too noticeable.

How is it possible that tiny specs of yeast can start fermenting 5.5 gallons? All these yeast pitching calculators say you need ridiculously more yeast.

 

[RPh_Guy]

Appropriate pitching rate leads to faster fermentation, less risk of contamination, and much lower risk of off-flavors.

Yeast is alive thing, it reproduces. Thing is, less cells you have the more time yeast spends reproducing instead of fermenting, which may lead to off flavors or, in worst case scenario, contamination if another microbe manages to take a hold before yeast gets strong enough.

 

[urg8rb8]

Just to follow up on this... 5 gallons down the sink!

 

[Philip1993]

Why? Describe the flavor?

 

[yourlastchance89]

You have that a little mixed up. Sanitizing does kill germs, but it's not as effective if it can't pierce microbial buildup or biofilm. Cleaning is supposed to break up that build up or biofilm. Sanitizing is not effective without cleaning and cleaning does not kill germs.

No. Sanitizing does not kill germs. Sanitizing is not the same as cleaning. If you don’t clean properly then sanitizing will not help.

It smelled like sh$t and it tasted worse! lol

My friends described it as what a nasty, sweaty sock would smell like after wiping your ass with it lol

 

[RPh_Guy]

cleaning does not kill germs.

The hydrogen peroxide generated by PBW, Oxiclean, and other percarbonate-based does kill microbes rather effectively.

sorry to hear it turned out like a bad porno.....i once had half a batch start fermenting in my mashtun that i was keeping it in, till i got an empty fermenter...never tried it...

I had one like that. Nasty yeast. I kegged it and waited. 1 month later, same. 2 months later, same. Undrinkable. I forgot about it in the back of the fridge.

4-5 months later I needed a keg and was going to dump it. Seconds before I dumped, I decided to give it one last taste. Hooked up a picnic tap in the yard.

Best beer I have ever made..

Define “germs”. If you use Iodophor it kills yeast, mold, fungus, gram positive bacteria, gram negative bacteria, spore forming bacteria, viruses and blood borne pathogens.

Yeah. I realized after I responded to the post that I was incorrect in how I stated it. Just never bothered to do a correction. Brain fart. Sorry about that.
