!!! My Hydrolock Is Not Bubblin Is My Beer Ruined What To Do Help Me ASAP !!!

But it was stated in the OP. He is measuring gravity. I posted his quote, but here it is again.

So the way you posted it originally didn't look like it came from the same quote. If you'd quoted the same verbiage in one quote box and bolded the statements it would have been more obvious to me.

Still why do you feel it's so important to point out another's transgression and fill up this thread with useless comments. After all it was just a quick question and the OP satisfied me afterward with their reply.

Perhaps I too could ignore your jab, but I have adult ADHD. So I tend to be in a hurry and skim what I read way to fast. And I'm inclined to defend myself!

Otherwise don't worry about it. I'm not bent out of shape at you. Just wondering why you feel compelled to point out mistakes of others. Or how it helps anything if there aren't arguments based on that mistake.

My humble, intentionally silly-titled thread is getting to be a bit hotter place than I expected.
Gentlemen, all of you are awesome with your valuable inputs, and the Old Slug Porter in question is happily bubbling in the room.
Today, I put another fermenter next to it: I brewed a Samuel Smith Nut Brown Ale clone, fermented with Lalbrew Windsor. Hope it starts well.
Peace and cheers!

Well, a follow-up.
The beer is ready, carbonated and long bottle-conditioned. A tasty Porter, light in Alcohol (4%) but pretty chewy (84% Pale Ale, 8% Dark Crystal, 8% Black Patent). It would make a very nice beer if not the soapy twang in it.
As I understand, the soap offlavour has something to do with decomposed lipids from dead yeast cells. I've had that twang once, when I left a Burton Ale in the primary on the lees for 4 months. Here, just 3 weeks of primary. And still.
I'll drink the batch up, it's not as bad as to dump it. As the last shot in a long session, probably, when the tastebuds are numbed.

My takeaway is that even 4 days on dead yeast pre-fermentation fill the beer with autolysis (or whatever else that soap comes from) flavours.

 

[balrog]

I've done plenty of 3 week primaries and never experienced soap.
Or twang for that matter, that wasn't obviously due to kveik for instance.

 

[Protos]

I always do 3-week primaries (except for Weizens and for ultra-low-gravity Bitters) and I never experience soap.
Except two instances of my total 271 (yeah, that many I've added to the 258 in the original post of Oct 13!) batches: a Burton 4 months on the lees and this Porter with two unsuccessful dead yeast inoculations.
Then, 3 weeks of normal fermentation with a fresh yeast (at the day 4), and still the soapy twang.

If you get excessive amount of trub into the primary, this could cause this. The fatty acids in the trub get saponified with excessive time.

If you don't have the excessive amount of trub, no problem.

... Or maybe a mix with the yeast autolysis?

 

[Protos]

Did not have any excess trub in this batch. A perfectly normal batch, just two inoculations of dead yeast in course of 4 days.
When I do have excess trub (and I do often), I don't get soap.
The soap comes exclusively from the dead yeast, I'm sure. All other variables are just like in my other good beers.

Then...... It might be the yeast!

 

[Protos]

I think so too.
If I knew that, I'd dump the batch pre-reinoculation.
Now, when it's ready... I never dump my beers. (Well, I did that maybe once or twice when I was gettin not just a substandard beer but a pure horror in the bottle, like for example my latest "Rosenwein" with 20% of schitty Wodka with beautiful Rose petals steeped in it).
So now I have a new addition to the long queue of "last shots" to my extensive drinking sessions, which happen not as often as I would have wanted them to, I must admit

I actually started to dump more stuff. My girlfriend made a fair point once "don't drink what you do not like, because there's just no point in it". She's right. Plus I really like brewing, a dumper means I can brew again quicker. If I got a beer that's substandard, down the drain it goes, empty bottles here we go.

 

[Protos]

I would do the same if here, in The Valley of Tears, brewing ingredients didn't cost me about twice as much as in Europe.
Mr Protos MUST drink what he brews That's good. Combined with prolific brewing, it teaches responcibility in recipe and technique choise

 

[VikeMan]

As I understand, the soap offlavour has something to do with decomposed lipids from dead yeast cells.

Another possibility (besides a large amount of trub, since that's already been discussed), is lipids from the malt. They are fairly small and don't (necessarily) have to ride along with trub. A good vorlauf can help prevent excessive lipids from malt. If you've ever noticed that dull, greyish fatty layer on top of a grain bed, that's (partly) lipids.

 

[Protos]

I don't know. I've brewed with the same batch of malt before and since that unfortunate brew and didn't notice anything unusual.
The only variable was the yeast.
The only thing I wonder, is how did the dead yeast have the time to leave a pronounced soapy flavour during a standard-length fermentation. 25 days in a 6L / 1.5G fermenter is definitely not enough for the real autolysis to manifest.

 

[VikeMan]

25 days in a 6L / 1.5G fermenter is definitely not enough for the real autolysis to manifest.

Depends on what you mean by real. Autolysis is happening all the time. With liquid yeast, it's happening in the package. With dry yeast, it's happening as soon as it's rehydrated. (Not to mention that the dry yeast packs probably contain some cells that were autolyzed before drying.) Yeast health, wort/beer conditions, and time will ultimately drive the rates.

I'm always baffled by comments (not yours) like "autolysis doesn't happen at the homebrew level." It does. The important question is at what point it becomes detectable and how bad.

Another thing you might wonder is whether the dead yeast in those sachets really contain enough lipid to be the sources of the soapy flavor even if completely autolysed. I doubt that it's within several orders of magnitude of what you have at the bottom of your FV after fermentation is complete.

 

[Protos]

Depends on what you mean by real.

My definition is "above my personal taste threshold". Which is apparently high, since I've experienced the soap only once, and the reasons were obvious to me: too long in a primary. Now, the reasons are more obscure which confuses me.

I doubt that it's within several orders of magnitude of what you have at the bottom of your FV after fermentation is complete.

Exactly. The volume of trub/yeast was not larger than in a perfectly normal batch.
