Sometimes The Day Doesn't Go As Planned....

[daryl]

UPDATE - the carboy and contents are up to 95F.

There is not alot of out-gassing, but there is more sediment in the bottom of the carboy...probably from the lacto kicking in.

What was interesting, there was significant trub from the wild/spontaneous fermentation that occurred, that I observed when I racked this Frankenstein into the carboy. So I am wondering how much fermentable sugars are available to the lactobacillus?

Will crank it up to 100 this evening.

How long should I keep this creature in the fermentation chamber? What do I monitor (SG, pH, ?)?

And, should I finish the kettle souring process, and add a beer yeast to finish - or go straight to bottling?

Borrowing the name from Steven Prochaska; if this turns out decent, I am going to call it Dankenstein!

If it doesn't, it will be good starter for the septic tank!

Checking your pH might not hurt. If it is above 5 add sone lactic, or a small bit of phosphoric. It always took mine a while to get started.

So this batch set at 100F for almost a month; and the Lactose really did not take off. It has been in the fridge now since then at about 45F.

Some have sampled it, and it seems to have the proper 'funk' taste, but it needs the lacto-sour.

Pat suggested I brew 5 gallons of sour and blend...not a bad idea; and I get 10 gallons of beer.....not my most favorite style, but if it's good, I am sure I can get some help liquidating it.

But Mark was talking about using 88% Lactic Acid....sounded like the acid acted as a catalyst to get the lacto to kick in.

After all of this time, if I raise the temp on this beer, is there any reasonable chance that adding the lactic acid will have the desired effect? I was thinking of adding a eighth of a teaspoon? Should be more?

If I do add it, and it succeeds, how long will it take?

You go to BIY and buy a little bottle of lactic acid. Add a bit at a time until you get the level of sour you want. Then you are done. Keg it.

If you hopped the original wort the lacto will never do anything.

I can do that. How much would you suggest I add for five gallons?

That is exactly what happened. And what makes this more surprising is that the wild yeasts took hold. When I make my plambic wheat base, I will use debittered hops.

Ok, so I've learned quite a bit from this.

Thanks everyone.

Yes, I've learned from reading this too. Good discussion. Thanks all!

Those will still stop the lacto. most lacto is VERY hop-sensitive (even 1 IBU equivalent will stop it). Boil with no hops, and when desired acidity has been reached, then add the dried hops to the fermenter.

Just curious Daryl, what was your calculated IBU's? I read a lot saying 10-20 was still ok with lacto, my sour is about 6 IBU and I'm freaking out now.

Sorry Travis, the IBUs were just over 20. How did your sour come out?

So...I am still dinking around with this carboy of dank. It has been at 56 degrees for months....three or four circles of growth are floating on top of the beer (nickel to quarter sized), is this to be expected?

I have the lactic acid to sour it...and will probably do that soon.

But in the meantime, the wild yeast or bacteria that took this batch over, I am thinking left behind fermentables for yeast. Should I pitch some ale yeast in there and see what happens prior to souring it?

It’s getting sour, I pulled a sample just before xmas and it’s getting a good sour aroma. The taste isn’t quite there yet.

What is the ph of the beer at this point? How much has the gravity dropped from the og? What do the circles of growth look like? Are they fuzzy or green/blue at all? If they are just white and not fuzzy at all should be nothing to worry about. I don’t know about pitching yeast at this point, kind of depends on what the gravity is I would
think.

Sorry to ask so many questions [emoji3]. I’m just more curious than anything. I recently did my first kettle sour and ran into a few things along the way so I’m curious how yours will end up in the end. I did end up pitching more yeast with some honey in mine after about 5 weeks since I thought there was still some fermentation to be finished but it didn’t really do anything and I think I might be throwing the whole batch away now since it smells terrible.

No problem, I'll try to remember to pull a sample this weekend. It the taste has gone south, I'll dump it.

The last time I tasted it, it had the funk, but no sour; I have the Lactic Acid to sour it up, but I think I might drop some active yeast in it to see if there are any more fermentables.

The lacto did not work in my case because I had hopped the wort.
