Quick Sour Stuck Fermentation

[GundyGang1]

Hey Guys,

I have a saison I am brewing for a friend that started with a quick lacto sour, pitched lacto around 120 degrees after boil and let it sit with Wyeast and WL facto for 3 days. I then boiled for another 60 minutes, added hops and pitched Wyeast 3711. Saw a little movement in the airlock and let it sit for a week or so. Checked the gravity and it had moved from 1.065 to 1.05ish. Gave it another few days to a week and had not moved. I noticed when pitching the 3711 that the pack did not expand and wondered if it was just some bad yeast. I pitched some Berliner Weisse blend and some brux to see what would happen. It's down to about 1.045, but it's been there for a couple weeks...

Any help with this?

Can pitching lacto for too long create fermentation problems?

Any way to salvage?

Ive added a couple more viles of wlp648 just to see if Brux would take it down after time, would that work?

Give it time, toss it?

Odd,

That 3711 should have ripped through that wort, but the smack pack definitely should have swollen.

Similar story:

I brewed my raspberry two months and for the first time I used Wyeast lambic blend Instead of just raw grains in my sour mash. The beer ended up way more sour than any other batches and this was the first time using 3068 that it stalled at 1.020 on me.

The only difference in the batch was the lambic blend and I'm sure that I had a very low PH in the fermenter before adding the yeast. Yeast grow optimally between 4-6 but aren't supposed to have any trouble down to even 2 but I've read of many people having just that issue.

Beyond pitch rates, temperatures, dead yeast and overall fermentables I have nothing for ya!

I know! I've used it before and it's been a beast, so I thought it was weird that the pack didn't swell...

Anyone?

Maybe the pH got too low for the yeast and stressed it out, combined with not having a healthy number of cells?

 

[GundyGang1]

I wondered that. Is there a way, if that is the case, to pull ph up at this point?

Ok, Ph is at 3.77, so not crazy low. Gravity has moved a little down to 1.039. Am I just needing to wait for this thing? It's moving slow, but moving.
