Thanks. I just ordered some lactic acid. I have experimented with acid malt recently brewing a Berliner/sour using this new 'Philly Sour' yeast. It definitely adjusted PH.... fun journey.

^ Thanks. Should I still be concerned if my mash PH is normally around 5.3 - 5.7? I know 5.7 is a tad high for IPA. Maybe adding a little acid would eliminate that. I use a digital PH meter from kegland. I will def look into it more. Thanks

Can you or someone please direct me to a good article or video on this subject? It's something i seem to be lacking knowledge. i've seen acid malt in other people's recipes on beersmith and always wondered why. I remember trying to goggle search about it but didn't really find anything. Thanks

For what it's worth, i just sampled the Munich Helles (11 gal batch) out of the conical and it tastes good. No off flavors at all. This brew was done after batch # 2 that got dumped and a week before batch #3 that got dumped. #2 was done in the same conical

Was there an off flavor? Or just didn't do their jobs properly?

Wow. Seriously? I had a vision that more and more homebrewers were going to start coming out with similar complaints/issues. This really will be interesting. I swear my gut just tells me something is wrong with this yeast. Obviously I could be wrong. What would happen if their packaging got...

One thing I just thought of. I have a Munich Helles that is in the conical going through a diacetyl rest. It will be interesting to taste it and see if it has the off flavor.

Interesting. Thanks. The vomit might be a good description. "watered down vomit". It is interesting to think about infection. 2 different fermenters at the same time. Maybe the hose I'm using to transfer is bad? Although fairly new. And I soak it in PBW and wash. Or something with the brewzilla...

Actually no. I rinse with hot sink water. But this has always been the case for years and have never tasted anything at all. It is usually 5 days evaporated by the time i brew. But i guess the residue from city water is still there. I have never tasted anything like this current problem before...

Damn. That's a pretty expensive experiment. But I might have to give it a go. Just wondering... what if they both fail lol. Then what would you think the problem is? Also, I have made this beer successfully prior to these 3 brews. I also brewed a very similar IPA using us05. All in the same...

I'll give you the bold. I went back and re-estimated my brewing history and was much less. I can't exactly remember how many since 2013. Definitely over a 100. I guestamate 120. Maybe i should have used the "guestamate" Also, i made a typo in the "I have fermented 12 successful batches in the...

Yea I like cleaning it up. I normally clean it with half gallon PBW mix and run the pump and let it soak too and scrub. Then I dump and do the same with Hot water. Then Starsan... And then one final rinse of hot water. I heard StarSan can help rinse the PBW residue - that could be a myth tho...

I soaked everything. But I also did batch #2 in a separate stainless conical with same resulting flavor.

Makes me think something is going on with the sparging. Even though It's the same process I've always used with this brewzilla system. Probably close to 20 brewdays in the Brewzilla with good results

I can say this I def need to do this more often. I do here and there. Normally taste the grains after mashing/sparging. The last brew I made sure to taste the samples and tasted great. I need to do this more often though.

No. I haven't fermented in the Firmzilla with a successful batch since this issue. The last 2 done in the Fermzilla were the dumped brews. 1 batch was brewed in a separate 13 gal conical and the same flavor resulted. Prior to these bad batches I had around 12 successful batches done in the...

Thanks. My wort chiller is Stainless. The Brewzilla is stainless. Firmzilla is plastic

Thanks. The temperature prob in the brewzilla I never trust but I have a system down using a separate Thermapen that I trust. I have 2 of them and just checked the temps with the same water and they both are reading the same. I will boil some water and see what happens tho. I fly sparge around...

RO water with salts adjusted via beersmith (Hoppy pale ale). Other brews taste great using the same water

Lol no. Sorry i meant 2000ml. I will edit
