Default How do you fix a Lactobacillus infection?

I have a Robust Porter that has been aging in a wine barrel for a few months. We took a taste of it and it seems to have a lacto infection. It is cloudy, has that lacto flavor, and is a little sour.

Is there a way to fix this?

Can I throw another bug in and make it a sour?

Or should this be an unfortunate dumper?

I don't know about making it a sour, but if its got lacto, its a done deal.

If it has lacto you have the start of a great sour beer. You can add the White Labs "sour mix" and come up with something great.

A robust porter should be too hoppy for most lactobacillus, at least the ones that make pleasing beers. It's possible it's pediococcus, which still makes lactic acid, but also a lot of diacetyl. It's more likely that you have acetobacter. How long was the barrel empty, how did you prepare it, and is it completely full?

Did you keep the outside of the barrel wet?
