Pediococcus contamination--Will brett get rid of the ropiness?
Without a photo, it sounds like you have the makings of a pellicle, although the statement "a thick ropiness below the surface" is a bit confusing. Pellicles form on top of the beer, and ...

Will Brett C contaminate my equipment?
The standard wisdom I've seen is, as mentioned, that glass and metal "should" be fine but plastic is much more prone to scratching, making it a concern.
Brett has a reputation of being very resilient ...

Sour Ale With Pedio but Without Brett
You're right on the common combination of pedio and brett due to diacetyl production. But pedio doesn't start working for 2-4 months, and has a time-frame of 4-9+ months. So you have plenty of time ...

Butyric acid producers like Clostridium favor temps around 104°F (37°C), which is also a similar temp ...

Droping beer with Brett in Carboy
Brett beers can be very interesting, and aren't necessarily sour unless the source also was sour. Brett usually gives more of a leather or "barnyard" character which can evolve with longer aging. ...

Pediococcus contamination--Will brett get rid of the ropiness?
An unorthodox (by today's standards) way to deal with it is the really old school way of using mustard seed.
When beer turns ropy without being sour, it is
easily restored by mixing in the ...

Brett aged beer - bottling?
Did you use real Brett Or Faux Brett (Saccharomyces "Bruxellensis" Trois)?
In either case it's probably dead or very weak, usually the Brett is added at the time of bottling.
Repitch your bottles

Sour Ale With Pedio but Without Brett
You can certainly pitch the Brett later. As mentioned the Brett will help with diacetyl, but it also helps with the ropey dextrinous 'gunk' that Pedi starts to throw in there. Without Brett that ...

Brewing a 1860-1890 IPA
Oak barrels also let a bit of oxygen in. Apparently you can recreate this with on of those soft orange carboy caps - they are more porous to oxygen than others.

Should I keep my batch?
In a sour ale the acid is suppose to balance the malt opposed to hops bittering to balance.
Sounds like you have an acid base for a blending batch. If you have a PH meter check it. Then blend with a ...

Should I keep my batch?
In reality if the brew is that malodorous and sour to taste then it is probably worth discarding. 1.75 gals is nothing in the greater scheme of things. The alternative is attempting to drink it! :0(

Yesterday the pH was 3.7. I drank a little and realized I made vinegar! The cheesy smell is gone, and the vinegar taste is overwhelming. There must have been too much exposure to oxygen. Oh well. Now ...

How can I deal with the diacetyl produced by pedio in a flanders red
It's best to catch diacetyl early and do a diacetyl (increase temp 68-72F) rest before racking off the yeast. Usually the diacetyl from bacteria is cleaned up by true brett, not so much by faux brett.

Why has Brettanomyces in secondary formed pellicle but no attenuation after 6 weeks?
Wait longer, they'll wake up some day.
For comparison, my most recent brett beer got brett b in the primary, fermented out to 1.010 (typical for the other yeast) and then sat for two month doing ...
