faithinchaos said:oxygen ingress occurs through the bung and airlock usually and the container (carboy, bucket, etc) is pretty unimportant here. "wort reacting with oxygen" not sure what you mean here, but
ideally you should pitch a large culture of yeast and lacto with little oxygenation therefore promoting growth of lacto but still getting a good fermentation from your brewers yeast. or pitch a large starter of lacto 12-24 hours prior to pitching your brewers yeast and before the pH drops too low so you still get a good fermentation. if it gets too low before the yeast can complete a proper fermentation you might get poor attenuation which is why i suspect brett is usually found in these berliner blends.
you say you are a big fan of brewing with bugs but you are the same guy that doesn't think a 100% brett L beer would be good...
I've had 2 styles brewed with Brett L only - way too aggressive for my tastes, and my personal feeling now is simply that I don't expect to ever find a great beer fermented only with Brett L.
I can be a big fan of pizza (although what I said is that it's a huge interest - not quite the same), but it doesn't mean I have to like it absolutely smothered in anchovies.
Your arguments are continuing to devolve in a big way, and I can see things will probably just start going in circles, so I'll just leave it at that. There's a whole slew of brewers here who have aerated/oxygenated their Berliner Weisse and have had nothing but great results, so I'll let the evidence speak for itself, and people can make up their own minds. I'm not even sure why I bothered arguing, because I know a BW can turn out fine either way, oxygenated or not.
