How low can Brett go?

I’m thinking about getting a funky and/or sour beer ready for the spring, but I can’t really justify keeping my fermentation chamber warm for a couple months while the Brett does its thing. Anyone know if it will ferment reliably at ~50°F? It’s B. bruxellensis, if that makes a difference.

My example had more than just brett b, but…

Did a baltic porter(kind of I guess) with all brett (multiple strains, but there was brux in it). Primary fermentation was around 66 for 3 weeks (gravity got down to 1.013).  Then it went in the fridge at 52F for about 2 months.  Gravity crept down to 1.009 and stopped.

It’s a powerful critter in my experience and it should get the job done.

I’m in the planning stages of a sour lager now…  I’ll be interested in your results with just brett b.
