ive never used it, but every time ive used brett its been a blend. I read somewhere that blends are usually best since a single strain can be a bit 1-dimensional. Hops can fix that though
Ive fermented my brett IPAs at room temp with no temperature regulation. They can easily get into the 80s without any off flavors. I would definifelty let it free rise to get the most fruity flavors from it.
Ive done 3 all-brett IPAs so far that each fermented for 3 weeks. They wre done at 2, but I was still a bit paranoid it would keep attenuatiing like it does in a mixed fermentation
ive got 4 brett-spiked beers and they were bottled a bit after 2 months. 3 of them were mixed with saison yeast and 1 ive got going now is a brett-wit. If you do a mixed fermentation, id recommend pitching both brett and sacch at the start for faster flavor development
