Just want to share my observation
i made 10gal of saison and split it in to two fermenters, one got 3711 the other 1.5L starter from orval bottle (stepped up and active)
Fermentation started at 64 and i increased it up to 78 i think. Brett finished 2 days earlier than 3711, after stable gravity for a week (3711 at 1.001 and brett at 1.009 i think) i started cold crashing but with my system the lowest i can go is 45-52F and the strange thing happend at this temp. Normally when moving from 75-58 to 50F little air gets suck up in to the carboy and you can see liquid in the airlock moving in oposite direction, well not for orval (brett?) beer, it started releasing more co2 and airlock activity obviously resumed. After two days of cold crashing and airlock still bubbling i couldn't bottle it last night so i did only 3711, i will check gravity on bret in few days.
I tried tasting samples from og readings and two beers were very different, both good, but i was surprised how "normal" brett beer was, surprisingly 3711 had more mouthful
