There is a huge host of Brett. Brett lambicus, brux, and cloussini are the e typically seen in the brewing world. Any Brett will grow. It is capable of eating all types of sugars. It is also very very difficult to get rid of. I do an immense amount of brewing. Usually 300 to 400 gallons a year. From the fermenter on, I have separate equipment for everything. Hoses, fittings, racking arm, etc. The wine world hates it because even in as small as 4 cells, it can grow and propagate. Brett is excellent at scavenging oxygen, and a few breweries have tried bottling with the lowest limits of Brett in their beers to help prolong shelf life (the idea was the Brett would eat the residual oxygen in the bottle). But even at 4 cells in the sealed bottle, the Brett was noticeable before the staleing effects of the oxygen was noticed. Anyway, sorry to be long-winded. I love brewing and especially brewing wild ales and have read more books, articles, thesis papers, and studies than I should admit! [emoji2]
