I guess you could put them on a stir plate and let them dance, not sure why I thought they where no good but I didn't add them to my sour.
It does say 100% fermented with brett but I couldn't see where it talked about being bottled with more. The bottles are nice and thick so I'm saving them for my sour. I intended to just toss dregs in there as I did with the Brett Saison. However, I think I'll see if I can wake them up and keep them in vials I have because I was going to add more brett when I racked to secondary and added more blackberries and oak.
It needs more time though. The sour is young. It was unintentional after all.
Coffee and water.
