Mixed culture fermentation

I’m thinking of using my oak barrel for cider since I wasn’t to happy with the beer results. Had better control with cubes. I’m thinking to put some apple juice in it and pitch in a mixed culture of lactic/Bret/Sach that I’ve harvested. Anyone have anything to add? I’ll hopefully be able to use the barrel for sour some beer after its inoculated.

Nothing to add other than that sounds delicious!

I like oak chips the best. Seems like a lot more surface area for a half of the cost.
