I have a Orval clone that has been in the bottle for 9 months at cellar temps. It has changed a little sampling here and there. I thought it was becoming oxidized . I had a friend who is a brewer at a local brewpub try it and he said it's the brett starting to come through. I think you should allow a good year for this beer to develop. But yes, drop it in and wait. I dont think you can rush brett.
