I started one of these 5 months ago. According to my notes it came with toasted oak sawdust and I added it on Day 1 to my primary.
The RM is aging in a carboy now and I've only tasted it a few times. It doesn't have as much oak flavor as I like, but I think if someone doesn't like much oak it's fine. A couple of weeks ago I got a new 40L Vidai barrel in which I have a CC Amerone. My plan is to start another Red Mountain kit right after Christmas and when it's done fermenting, remove the amerone and barrel both Red Mountains together.
