It's accurate in the sense that he did it and it worked for him, but you can go a different way.Wondering if anybody has info on Chichum timeline post, post #165. Is that accurate or have others racked to secondary(or left in primary), added oak cubes, and bottled at different times?
I typically use a shorter schedule up front (three weeks in primary, three-ish weeks in secondary with oak) and then let it age out in the keg for a few months from there.
Last time I made a tripel I aged it in a used brandy barrel. Came out remarkably similar to this.
