On the temp, Beaufort AOC calls for an aging "at a temperature below 10C." It makes sense, to me - long, slow aging. On the hot build, I think I saw Sailor discuss this somewhere, to finesse the propionic development. Relative to its kin (comte, emmental grand cru), the propionic is quite muted - .05-.2% propionic acid, compared to 1-4% for comte, 3-4.5% for emmental grand cru.
I only use aging containers for my reblochons - the Beauforts are in the open cave, and in the other cave, I have all tomme grise.
