Thanks to /u/buddy_dosser for the sample via /r/ScotchSwap on reddit.
Kilchoman have joined the growing number of distilleries experimenting with smaller casks. The increased wood contact adds more woody character which would usually take a much longer maturation period to achieve. This shouldn’t be confused with faster maturation though as the spirit itself still ages at the same pace. This particular one is from a limited cask strength release for the full, unadulterated experience.
