Black Stallion is a Barrel Aged Russian Imperial Stout from Brouwerij Bak 'n Ros in Den Ham, Netherlands, with a robust 10.0% ABV. This ambitious beer marries the full, dark character of an Imperial Stout with the added complexity that barrel maturation brings.

The brewery worked from a single 2000-litre base batch to create multiple variants, reflecting their experimental approach. The barrel aging introduces layers of oak and wood character alongside the stout's natural dark malt and chocolate notes, creating a layered, warming experience.
