Scotch blending house Compass Box has launched the third expression in its Extinct Blends Quartet: Metropolis.

Metropolis is said to have been inspired from a recently lost blended Scotch whisky with a “long history”, and by the mixing of cultures that happens in cities. It includes some sherry cask-matured whisky alongside grain whisky and a small proportion of highly aged malt whisky.

Compass Box introduced the Extinct Blends Series to pay homage to blended whiskies of the past, which – unlike 'lost' distilleries that can be resurrected with like-for-like equipment – are incredibly difficult to recreate at scale. The series will comprise four blended Scotch whiskies created from the company's stocks. Metropolis follows Ultramarine and Delos in the series.
